We are proud to announce that our long-term partnership with Transsion has materialized.

Their first smartphone with Tempow Audio Profile has just been launched last week in India: the Tecno Spark 6 Air. As one of the most advanced smartphones available to Indian consumers, providing a revolutionary music listening experience had become essential.

Transsion is Africa and India’s top smartphone manufacturer with 3 brands: Itel, Tecno, and Infinix; and one of the 10 biggest smartphone manufacturers worldwide.

Transsion Holding is an incredibly dynamic company, with TV, Speakers, and True Wireless plans, and we are super excited at Tempow to be part of this journey.

Stay tuned.

About Tempow Audio Profile

Back in 2016, we rewrote the Bluetooth protocol to be the first one to unlock multi-stream capabilities. Today, integrated on millions of handsets Tempow Audio Profile enables their users to effortlessly play music to up to 4 wireless speakers or headsets at the same time. Transsion was one of its early endorsers and adopters.

Transsion (largest Africa’s smartphone manufacturer!) is our new global partner was originally published in Tempow on Medium, where people are continuing the conversation by highlighting and responding to this story.

We’ve faced some challenges like how to keep connection with the team? How to maintain some natural spontaneity in our interactions?

So we decided to create a Discord server, in parallel to our Slack.

We created “rooms” where people are always connected during the day, matching the physical rooms that we have at our offices.

The main idea is to recreate an “always-on situation”. Something that represents a persistent audio line.

Our entire team keeps Discord always open on our desktops, on mute, in the background, but with the speakers on. When someone wants to say something, they just unmute themselves and start talking like you would do at the office. We’ve even created some specific meeting rooms (“Salle de Réunion” in French!) for different teams and topics so that the conversation stays relevant to team members. And if someone wants time to focus, you can easily silence the incoming audio and your coworkers will see that with a matching icon.

At this point, you may be wondering “ok, this is great — but how is it linked to what you’re building at Tempow?”

Well…as you may know, at Tempow we are building an OS for True Wireless Earbuds (Airpods-like devices) our uniqueness being that we redeveloped the Bluetooth protocol from scratch.

Obviously, the entire team is constantly using True Wireless Earbuds to test different products and features… and it made us realize that our Discord setup had a major issue.

Having Discord always-on forces the wireless earbuds to maintain a constant voice connection with the laptop. In Bluetooth terms, this voice connection is called HFP.

HFP is designed for Voice-only as opposed to A2DP, designed for Audio. Unfortunately, those two Bluetooth profiles do not work concurrently. It is possible to transfer Voice through HFP but the audio quality is miserable (16 Khz sample rate!).

We’re facing a dilemma: if we want to use Discord with our wireless earbuds,it seems impossible to listen to music at the same time.

How can we fix this problem? Some of our engineers started building a prototype.

A key insight we uncovered: when working from home, a user typically has a phone and a laptop. What if we could use the smartphone to stream audio and the laptop to stream voice at the same time?

After playing with the protocol, we managed to make something work!

What the video below:

This is the first proof of concept and while far from being ready to be deployed, it’s a good starting point and we hope that soon you’ll see earbuds with that functionality enabled in the market.

If it happens, it means that those earbuds will probably be powered by Tempow.

To be honest, we don’t know if that kind of feature will be really useful in the future for the context we developed it. Personally, I strongly believe in spontaneous voice platforms, but I’m still waiting to see if something will emerge.

That being said, it was a nice side project for us, and I can envision several applications for the underlying technology:

• Voice Assistant — we could have the assistant talking to you without cutting your music!
• Video Games — we could finally activate voice chats and still have a good audio quality!
• Infotainment system in the car — the driver in the car could have its phone call with its private speakers, meanwhile the passengers are listening to music.

Pretty excited to explore more of those!

Meanwhile, give us your suggestions for how we should name this functionality. We definitely need to find something better than “Dual Source A2DP+HFP” !

