If stumping up for the Oakley sunnies is out of the question, this pair will do the job and will cost far less to replace should they get damaged while you’re at the beach or on an adventure holiday.

There’s a 1GB flash memory, Bluetooth so you can use them with your mobile, a voice recorder and a car kit. You can play MP3, WAV and WMA music and the inclusion of Bluetooth means the attached earbuds can also be used to enjoy any tracks stored on a paired Bluetooth-enabled mobile phone or to answer calls from it. A voice recorder, car and mains charger are all part of the £55 kit. Charging takes three hours, with playback time nearing double that.
