Sportwrap Headphones £49.95

There are plenty of underwater MP3 players on the market, but it can still be a hassle to upload your music to them when you already store all your tunes on an iPod. That’s where this waterproof case comes in handy, allowing you to take a fifth generation iPod Nano into the pool. It clips on to your swimwear, and allows you to operate your Nano like you would normally. The Sportwrap headphones come separately. The sound quality isn’t as good as on dry land, but on the whole it does a good job of motivating your swim workouts.
