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. 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. 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. 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. Digital USB audio bypasses the machine's sound card, so call quality does not depend on what is fitted to the PC. The noise-cancelling boom mic is what stops callers asking people to repeat themselves in a busy office. 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. Connectivity: Wired USB-A.

Manufacturer Part Number: 981-000475. Suited to: Video meetings and VOIP calls; Contact and support desks; Chromebook classrooms; Home-working setups. Used by UAE offices, contact centres, video-meeting rooms and Chromebook classrooms needing a wired USB headset. Please note: 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. In the box: Logitech H340 USB computer headset; User documentation.
