Acefast did not add an external piece, nor did they create an additional accessory, but transformed the case itself into a dual-use component. Order the earbuds-stand!
A safe choice
The proportions are minimalist: each bud is small, rounded, with an in-ear profile that almost instinctively fits into the ear canal.
Audio performance
W4 delivers a surprisingly coherent soundstage for its price range: clear mids, warm voices, and a bass that makes its presence felt without drowning out the details.
Intelligible calls
The integrated microphone processes sound in real time to eliminate ambient buzz, wind, and other disturbances.