Cheers,

Vincent

How working from home is influencing our roadmap was originally published in Tempow on Medium, where people are continuing the conversation by highlighting and responding to this story.

The first time I met with an angel investor was in mid-2016.

When you create a startup, you quickly learn a few acronyms and use a bunch of metrics that are part of the basic glossary. TAM (Total Addressable Market) is one of those terms.

The definition is quite simple: when you pitch a company, the TAM is the estimated total revenue available for the product you are selling. Long story short, this angel investor challenged us on the TAM of what we were pitching him. In other words, our market size.

Paradoxically, market sizing can be quite subjective. There are two common approaches you can use for estimating your TAM: the Top-Down approach and the Bottom-up approach.

The difference between these two market-sizing approaches perfectly illustrates what we should all be aware of with the new Bluetooth Audio norm: LE Audio

What is LE Audio?

In case you missed it, the Bluetooth consortium just announced a new Bluetooth norm at this year’s CES: LE Audio.

This new generation of the protocol will significantly improve the performance of Bluetooth Audio and enable a new generation of Wireless Earbuds capable of substantial optimization from both a technical and user experience perspective.

But what is the real opportunity of Audio over LE at the moment?

In other words, what is the TAM for LE Audio?

Let’s start with a top-down approach

Let’s calculate the TAM of LE Audio using the top-down approach. How might we do that? Well we simply look at all the Bluetooth Audio devices shipped annually (Headphones, Earbuds, Hearing aids, Speakers, Soundbars).

And boom! Looking at that graph, the TAM for LE Audio is tremendous with roughly 1 billion products shipping annually and increasing. The opportunity is huge, there is no doubt about that. That’s the TAM shown by any company working on Bluetooth Audio at the moment.

Or is it? Let’s see if a bottom-up approach brings us to the same conclusion.

The bottom-up approach to calculating TAM

In order to do so, we need to dig a bit deeper into how the Bluetooth protocol really works.

The reality is that there are two distinct versions of the protocol co-existing today:

• The new norm we just discussed, LE Audio
• The old version that we all know, Bluetooth Classic.

/!\ Important /!\

If there are two things you absolutely need to remember about these versions of the Bluetooth protocol, it’s the fact that both are:

1. End-to-End solutions
2. Hardware-dependent solutions

What does that mean exactly?

1. “End-to-End” means that both the source device (smartphone, product, tablet, TV) and the sink device (earbud, speaker, etc.) need to support the protocol. If you want to use the LE Audio protocol, you need a speaker that supports LE Audio as well as a smartphone that supports LE Audio.
2. “Hardware-Dependent” means that the Bluetooth Hardware component (ie. the Bluetooth chipset) is different depending on the version of the protocol. It also means that in order to support LE Audio, the different devices cannot be simply updated with a software/firmware upgrade, but must be equipped with a different Bluetooth chipset.

Now that we know the importance of a Bluetooth protocol being End-to-End and Hardware Dependent, let’s look again at our TAM for LE Audio to see if it’s changed.

What is the TAM of the LE Audio market today, in February 2020?

The answer is $0.

At the moment, no user, nor brand, can benefit from the recently announced LE Audio protocol.

Why? Because we first need to see a hardware renewal cycle of the source devices (the smartphones, the tablets, the laptops) before it’s possible to use audio sink devices over LE Audio.

To put it simply: we need to have a new generation of smartphones equipped with the latest Bluetooth chipset supporting LE Audio before we’re able to use LE Audio with our Earbuds.

When will that happen? The Bluetooth Consortium estimated the first source products to arrive on the market in ~18 months.

Does it really mean that our market size for LE Audio will be $1Bn in 18 months? Not exactly.

We can only guess that there is a high probability that, in 18 months, both Google and Apple will support LE Audio respectively in Android 12 (September 2021) and iPhone 13 (October 2021).

However, those new devices launched with the latest Bluetooth hardware and software will represent just a portion of the overall smartphone market. In order to understand the market opportunity for LE Audio, we have to look at another figure: the renewal cycle of smartphones.

