AirPods Pro 2 to deliver higher quality Bluetooth codecs

Apple recently made available the new beta firmware of AirPods along with the first builds of iOS 16 and other upcoming operating systems introduced during the WWDC 2022 keynote.

Now, a developer has been able to confirm that the beta version of the AirPods Max can support a higher quality Bluetooth codec, which, at least, will improve the voice call quality of Apple’s premium headphones and could preview the coolest features. coming to AirPods Pro 2.

As posted by the Twitter user George (through Shrimp Apple Pro), has enabled the LC3 codec for AirPods Max via its beta firmware. For those unfamiliar with it, the LC3 codec is the future low-power, high-quality Bluetooth codec coming to headphones soon.

The low complexity communication codec – LC3 for short – will be able to transmit at much lower bitrates without losing the audio quality we currently see with the Bluetooth standard.

In this case, as shown by the Twitter user, the LC3 codec will improve audio calls, making them sound better, but the true potential of this technology will need Bluetooth 5.2 and a new generation of AirPods hardware.

AirPods Pro 2 to support low energy audio technology

While the LC3 codec will improve audio calling, efficiency and stability of Bluetooth devices, the requirements to take full advantage of this standard will require Bluetooth 5.2, which no AirPod has.

9to5Mac sources confirm that the next generation of AirPods Pro – codenamed B698 – will feature the next version of the H1 chip, Apple’s audio processor, which may be able to handle this technology.

Furthermore, 9to5Mac already found references on iOS 16 which will support LC3 codec and low energy audio support. For LE Audio support, it is worth mentioning that a senior Apple engineer is heavily involved in this new standard.

While we can’t confirm support for lossless audio via Bluetooth, as reported by analyst Ming-Chi Kuo earlier this year, we can say that the audio experience on the AirPods Pro 2 will improve a lot.


With Bluetooth 5.2 and LC3 support, Apple will be able to get rid of AirPods that sync when in the user’s ears and improve battery life thanks to the low-power standard, focusing on efficiency and stability.

It is important to note that shortly after the WWDC 2022 keynote, the Bluetooth association announced Auracast Broadcast Audio technology, also known as Augmenting Reality Audio Broadcasting, which will enhance existing experiences on AirPods while unlocking new possibilities.

For example, with Auracast you can listen to songs, watch movies and more, with multiple wireless headsets connected at the same time. Currently, you can only connect up to two AirPods from the same source.

When it comes to lectures and audio guided tours in museums, you can connect your iPhone and AirPod to a source and listen to the guided tour, lecture, etc.

More rumors about the upcoming AirPods and the future of “Lossless Bluetooth”.

Analyst Ming-Chi Kuo says the new AirPods Pro 2 will still come with a Lightning charger. Additionally, rumors are talking about a new form factor and health and fitness tracking functionality, as Apple itself has anticipated that AirPods may someday complement the Apple Watch’s health tracking capabilities by offering additional data points.

At the end of the day, if you combine all of these technologies, we will likely have a better music experience, but, at the moment, it’s impossible to say whether Apple will introduce the long-rumored “Lossless Bluetooth” support that other companies have said they are working on, such as Qualcomm. and Sony.

What we can say is that to take advantage of all these technologies, new hardware will be required and AirPods Pro 2 will be the first to present this novelty.
