Logitech USB Headset H340 Repair

The Logitech USB Headset H340 is a lightweight, wired USB on-ear headset designed for clear calls and everyday listening. It features digital stereo sound and a noise-canceling boom microphone that helps reduce background noise for better voice clarity. With a plug-and-play USB-A connection and an adjustable headband with soft foam ear cushions, it’s built for comfort and simplicity. The rotating mic boom can be positioned for speaking or moved out of the way when not in use.

The Logitech USB Headset H340 can be identified by the model number ("M/N") A-00044 (or part numbers, "P/N") 981-000474, 981-000475, 981-000476, 981-000477, 981-000478, 981-000500, 981-000507, 981-000508, 981-000509, 981-000714, 997-000359 depending on region, vendor, and color.

If the headset isn’t detected, try a different USB-A port, avoid USB hubs, and confirm it’s selected as the default input/output device in your OS settings. For mic issues, ensure the boom is positioned close to your mouth, check input levels and privacy permissions, and test on another computer to isolate the problem. Rebooting and updating your OS’s audio drivers can also resolve recognition or audio quality issues.
