Open Ear Design

No Sew X18 headphones use an open ear form factor that rests outside the ear canal. The 14.2 mm driver unit delivers a 5 Hz to 20 kHz frequency response with 21 ohm input impedance. Bluetooth wireless connectivity provides a 10 metre signal range. A charging case is included for storage and power.

Suited for Outdoor Activity

The IP54 rating protects against dust and water splashes during running, cycling or workouts. Weighing 63.7 grams total with each earbud at 8 grams, they stay light for long sessions. Open ear coupling lets you hear traffic and conversation while listening. Swimmers or users needing full noise cancellation should look elsewhere.

36 Hour Battery Life

The integrated battery delivers up to 36 hours of operating time on a single charge. This figure covers combined playback and talk time using the supplied charging case. Buyers who require longer continuous use without recharging will need a different solution.