And if we really would like to be exhaustive, we also need to look at the renewal cycle of laptops, which are used daily by millions of people with headphones and speakers.

What does it mean exactly? That an average user is upgrading their iPhone every 4 years and their laptop every 5 years.

Concretely, it means that before having the entire iPhone user base supporting LE Audio, we need to wait an another 4 years, which brings us to the iPhone 17 (October 2025).

What about the Android ecosystem?

It may take even longer than that.

Let’s look at the OS distribution of Active Android users in 2019.

In May 2019, a bit more than 6 months after its introduction, Android Pie (2018) represented only 10% of the active smartphone market. Among that 10%, we can assume that at least half of it is enabled through a software update and does not implement the latest hardware.

In order to reach at least 75% of the market, we need to go back to Android Marshmallow (2015) and include all the versions between Marshmallow and Pie.

If we assume that Android 12 (2021) will support LE Audio and that the distribution of Android will evolve consistently, we can then expect 75% of the Android smartphones to support LE Audio in May 2025.

Consequences

Over the next 5 years, LE Audio will just be a portion of the market. Relatively few users will be ready for LE only in the near-term: those renewing both the smartphone and the laptop in the same year

With a bottom-up approach, the LE Audio TAM is actually much smaller than anticipated. What’s the solution for people working on Bluetooth Audio? My conviction is that most of the brands will use “Dual-Mode” for the next 5–7 years.

What is Dual-Mode? A combination of Bluetooth Classic, and Bluetooth Low Energy Audio. Supporting both versions of the protocol during this period of transition.

How will it work? Your Bluetooth audio device could automatically detect which source is connected and what protocol is supported and choose the right architecture accordingly.

Why do I think that? Because I don’t know a lot of audio companies who would deliberately choose to reduce their Total Addressable Market (TAM) just for the sake of innovation.

Remember that investor I met 4 years ago?

He actually ended up investing in Tempow and is now one of my good friends and advisors. Was he convinced by our TAM back then? I don’t think so. But he made a bet on our team and on our capacity to grow as a company. We pivoted Tempow two years ago when we started working on True Wireless Earbuds, and I don’t think anyone is questioning our TAM anymore!

Unfortunately, large companies cannot be that agile, and I would definitely advise any company exploring the Bluetooth audio opportunities to carefully look at their TAM and see if it aligns with where the technology and the market are going.

The vain battle: Bluetooth Low Energy Audio vs Bluetooth Classic was originally published in Tempow on Medium, where people are continuing the conversation by highlighting and responding to this story.

In the (short) history of Tempow, there are a few exceptional moments that have come to reshape our company. One of these moments was when I tried a pair of Apple Airpods for the first time. The year was 2017.

At the time, my company Tempow was working on a breakthrough in Bluetooth technology. We were building a product that could connect one smartphone to multiple Bluetooth speakers from different vendors simultaneously. A challenge that had yet to be solved — it’s actually a lot more complicated than it sounds!

Meanwhile, Apple was busy creating the Airpods.

I’ll never forget when I tried them out for the first time: blown away. Almost immediately, I realized that these tiny products were setting the bar for a new category of products that would become massive in the years to come.

The engineering and development that went into making the Airpods was so sophisticated in fact that competitors have been scrambling to catch up ever since.

A couple of weeks later, we decided to pivot the company from Bluetooth speakers to True Wireless Earbuds (TWE).

Since then, the True Wireless Earbuds market went from nonexistent in 2016 to 90 million units sold in 2019 and on track to reach 300 million units by 2022.

Here are some of the ways True Wireless Earbuds are winning the consumer electronics and notably the hearables market and why they will continue to expand in the years to come.

We’re just at the beginning of what’s possible with voice control.

Current applications of smart speakers are pretty basic and we still haven’t started using the voice assistant like a personal assistant.

The earbud is the perfect device to become the link with your assistant.

