Harman Kardon is a well-known brand, and the CL over-ear headphones are testament as to why. It's all about quality: right from the eye-grabbing aesthetics through to the ear-cushioned audio experience. Industrial yet elegant, they may not be to everyone's tastes, but we like the raw look as much as the balanced audio. However the not traditionally adjustable headband and flat ear cups aren't especially comfortable for long periods of wear, and we feel that there ought to be a pinch more top end for a more complete listen. Still, we're impressed overall.

The BDS 477 system itself is lovely to use with a rather stylish remote, and the comprehensive specification impresses. **** (4 stars)

The BT is a handsome bit of kit. The square earpads and steel headband are lovely design touches and it feels very well assembled. […] Sonically, the BT is very capable too.  Very recommended! 4 stars and a half verdict.

Bluetooth cans with comfort. The BT's performance is very good indeed, bringing both impressive high-frequency detailing and war, enjoyable bass to the party. […] Equally impressive is the design and build.

Build quality is excellent, with an eye-catching cylindrical design and classy gloss finish, while setup is a total cinch.

Undeniable alluring product!

There is a great deal to like about the BT. Harman Kardon has created a superb piece of industrial design that manages to deliver sonically as well. […] On a purely subjective level, they are a pleasure to use.

With its SB 30, Harman Kardon takes a big stride towards a grand home cinema experience.

A fresh and unique option for the discerning music fan on the move, according to What Hi-Fi? Sound and Vision that gave the headphones a 5 stars review

An in-line mic and control buttons make them smartphone friendly, while the rechargeable battery keeps you bumping in a wireless style for up to 12 hours- you can plug in a cable after that.
