The NW-WS413 is an improvement over the prior model NWZ-W273. All buttons are easier to press and give more tactile response. The docking contacts on the headphones are raised so they make a better connection to the docking station, which was sometimes a problem with the prior model.

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 ....

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!

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 dont like wires on me when I workout in the gym and work too hard to carry a phone around. Ive tried many pairs of wrap-around headphones These fit super snug and dont pop loose. They also have great battery life. I think Ive charged them up once or twice in a month but that is just a precaution.

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.

some of my friends said the charger sometimes broken. but this mp3 players do look cool. many people like it. I suggest that it could be a little louder. Works well for music that no problem, but when I try to listen to books it's just too quiet.

easy to used

The Sony NW-WS413 is a 4GB MP3 player built into a set of waterproof and dust-proof IP67/68 headphones. There's also the NW-WS414, which are identical but bump up the storage to 8GB. Both models form part of the Sony Walkman NW-WS410 series. That's the simple answer.

Battery life; One hour of use from three-minute charge; Superb fit and weight; Waterproofing and dust-proofing

Need to swap earbuds; No Bluetooth option or mic; Expensive

As you'd expect from an all-in-one device, the NW-WS413 is rather large compared to a regular pair of Bluetooth headphones, but considering there's a whole MP3 player hidden inside it, it's really quite sleek given how much tech Sony's managed to pack in.