My guess is that Google may be leading this evolution from voice to personal assistant with the Google assistant being more and more on the edge and meant to be used to navigate within Android (open/close apps, read notifications, etc.).

However, I believe the market is missing the target when it comes to bringing a personal assistant to your earbuds: everyone is trying to reuse what’s been developed for the smart speaker market and embed it into an earbud. But an earbud is not a speaker.

Your smart speaker is a family device, almost another person in your home.

Your earbud is a personal device, almost a part of yourself, an extension of your ears.

There are two challenges that should be addressed to evolve your earbud into your personal assistant:

1. The current “wake word detection engine” (“Alexa” or “Ok Google”) won’t work with the earbuds. Something needs to be solved around the assistant trigger so that you don’t have to address yourself to think out loud.
2. The second challenge is that the assistant for earbuds needs to be bidirectional and not unidirectional like a smart speaker. Your earbud assistant needs to be able to talk to you without you asking specifically. And the “assistant notification” question has still yet to be solved.

There is a convergence happening between the hearing aid industry and the audio industry.

We will soon see the first generation of earbuds which will never leave the ears, like a hearing aid.

It may happen with the earbud form factor. By embedding your earbuds with a hearing enhancement, you could experience augmented hearing or noise-canceling abilities. And some companies are already working on it, like this one, Mimi.

It may also happen with the hearing aid form factor (i.e. as invisible as possible). I listened to music using an “invisible” hearing aid from Sonova and I was bluffed by the audio quality while listening to music — it was excellent.

In both scenarios, augmented hearing or enhanced hearing abilities could soon be integrated in your TWE and could be leveraged in a range of ways from emergency first responders to announcements made on the intercom in public transit.

Conversely, noise-canceling also becomes very interesting in cases where better filtering sound and potentially increasing the volume for some specific sounds is important (like the cry of a baby).

The next generation of personal health devices will come from the ear, not the wrist.

If you have a personal health device then it’s likely worn around your wrist. But your ear is actually a very interesting touchpoint to collect health data (like body temperature) and particularly data related to your brain.

There is a ton of research on this at the moment, and we see some of the first Kickstarter projects emerging like these here and here. Apple is also filing several patents at the moment on heart-rate tracking with Airpods and it’s only a matter of time before more sophisticated monitoring follows.

The next generation of personal health devices will come from the ear, not the wrist.

Battery Consumption is Still the Limiting Technical Factor Today

For all of the opportunities TWE presents, there is still a key challenge, the elephant in the room that manufacturers and brands are rushing to solve: battery consumption and processing power.

In order to realize all of these use cases, battery consumption must be reduced in order to bring additional components and innovation into the earbud.

From where will this innovation come from? At present, chip makers, smartphone OEMs, and audio brands are in an interesting stalemate.

When we pivoted Tempow in 2017, it was because we recognized this need for innovation in TWE. We had the team, the expertise in Bluetooth technology and even some of the patents needed to solve it…

So why not go for it?

Telink Semiconductor is first to join our exclusive partnership program for chipset manufacturers to use Tempow’s audio solutions, including an upcoming Audio LE solution.

LAS VEGAS, January 6, 2020: Tempow, creators of software-only solutions to enhance core Bluetooth protocol, today announced the release of a new Bluetooth Software Stack for hearables and speakers, with an early prototype of the freshly revealed Bluetooth LE audio norm. It is also opening an exclusive partnership program for chipset manufacturers to use Tempow’s implementation.

Telink Semiconductor, one of the world’s leading Bluetooth semiconductor companies, is the first to officially join the partner ecosystem, and has already started working with Tempow in order to bring Tempow-powered chipsets to market in 2020.

“We’ve been focused on creating new Bluetooth-enabled audio experiences for years, so we’re very well-versed in the technical challenges associated with building these kinds of products,” said Vincent Nallatamby, CEO of Tempow. “We’ve been wanting to work at the chipset level to gain more control of the protocol for some time now, so we’re excited to start that process by working with Telink to enable the best Bluetooth-enabled hearable solution possible.”

