Let’s face it – Bluetooth audio sucks; it’s unreliable, static-y, and doesn’t fer multi-stream listening. That’s all about to change with the newest Bluetooth audio standard.
The Bluetooth wireless standard is celebrating its 20th anniversary in 2020. Now Bluetooth is shaking things up with a new standard, announced at CES 2020.
The new standard is an LC3 audio codec for delivering high data rates using less energy. It also includes a much-needed feature – multi-streaming audio support.
Currently, devices like our smartphones can only stream audio to one earbud in a wireless set. That means the earbuds then connect wirelessly to the second earbud to create stereo sound. This setup introduces dropouts, lag, and between wireless earbuds.
Bluetooth LE audio with multi-streaming audio support changes how the source device can connect. That means both wireless earbuds can receive a signal from the phone. It eliminates wireless earbuds from needing to manage synchronization themselves, rather than device.
Ideally, it would also improve the stereo sound quality and switching between Bluetooth audio sources. Another benefit the new standard is Bluetooth broadcast audio.
Broadcast Audio builds on top multi-streaming audio support to allow the transmission sound to multiple devices. That means you can share your music with a friend using their Bluetooth headphones.
The other significant change introduced with Bluetooth LE audio is the LC3 . LC3 features improved sound quality over the current SBC codec. It also uses a lower data transmission rate, which reduces the power required to operate.
The result could be a radical shift in how wireless earbuds are designed. It could significantly increase battery life in true wireless earbuds if the current battery capacity stays the same. Keeping the existing standard battery capacity may help manufacturers shrink the size wireless earbuds.
The final specifications for Bluetooth LE audio are still under work. Hardware that supports the new standard will be available in the second half this year. We could see new Bluetooth LE audio in time for the all-important holiday shopping season.
