Aune AC55 Open-Back Clip-On Headphones – 40mm W-Shaped Diaphragm, Hi-Res Audio

Meet the Aune AC55 open-back clip-on headphones, a versatile companion for home audio, portable players, and on-the-go listening. Built around a 40mm W-shaped bio-fiber composite diaphragm and a highly elastic long-excursion surround, the AC55 blends broad dynamic range with refined detail to reveal textures across your favorite tracks.

Open-back design paired with a high-dynamic symmetric motor system creates a sense of space and precise control. The result is a listening experience that feels natural and immersive, with bass that extends depthfully while mids stay clear, and treble that remains articulate across many genres.
