    I just brought this two weeks ago. This stuff is so sick!! I went to swimming yesterday with this and man I was swimming for a long time with my favorite songs! I am in love with H2O audio! I recommend you also buy the pro kit with different ear sizes. This is awesome! I'm taking this with me to college this fall and I am going to exercise and swim everyday with a smile on my face!

    This is something every swimmer or Triathlete needs. In fact anyone who works out in a pool should have this. It completely protects my Ipod shuffle without any worries in my head. Sound is amazing underwater. It really helps me get through the mindless amounts of laps. Find the right earbud size and your good to go. Took me a few tries to get it right. Also finding the right type of goggles to fit the Interval 4g for the optimal comfort is something else I recommend. Best $100 i've ever spent. (Posted on 30/03/2012)

  3. Amazingly cool! Review by Hind Hobeika

    I've always had waterproof MP3 players, but never used them for more than 5 times because the earphones fell off, the design wasn't friendly, and it was just too cumbersome to take care of this one + ipod+ iphone.
    H2O Audio has the perfect solution: the casing protects my ipod shuffle 100% from the water, and the earphones stick to the ear and never fall off!

    I am very happy with my gear and CANNOT imagine myself swimming without it! (Posted on 14/03/2012)

    I LOVE the H2O Audio Interval system because when I am Running Biking or Swimming, I am able to train harder by listening to this music! It is so impressive to me that I am able to listen to music and know that none of my sweat or water coming off my body will ruin my ipod! THANK YOU H2O Audio for creating this super helpful ipod protector!!! (Posted on 06/03/2012)

    OMG I LOVE this thing! Sound quality is amazing and the headphones double as earplugs, so I no longer have to use drops to get the water out of my ears after a long swim. I've never had good luck with earbuds staying in my ears, and these are no different, but I just put my swim cap over my ears and they don't budge. Makes long swims SO much better. I constantly get comments at the pool about this case and I reccommend it to everyone! (Posted on 28/02/2012)