Tempow was one of just ten companies invited by the Bluetooth SIG to participate in the official launch event for the new norm.

“Tempow Stack provides a unique value proposition because it’s a complete, turnkey solution,” said Wenjun Sheng, CEO of Telink. “We believe that Tempow Stack will be a great complementary to Telink’s in-house stack and will help us better serve existing customers while growing our market share. The combination of Telink’s competitive low-power dual-mode Bluetooth SoC and Tempow’s innovative software solution will bring tremendous new value to our customers.”

The adoption of Bluetooth LE Audio norm will require a renewal cycle of smartphones, and the vast majority of devices will move to support both LE Audio and Classic for an extended period of time while the market transitions. Tempow is tackling this transitional challenge by developing a dual-mode solution that allows brands to move from Classic to LE Audio with almost zero disruptions to Bluetooth functionality. Tempow Stack will automatically determine which audio protocol needs to be used based on the device being connected.

Chipset manufacturers joining the Tempow Partnership Program will be able to use Tempow Stack to develop chips with the following benefits:

• Constant synchronization and sound stability between Speakers and Earbuds
• Increased battery life optimized for hearing devices
• Seamless device pairing
• Audio sharing between True Wireless Earbuds
• Multi-source sharing, allowing users to connect smartphones and laptops simultaneously
• New LE Audio Norm support in 2020

Tempow Stack is the latest addition to Tempow’s suite of Bluetooth audio solutions, which follows the launch of Tempow Audio Profile (TAP), a Bluetooth profile that enables any smartphone manufacturer to stream audio on multiple Bluetooth audio outputs simultaneously, which has been deployed with both Motorola and TCL through global partnerships.

Tempow Launches Partnership Program for Chipset Manufacturers and partners with Telink was originally published in Tempow on Medium, where people are continuing the conversation by highlighting and responding to this story.

This year, I decided to listen to my own advice (!) and we booked a suite a couple of months ago at the Venetian Tower.

In the past couple of weeks, we organized meetings with existing partners, active prospects & new potential partners.

Before the show even starts, I already see some immediate benefits in having a suite:

1. More qualitative meetings: being able to schedule 1hr meetings is a rare thing at CES. Having a comfortable meeting setup is allowing that, instead of the usual “I’ll come by your booth around 10 am” followed by a 15-min stand-up.
2. More meetings: transportation is always a nightmare between the different halls, and even between the different meeting spaces. This year we managed to squeeze on average 4 more meetings a day compared to last year.
3. Better demos: having a suite allows us to organize a stable demo zone. Consequently, we will bring some of our early (and less stable) prototypes. It becomes a perfect opportunity to present our product roadmap.

I think I may be one of the only people in the industry over-excited by CES. For us, it’s a tremendous opportunity to meet new potential partners, to close deals, and to explore some of our roadmap ideas.

Here are some data to conclude in this post:

• 5 people from Tempow at CES in 2020
• 55 meetings scheduled
• 20 with Chinese companies
• 22 with people we will meet for the first time
• 19 with top-management execs (VP-level or CTO)

I can’t wait!

See you next week,

Vincent

Crazy year for Tempow at CES! was originally published in Tempow on Medium, where people are continuing the conversation by highlighting and responding to this story.

According to EqualOcean, a leading Chinese tech media, and investment research firm, Tempow is among the fifty early-stage startups that are likely to conquer the microelectronics world.

Tempow among the fifty early-stage startups that are likely to conquer the microelectronics world! was originally published in Tempow on Medium, where people are continuing the conversation by highlighting and responding to this story.

Tempow is a research and design lab based in Paris, France, with extended operations in Seoul, Korea and Shenzhen, China, focused on pushing the limits of Bluetooth technology. Their first product, the Tempow Audio Profile (TAP) is an updated Bluetooth protocol allowing any Bluetooth chip to stream audio on multiple Bluetooth audio outputs simultaneously. It is a 100% software solution and works with any brand of Bluetooth speaker on any chip. Tempow has also been working in specific software solutions designed to expand Bluetooth capabilities for home theaters and smart home assistants — TAP TV and TAP Smart, respectively.

