In-ear headphones with 14.2 mm drivers

These wireless earbuds use Bluetooth 5.4 for a stable connection up to 15 meters. They are built for listeners who want immersive stereo sound and clear calls without a cable. The passive noise cancellation helps reduce ambient distractions during music or voice use.

Battery life and charging limits

Each earbud runs for 6 hours on a single charge. The included case extends total playback to 30 hours and recharges fully in 1 hour via Type-C. There is no wireless charging mentioned, so a cable is required to replenish the case.

IPX7 waterproof rating

The earbuds meet the IPX7 standard, meaning they survive immersion in water up to 1 meter for 30 minutes. This suits workouts, rain and accidental splashes. Buyers who need a higher dust or pressure rating should look elsewhere.
