My earbuds, a pair of Samsung Galaxy Buds 2, are a bit broken. The touch controls don't work like they used to, and I can't be bothered to figure out why. Of it, the only thing I miss is the ability to toggle the noise controls between Active Noise Cancelling and Ambient Sound. I used to be able to long press an earbud [1], but now I have to unlock my phone, go into the Bluetooth settings, and access the earbud-specific settings menu to switch the selected noise control.
Update from sometime in 2024: I realized that I deleted the Galaxy Wearable app at some point and that was what broke noise controls, grumble grumble why do we need another app to access hardware features...