Meanwhile, the company has established global partnerships to bring its Tempow-enhanced Bluetooth to market, and now announced a new solution created specifically for True Wireless earbuds, named Tempow True Wireless (TTW). As Tempow explains, “unlike other solutions on the market, Tempow’s proprietary Bluetooth profile enables any smartphone manufacturer to design truly wireless, high-quality earbuds with both buds being connected directly to the smartphone to deliver an exceptional user experience.”

True Wireless earbuds are currently one of the top product categories in the headphone market both in terms of volume and price, with several brands increasing their efforts to launch their own devices to compete with Apple’s Airpods. “Several smartphone companies have tried to compete with Apple on true wireless earbuds — Samsung with its IconX, Huawei with its Freebuds, Google with its Pixel Buds and countless others — but they’ve all fallen short on delivering an exceptional listening experience due to poor audio quality and stability,” the company explains. “Until now, no other company has been able to replicate the Airpods’ user experience because Apple has created a closed ecosystem with both hardware and software under the same roof — an inherent advantage over companies that focus exclusively on hardware and outsource software.”

As Tempow details, other than TTW, there are only two ways to power wireless earbuds with Bluetooth. The first is to create a chained connection between the sound source, the first earbud and the second earbud, which requires either a non-standard Bluetooth link (such as Qualcomm True Wireless Stereo) or a Near Field Magnetic Induction (NFMI) link. The second is Apple’s solution, which connects the first earbud to the sound source through a classic Bluetooth audio link (A2DP) and then requires the second earbud to sniff the first data link. This is only compatible with its Airpods, which inherently limits product diversity in the consumer marketplace.

“There’s absolutely no reason that only one company should be able to deliver an amazing wireless earbud experience,” says Vincent Nallatamby, founder and CEO of Tempow. “In many ways, we are thankful that Apple took the first step in showing the world the possibilities of Bluetooth-enabled wireless earbuds, but we believe our solution can democratize the experience and help other companies push the boundaries even further.”

As the company confirms, the new Tempow True Wireless solution doesn’t require any retransmission of data between earbuds and saves substantial bandwidth, permitting the use of high-fidelity codecs such as LDAC or HWA for improved sound quality, and reducing the audio-video latency for gaming and watching video on mobile devices. This, while allowing to extend battery life by up to 50 percent — one of the critical factors in the design of true wireless earbuds.

Tempow designed TTW to work seamlessly with any smartphone embedded with its core technology, leveraging its Tempow Audio Profile (TAP), which allows the device to stream the same sound source to multiple speakers. This makes Tempow’s technology more accessible than other solutions because any smartphone manufacturer can use it, and it only requires a classic Bluetooth chipset. “TTW is completely hardware agnostic, works with any smartphone, with any chipset, and is not cost prohibitive for hardware manufacturers,” they add.

We are proud to announce that Tempow will be attending to the 2019 Audio Engineering Society International Conference on Headphone Technology, gathering scientists, developers and practitioners who are involved in theory, technical design, application or evaluation of headphone technology.

Our CTO, Thomas Girardier, will be presenting a scientific document intituled “Comparison of Radio Power Consumption of True Wireless Earbuds.

True Wireless Earbud first appeared on the market in mid-2016 and since became one of the trendiest products in the audio industry. All True Wireless Earbuds use the Bluetooth protocol and the Advanced Audio Distribution Profile (A2DP) to connect to an audio source (smartphones, computers, etc.) but different approaches have been developed to allow both earpieces to get the audio data.

Our study models and compares audio streaming radio power consumptions of Bluetooth true wireless earbuds technologies based on a transmitting and receiving durations, and gives more concrete information concerning radio power consumption and overall power earpiece consumption.

Thomas will be present from the 27th August to the 29th.
