It's been four months and the botton given to change the track has been not functioning properly ....even my computer is not recognizing the device since quite a few days ....even the battery life has gone down to 4 to five hours ....

Before this product I was using my iPod nano with the apple ear buds. I could hear all the background noise in the gym. The first time I used the Sony, all that noise disappeared!! So much easier to concentrate and stay focused in the gym!! Awesome product!!

I love this Walkman MP3 payer! Only one problem, there was no comprehensive instruction manual with it. I had to spend time to find it on line. The manual is not easy to understand. Once I figured it all out, it was all pleasure. The sound is crisp and clear. Not muffled.

These swim-pods are GREAT. They are simple to use and download your own music (200) and crystal clear sound. I use mine everyday when I swim. I have tried several others just work as good as these. They are ranked #5 on the best swim earbuds. The cost was fair but they work great for me.

Music is crystal clear. I am swimming longer and stronger.

Bought these 2yrs ago, and now I cannot control the sound. I either have it to loud or no sound at all.

I love these headphones. I use them everyday in the gym. They make my morning swim amazing. I have loaded them with an audio book and I love being able to learn while I swim. I also use them after in the jacuzzi, sauna and shower. Best investment.

Simple to load via PC. Earpieces are comfortable and secure even during aerobic workout. Comes with waterproof and standard ear moulds in 3 different sizes.

The Sony Walkman NW-WS413 is a go anywhere all-action MP3 player that doubles up as a pair of waterproof headphones

I found these initially tricky to set up via the computer which took some time. The controls are very small and fiddly. However they work really well and have so improved my swimming sessions. No more boring lengths!
