Thunelec U9 Bluetooth 5.4 Earbuds

These true wireless in-ear headphones combine active noise cancellation with a multifunctional touch screen on the charging case. They suit commuters and office workers who want cable-free audio and quick access to controls without unlocking a phone. The IPX7 rating makes them viable for sweaty workouts or rainy journeys.

48-hour total playback with 1.5-hour case charge

Each bud runs for up to 6 hours on a single charge and the case extends listening time to 48 hours. A full case recharge takes 1.5 hours. The 45 dB ANC and ENC dual-mic system blocks up to 90 % of ambient noise, though battery life will shorten when cancellation is active.

Upgrade from basic buds lacking ANC

The jump is worthwhile if you regularly fight background noise on trains or in open-plan offices and want to adjust EQ modes or volume directly on the case. Buyers who need multi-point pairing or wireless charging should look elsewhere, as neither feature is included.
