Compact Wireless Earbuds for Active Use

Weighing 10 grams, these in-ear headphones use Bluetooth 5.3 for a stable link up to 10 meters. An IPX7 rating and interior nano-coating protect against sweat and rain during workouts. The package includes four eartip sizes, a carry bag, a Micro USB cable, and a wire clip.

Suited for Sports and Daily Commuting

On-board buttons handle volume, playback, track skipping, calls, and voice-assistant activation without touching a phone. Battery life reaches 12 hours per charge, extending to 16 hours in typical use, with a two-hour recharge. Buyers who need active noise cancellation or a multi-earbud charging case should consider other models.

Battery Runtime Defines Daily Usability

The integrated cell delivers up to 16 hours of listening time from a single two-hour charge, while the phone screen displays remaining capacity. This single figure determines whether the earbuds last through a full day of exercise and travel without needing a top-up.

Questions about this item

How do I confirm the Bluetooth 5.3 connection is stable after pairing?

The headphones reconnect automatically to previously paired devices on power-on and maintain a 10 meter range. Audio and video stay synchronised with low latency, and the remaining battery level appears on the phone screen.

What accessories are included and is a charger supplied?

The box contains the earbuds, a carry bag, four pairs of eartips (XS, S, M, L) with M pre-installed, a Micro USB cable and a wire clip. A USB power adapter is not included and must be purchased separately.

Which eartip size should I choose for the best fit?

Four pairs are provided (XS, S, M, L) with medium already fitted. Try each size to find the one that seals comfortably in your ear canal for secure fit during workouts and optimal bass response from the dynamic drivers.
