White J51 earbuds with Bluetooth 5.4

These true-wireless in-ear headphones use Bluetooth 5.4 for stable pairing and automatic reconnection. A 13 mm dynamic driver in each bud delivers stereo sound with passive noise isolation. The charging case provides up to 32 hours of total playback and recharges in 2 hours 10 minutes. Touch controls handle music, calls and voice assistants without a cable.

Suits commuters and gym users who want lightweight

The 30 gram weight and IP7 waterproof rating make them practical for daily travel and sweaty workouts. Buyers who need active noise cancellation or a wired connection option should consider other models. Single-ear use is supported for calls or situational awareness. The 15 metre wireless range covers typical room-scale movement.

32 hour total battery life from the case

This figure determines whether the earbuds last through a full work week without plugging in. Each charge cycle restores the case in 2 hours 10 minutes via USB-C. The 13 mm driver size and Bluetooth 5.4 version are fixed hardware traits that cannot be upgraded later.
