Pixel buds pro 2 and Windows 11
So, if you've ever tried using your buds for calls on Windows 11, I'm sure you've noticed they sound terrible on calls, such as teams. Looking around, the main issue is how Windows handles the Bluetooth audio, and the best you can get for the microphone is tape deck quality.
I've been hunting for a way to fix this, as I listen to music while I work and would rather not have to pop my buds out to take a call. The solution I found is a Sennheiser BTD 600 adapter. This isn't a Bluetooth adapter, but it has Bluetooth, and well essentially act as a sound card for you. While the buds do not have an aptx codec, it'll work with the standard Bluetooth codec. It takes no downloads or software to operate, works with teams, and will indicate mute, along with a button to mute calls.
Since the codecs don't line up, I was able to get FM quality on the microphone, double the standard tape deck quality. I've gotten no complaints with these as compared to my wired headphones. Not a perfect match, but close enough for calls. Plus, it also indicates teams notifications with the indicator lights.
I know creative has a dongle that works with le Bluetooth, but the ratings weren't as good and it doesn't advertise call functionality like the Sennheiser.
