    I swim laps about an hour or more and the music helps me keep my pace and pass the time. I changed the ear buds to a ridged set and that helped keep them in my ears and once that was done this has been a great product. I have found that none of the small round buds stayed in my ears so I have changed them on all my head sets

    Two stars due to lack of customer support and no support for WMA.
    I purchased this because it was advertised at the time as supporting WMA format audio.  After several attempts to load WMA files, I gave up and have been using it with MP3 files.  I''ve made several attempts to contact Fitness Technologies customer support. several emails, several phone messages, even tried to enlist the aid of Swim Outlet but all to no avail.  Fitness Technologies appears to have no customer support whatsoever.  
    They have since stopped advertising it as supporting WMA, but the manual on the Fitness Technologies web site still shows WMA as a supported format.
    In addition the headphones would not stay in me ear and seal out the water.  I replaced them with X1 Audio headphones and have had decent luck after about 9 months use.  Battery life is only about 3 hours.
    On the plus side, sound quality is good, it has been used 4-5 days a week for over an hour a day without any problems other than those already mentioned.  If you don''t mind buying a better pair of earbuds and lack of WMA support it is an okay product.

    The MP3 player was great, easy to down load music, fits perfect on my goggles, and light weight. BUT ear buds will go out and there are NO replacement buds, therefore that will make them useless! WHEN replacement buds are available then you should purchase.

    Positives: great training tool for endurance training. Light weight, attaches to goggles without adding noticeable drag, very easy to download music.

    Negatives: The headphones are garbage. It comes with different size ear buds but they are all crap. The only way to get a water tight fit is to use wax ear plugs and basically make a seal that way. I have only used them three times and already one ear bud is not working as it should.

    I wish I could return them but IDK if there is a better product without paying $150 plus

    Great sound, but difficult fit for the ear buds.  Clip awkward.
    I struggled and one ear piece stopped working before I ever got into the pool for my laps.  Will try to contact vendor/company.

    What a cool little invention!  The only problem is that it took a few trys with the earbuds to get a good fit with my ears where water didn't leak in.  Once I found a good fit I could swim all day.  Holds lots of songs and the battery lasts for a long time before it needs to be recharged.

    When I tried to load my music, I could only hear 4 songs.  The unit said I had my whole play list.  I tried both I tunes and media player.  This is the second different waterproof MP3 player I have purchased from you and none worked right.  The issues had nothing to do with being water proof but with the ability to function as a MP3 player.  there must be something out there that is a good player and waterproof.

    I used this everyday while swimming. I listen to books.It would be great if it started
    where it was turned off instead of going beck to the beginning of each chapter. Other then that , it is easy to load books on and has a good sound.
