Logitech H340 USB Headset with Noise-Cancelling Mic (981-000475) – Black
A plug-and-play USB-A headset with its own digital audio and a bi-directional noise-cancelling boom mic. 100 g on the head and a 1.8 m cable — the everyday call headset, without a battery to charge.
Quick Glance
Key Features
Noise-cancelling boom mic
A bi-directional noise-cancelling microphone on an adjustable boom, tuned 100 Hz to 16 kHz for speech and rated at −42 dBV/Pa. It cuts the office behind you out of what the caller hears.
Digital USB audio, no drivers
USB-A carries the sound as data and the headset does its own conversion, so it bypasses whatever sound card the machine has. It appears as a microphone and a speaker the moment it is plugged in — nothing to install.
Light enough for a full shift
100 g and 160 × 175 × 60 mm, with a 1.8 m cable that reaches a tower PC under a desk. A 20 Hz to 20 kHz response at 22 Ω input impedance.

Need-to-Know
- This is the USB-A model, part number 981-000475. A laptop with only USB-C ports will need an adapter or a dock — ask us if you would rather have a native USB-C headset.
- The noise cancelling is on the microphone, not the earcups. It improves what the caller hears; it does not block office noise for the person wearing it.
- Being USB, it only works with a computer. If the same headset also needs to work with phones and tablets, the analogue 3.5 mm H111 is the one to order instead.
Best For / Customer Benefits
Customer Benefits

- No battery and no charging dock — one cable, and the headset is always ready.
- Plug-and-play on Windows, macOS and ChromeOS, with Works With Chromebook certification for school and shared-device fleets.
