Sundara Closed-Back are a new closed-back version of the acclaimed Sundara Planar Magnetic Headphones, by HiFiMan.

Featuring hand-assembled wood-grain beechwood ear cups, which offer the benefit of exceptional sound and stylish good looks, Sundara Closed-Back delivers a huge soundstage with low levels of ambient noise and an all-enclosing immersive audio experience.

Making use of HiFiMan's NEO Supernano Diaphragm (NsD), which is now 80% thinner than more common headphone diaphragms, resulting in fast response times and full-range, detailed sonics.

In addition, the so-called acoustically invisible stealth magnet technology significantly reduces reflections and diffraction that can have a negative effect on sound quality. The net result is a dramatic improvement, compared to traditional rectangular magnets of other Planar headphones.

Supplied with detachable dual-sided 3.5mm cable, plus 6.35mm adaptor for connection to a wide range of source devices out of the box.
