    I bought this to keep me energized with music while working out in the pool. No problem loading tunes and all was right in my world...until the earbuds started cutting out, or totally losing connection...  No big deal I thought...just get a new pair of earbuds.  BUT NOOOOoooooo!  There are no earbuds for sale.  I have to replace the entire unit if I want new buds.  I got about 8 months out of this before it became a nuisance.  Think twice before you buy....  If there is one out there that works and has replaceable buds, please post.  I need something to keep me going :)

    I use the mp3 player for swimming lanes. It works really well so far - but I wish the earphones would stay in better (they tend to come out when swimming) and once you get any water in your ear it is harder to hear the sound from the mp3 player. Some type of waterproof headphones that went into the ear better would make the product a 5 star. Easy to load up with music, clips to goggles and batter lasts

    I have used the device exactly twice since it arrived. The first time I used it, within the first few minutes of exercising one of the ear pods lost sound completely. I got the same results the second time I tried it. I'll give it one more shot, if I have the same results, I'm sending it back.

    Love at first sound, I was the envy of the pool..a better workout, more fun..but then the earbuds started to get static and within days simply died.  I'm embarrassed because I bragged to fellow pool members that they were so great and to buy one and then they disappoint. I now told everyone to NOT buy..  Guess what else tho?!  There are NO earbud replacements available.  So save  your money and don't buy this device.

    I use the player 45 minutes to an hour 5 days a week for lap swimming.  Player itself is fantastic with great sound and storage.  Headphones however are subpar at best.  Sound cuts out in the left bud quite a bit.  Sent an email to the manufacturer but have never received a response.

    This is easy to use.  The instructions are clear. I only wish the clip was a bit sturdier.  I like to clip it to the strap on my goggles.  The picture shows it clipped to a swim cap which is really thin.

    I use my MP3player 4 times a week while swimming laps.  It rocks!  It has made lap swimming so much more enjoyable.  I also plan on using it for walks and during water aerobics. It is easy to use while swimming and sounds great!  I wish I had gotten one sooner.

    The headphones died almost a month after I got the player.
