Acefast Wireless Earbuds (W4) In ear TWS, BT v5.4, ENC Noise Cancelling, with Built in Phone Stand, IPX4, 350mAh Black

A safe choice

The prosthetics are minimalist: each bud is small, rounded, with an in-ear profile that fits almost instinctively in the ear.

Audio performance

The W4 delivers a surprisingly coherent soundstage for its price class: crisp mids, warm vocals and a bass that makes itself felt without drowning out detail.

Intelligible calls

The built-in microphone processes sound in real time to eliminate ambient hum, wind and other disturbances.
