Samsung now allows its Galaxy Buds 2 Pro to be used as binaural microphones to record 360-degree sound. However, this feature is related to certain smartphones only.

Like all wireless headphones, the Samsung Galaxy Buds 2 Pro have microphones so you can not only make calls, reduce ambient noise or record videos using the headphones as an audio source.

However, Samsung has decided to go a step further with its wireless headphones. According to the site 9to5Google, the Korean manufacturer has decided to roll out a new function for its wireless headphones allowing them to be used as true binaural microphones. This type of microphone will allow listeners who would later listen to the recording through headphones, or using headphones, to feel the recorded sounds as if they were heard directly from their surroundings, since the microphones are placed at the height of each ear with a perfect restitution of spatialization.

Required support for Bluetooth LE Audio

However, this feature is limited to a few high-end Samsung smartphones that take advantage of the One UI 5.0 interface and Bluetooth LE Audio support. This is already the case with the Samsung Galaxy Z Flip 4 and Galaxy Z Fold 4, and it should also be the case with the Galaxy S23 when they launch. To take advantage of this feature, Samsung Galaxy Buds 2 Pro owners can update their camera app to discover a new feature called “360 audio recording“. This limitation to only a few Samsung smartphones is explained by the necessary support for Bluetooth LE Audio for sound transmission from the headphones to the smartphone. In fact, the classic profile used by Bluetooth headphones strongly compresses the audio transmission from earphones to smartphone.With Bluetooth LE Audio, streaming calls or recording audio is now done using the LC3 codec – just like listening to music – and therefore allows much better quality sound files to be recorded .

As a reminder, the Samsung Galaxy Buds 2 Pro are not the first headphones to offer binaural sound recording. In 2018, Sennheiser launched the Ambeo Smart Headset wired headphones, equipped with large microphones on the back of the ears to enable 360-degree sound recording.
