The headphones market is booming as MP3 players and smartphones allow music on the move.
Unfortunately, the earphones bundled with a phone or music player don't tend to be very good – even the Apple EarPods. So if you really want to make the most of your tunes, we'd recommend upgrading.
The good news is you don't need to spend a fortune for good sound. Some of the best headphones around can cost hundreds of pounds, but there are plenty of earphones under £50 that represent brilliant sound-per-pound value.
