Wireless sport earbuds with IPX4 rating

The D-20 earbuds use Bluetooth 5.0 for stereo audio and hands-free calls. An IPX4 shell and internal nano coating resist sweat and splashes during exercise. The in-ear design with silicone gel tips stays secure while running or cycling. A built-in microphone and on-ear controls handle calls and playback without reaching for a phone.

For active listeners who want simple wireless audio

Suits gym-goers, runners and commuters needing sweat-resistant stereo sound and up to 8 hours of play or talk time. CVC 6.0 processing reduces background noise during calls. Not for buyers who want active noise cancellation that blocks ambient sound. Not for users who need a charging case to extend battery life beyond the single-charge rating.

8-hour continuous battery per charge

Delivers 8 hours of music playback or talk time on one charge and up to 400 hours on standby. The earbuds recharge via Micro-USB. No charging case is included, so total off-grid usage is limited to the single 8-hour cycle. Check that your device supports Bluetooth 5.0 before purchasing.

Questions about this item

What comes in the box and do I need to buy a charger separately?

The D-20 earbuds include a Micro-USB charging cable so you can power the case from any standard USB port without an extra purchase.

Should I choose the D-20 for sports or daily commuting?

The IPX4 rating and secure silicone fit are built for sweat and movement, making the D-20 a natural match for running, gym sessions or outdoor cycling.

Eight hours of music or talk time plus 400 hours on standby means most users can train several days before needing to recharge the case.
