I don’t do voice chats on Deck. But when I only have a short time to play, I just use standard Apple earbuds that I’ve had for years.

When I get to game for more than an hour and feel like gaming on the couch, then I use my JBL Quantum TWS earbuds with the USB C adapter. These are primo ear buds, incredibly low latency, sound excellent, and are immersive with the noise canceling and noise isolating. Built in microphone, but I don’t use it for that purpose. I’d imagine for the price point the mic quality should be somewhere between good and great, depending on preference.
