Open-ear bone conduction headphones

These gray headphones use bone conduction technology to deliver sound through vibration, leaving the ear canal open. The open-ear design maintains situational awareness for runners, cyclists and commuters who need to hear traffic and announcements. A 16 millimetre driver unit produces a frequency response of 5Hz to 20KHz with 91 decibel sensitivity and signal-to-noise ratio. Bluetooth wireless connectivity provides a 33 foot operating range.

Sustained workout performance

An IP68 rating protects the headphones against sweat, rain and accidental immersion during long training sessions. The internal battery delivers 13 hours of continuous playback on a single charge, covering multiple workouts or a full workday. Recharging takes approximately two hours to restore full capacity. The 8 ohm input impedance and balanced tuning aim to reduce ear fatigue during extended wear.

Adjustable fit and setup

Earbuds slide along the frame to adjust contact pressure, letting the user trade volume for ambient awareness. The lightweight, ergonomic frame is designed for all-day comfort without clamping force. A 3.5 millimetre connector is included for optional wired use when Bluetooth is not desired. No active noise cancellation is present, so loud environments will still be audible.

Questions about this item

Does the open-ear design let heat build up around the ears during all-day wear?

The open-ear frame sits outside the ear canal, so air circulates freely and no heat is trapped against the skin during extended sessions.

What device and connector does the buyer need to pair these headphones for the first time?

A Bluetooth-enabled phone, tablet or computer is required; the 3.5 mm jack is provided only for optional wired listening.

Will the 16 mm bone-conduction drivers work alongside an older 3.5 mm audio source without quality loss?

Yes, the 3.5 mm connector accepts legacy players directly, while the 16 mm drivers deliver the same open-ear response whether the signal comes from Bluetooth or the cable.
