Noise-Cancelling Bi-Directional Microphone: The rotating boom mic uses a bi-directional polar pattern to reduce ambient background noise from the sides, keeping voice capture clear during calls in noisy environments such as open-plan offices and home workspaces.
30 mm Fine-Tuned Audio Drivers: The 30 mm drivers cover a 20 Hz–20 kHz frequency range for full-spectrum audio reproduction across voice calls, music, and video content. At 32 Ohm impedance and 94 dBV/Pa sensitivity, they deliver consistent volume output at USB power levels.
Inline Volume and Mute Controls: The in-cable controller provides volume-up, volume-down, and mic mute buttons without requiring the user to reach for on-screen controls or navigate the host application. This keeps call management immediate and uninterrupted.
USB-A Plug-and-Play: The H390 connects to any USB-A port on Windows, macOS, or ChromeOS and activates immediately as an audio device without driver installation. The USB connection also powers the headset directly — no batteries or charging required.
Leatherette Padded Earcups and Adjustable Headband: Swivel-mounted leatherette ear cushions conform to the shape of the ear and reduce pressure during extended wear. The adjustable headband accommodates a range of head sizes without tools or complex fitting adjustments.
Plug-and-Play USB-A Connection: The H340 activates as an audio device immediately on connection across Windows, macOS, and ChromeOS — no software installation, no driver download, and no pairing process required. It works with all major VoIP and video call platforms including Teams, Zoom, Skype, and Google Meet.
Bi-Directional Noise-Cancelling Microphone: The rotating boom mic uses a bi-directional polar pattern to reduce ambient side noise while focusing on voice from front and rear. The boom tucks inside the headband when not in use, keeping the headset tidy during passive listening.
Stereo Digital Audio via USB: USB audio bypasses the host device's onboard sound card, delivering consistent digital stereo output independent of the quality of the integrated audio hardware. The 20 Hz–20 kHz frequency response covers the full audible range for both voice and music content.
Lightweight at 100 g: The H340's 100 g weight reduces headband and ear pressure during extended wear. Swivel-mounted foam earcups conform to the natural ear position and distribute contact pressure evenly across the outer ear.
Tuckable Boom Arm: The rotating microphone boom folds back into the headband when not needed, reducing visual bulk and preventing accidental contact with the microphone during non-call use.
Native USB-C Connection — No Adapter Required: Plugs directly into USB-C ports on modern laptops, MacBooks, tablets, and Chromebooks. This removes the adapter dependency that affects USB-A headsets on current-generation devices and simplifies deployment on USB-C-only hardware.
30 mm Fine-Tuned Drivers: Deliver enhanced digital stereo audio across the full 20 Hz–20 kHz frequency range for meetings, music, and video content. USB audio routing bypasses the host device's onboard sound card for more consistent output quality across different computers.
Bi-Directional Noise-Cancelling Microphone: The left-side rigid boom arm positions for optimal voice capture and uses a bi-directional polar pattern to reduce lateral ambient noise. The rotating boom tucks inside the headband when not in use, keeping the profile clean during passive listening.
Inline Volume and Mute Controls: The in-cable controller provides volume-up, volume-down, and mic mute without navigating on-screen menus or calling application interfaces. This keeps call management immediate and available at any point during a session.
54% Post-Consumer Recycled Plastic: Body components use certified post-consumer recycled plastic, and the FSC-certified paper packaging supports responsible forest management. The product carbon footprint measures at 4.78 kg CO₂e, offset to zero.
Laser-Tuned Drivers with Built-In Equaliser: The hardware EQ tunes the audio output for balanced reproduction across the 20 Hz–20 kHz frequency range. This produces more accurate and detailed sound for both voice calls and music playback compared to untuned drivers at this price tier.
Bi-Directional Noise-Cancelling Microphone: The right-side boom mic uses a bi-directional pickup pattern to reject ambient side noise while capturing voice clearly. A flexible boom arm adjusts position for optimal microphone placement, and the boom tucks inside the headband when not in use.
On-Ear Volume and Mute Controls: Controls on the right earcup handle volume adjustment and microphone muting without requiring a free hand to locate a cable controller. The mute indicator LED on the cord confirms active mute status at a glance.
Lightweight Design at 120 g: At 120 g — significantly lighter than the H390's 197 g — the H540 reduces headband pressure during extended wear. A padded leatherette headband and swivel-mounted earcups adjust to the head and conform to the ear shape throughout the day.
Flat, Tangle-Resistant 1.8 m Cable: The flat cable design resists knotting in bags and across desk surfaces. At 1.8 m, it provides enough reach to stand and move slightly from the desk without pulling the headset free.
Bluetooth 5.2 with Multipoint: Connects to two devices simultaneously and switches audio between them automatically during calls. A 30 m wireless range covers large rooms and open-plan workspaces without dropouts.
40 mm Drivers — 20 Hz to 20 kHz: Larger 40 mm drivers deliver full-spectrum stereo audio with rich bass, clear highs, and low distortion across both voice calls and music playback — a meaningful step up from the 30 mm drivers found in wired USB headsets at this price tier.
Flip-to-Mute MEMS Microphone with Beamforming: Dual omni-directional MEMS microphones with directional beamforming and DSP capture voice clearly while reducing ambient background noise. Flipping the boom into the headset body mutes the mic automatically — no software action required.
18-Hour Talk Time / 20-Hour Listening Time: The 400 mAh built-in Li-polymer battery powers 18 hours of talk time and 20 hours of music listening on a full two-hour USB-C charge. A five-minute quick charge provides approximately one hour of use.
Memory Foam Fabric Earcups with On-Ear Controls: Fabric-covered memory foam ear cushions reduce clamping pressure during extended wear. Earcup buttons handle volume, play/pause, call management, and Bluetooth pairing — keeping all controls within natural reach without touching the connected device.
