The Jabra C820s remove background noise by up to 22 decibels, the manufacturer claims.

They are powered by a single AAA battery in the ear cup and come with a standard stereo audio cable for devices such as MP3 players or PCs.

There is also a connector cable for music phones with adapters, an airline adaptor and a 3.5mm – 6.5mm stereo adaptor.

They can be folded flat into the supplied case to minimise damage when traveling, and weigh less than 200 grams, making them ultra-portable.

The C820s carry a recommended retail price of $159. More information on the product is available at www.jabra.com
