YINGHUA i27 Bluetooth 5.4 Earbuds

These true wireless earbuds use Bluetooth 5.4 with dual-channel transmission for stable, low-latency audio. They support HSP, HFP, A2DP and AVRCP profiles and pair automatically when removed from the charging case. Touch controls handle music, calls and voice-assistant access without reaching for a phone.

Buyers wanting IPX7 waterproof sports buds

The IPX7 rating protects against sweat, rain and splashes during workouts or outdoor runs. Flexible earhooks and three silicone tip sizes (S/M/L) aim to keep each 7g bud secure. Users who need active noise cancellation, wireless charging or a smaller case footprint should consider other models.

54-hour total playback with 10-minute quick charge

The 400mAh case delivers up to 54 hours of combined listening time and recharges fully in 1.5 hours via Type-C. A 10-minute charge adds roughly 2 hours of playback, while the LED percentage display shows remaining case power at a glance.

Questions about this item

Do I need a device that supports Bluetooth 5.4 to use these earbuds?

The earbuds use Bluetooth 5.4 and support HSP, HFP, A2DP and AVRCP profiles. They will pair with any device that offers Bluetooth audio, and the connection falls back to the highest version both sides share.

Will the earbuds stay connected if I move between rooms while my phone stays on the desk?

Bluetooth 5.4 with dual-channel transmission gives a stable link through walls at typical indoor distances. Range depends on building materials, but the protocol is designed for reliable coverage across a normal home.

How can I confirm the earbuds are charging correctly after placing them in the case?

The charging case has an LED percentage display. When the buds seat properly the indicator shows the case battery level and each earbud’s charge status, confirming the connection is good.
