Remember a little while ago I told you about some underwater MP3 players I’ve been testing in time for the summer? Well now they’ve been published on Tech Radar here.

Personally I prefer the Finis design (pictured above) which you don’t have to put in your ears – it uses bone conduction technology to transmit the audio across your cheekbones.

It’s more comfortable to wear and doesn’t move out of position which can be a problem if you are wearing earbuds. The downside is that it’s a little more expensive than some of the others at around £80 (see here).

Most of the designs work surprisingly well underwater providing you give them a bit of a clean after swimming. I recommend a spray like Muc Off to get rid of any excess water and for cleaning out the charging points which can become corroded over time.

One question that people always seem to ask me about these devices is ‘can you listen to audiobooks on them while swimming?’ The short answer is no. Many people have tried but most report disappointing results when listening to dialogue.

However, for music these devices are great and some of them are very cheap (not much more than £25). Although I would definitely recommend the Finis, it can only be used in the water – it’s not suitable for land use. If you want something that can be used for running or cycling, then perhaps look at a model like the i360 instead which does both jobs very well.
