Open-Ear Air Conduction Design

The Logitech G9 uses air conduction to deliver audio without covering the ear canal. Weighing 28 grams, it stays in place with a silicone ear hook and a 360-degree bending memory wire. This design keeps the user aware of surroundings during office calls, running, cycling or driving.

Detachable DSP Noise-Cancelling Microphone

A magnetic boom microphone rotates 360 degrees for optimal voice pickup and removes when not needed. DSP noise cancellation suppresses background sound for clearer calls. The 15.4 mm driver provides louder, more detailed output during extended meetings or music sessions.

Bluetooth 5.4 Multipoint Connection

Bluetooth 5.4 supports multipoint pairing with two devices simultaneously. The 150 mAh battery delivers 12 hours of working time and recharges in one to two hours via USB Type-C. Range and stability follow the Bluetooth 5.4 specification under typical indoor conditions.

Questions about this item

Will the 98 dB signal-to-noise ratio keep audio clean during all-day use?

The headset specifies a 98 decibel signal-to-noise ratio for both headphones and microphone, which indicates low background hiss during extended sessions.

Does the headset need a USB-C port on my laptop to charge the 150 mAh battery?

Yes, the system requirements list USB Type-C for charging the built-in 150 mAh battery, which takes roughly 1 to 2 hours.

Can I pair the headset via Bluetooth 5.4 while still using a wired USB headset on the same PC?

Bluetooth 5.4 operates independently of wired USB audio devices, so both can be connected simultaneously without conflict.
