    This is my third one over the years, usually the left earpiece goes out then the right, I hope design improvements have been made.

    I babied this device with TLC, to no avail. The wires are so small, they have no ability to be substantial enough to last more than a couple of months.  Wasted this money and the purchase of the 4th generation shuffle to go with it, when I already had a shuffle.  Left ear wire broke with in 2months.  The right went out yesterday.  Needs to be beefier.

    I had a really hard time getting it open so I could turn on my IPod Shuffle - then as a used it , it would not close so I had to order a new case.  New case came in and the music would not play from the Shuffle.  Customer service was "over the top" in replacing it for me.  What a great company!!!

    I did prime the case as instructed, but then I have been Unable to open it once my shuffle was placed inside. We have contacted the manufacturer and they have been unable to help. I probably will have to crack it open to get my iPod out. Do not buy!!!

    Sound quality is good. Ear buds keep water out of ears and they fit snugly. Don't fall out. (I'm using a swim cap also.)
    Having a little difficulty figuring out the most efficient way of getting it into position and operating, but that should become easier with more uses.

    Performs as advertised. Has improved my workout. A little complicated to get in place, but not so much as to complain.


X-1 Audio

X-1 Audio, previously known as H20 Audio, features a line of rugged casings for MP3 players, which allows for the use of expensive and delicate digital music players during water sports activities. Partnering directly with leading MP3 manufactures, X-1 Audio has created a line of sturdy and practical casings, patented waterproof headphones, and underwater accessories. Established by athletes for athletes, X-1 Audio is made up of a team of avid swimmers, surfers, wake-boarders, sky-boarders, and kayakers.

X-1 Audio began in 2001 as a graduate project at San Diego State University that aimed to bring music to Scuba divers. It just didn’t seem fair that runners and other terrestrial athletes could train with the benefit of music, while swimmers, surfers, divers, and other aquatic athletes were bound to silence. The company's beginnings pre-dated the widespread popularity of the iPod® and other MP3 players, so the first dive case was designed to house a portable CD player.

After many prototypes and adjustments, the first production model case was made for the iRiver MP3 player in 2002. It came equipped with the power-amplified diving headphones similar to those that are integrated into the current, state-of-the-art "iDive Underwater Apple iPhone/iPod MP3 Housing." More recently, X-1 Audio incorporated in-ear technology into the "Surge" and "Surge Sportwrap" headphones.

In 2005, the company designed the first waterproof cases for iPod. For the first time, swimmers and surfers could take their music into the water. As the iPod evolved so did X-1 Audio, which led to the innovation of the "Interval Waterproof Headphone System," which fits both the 3rd and 4th generation iPod Shuffle™. In a constant effort to improve sound quality and comfort, X-1 Audio also introduced the "iPod Shuffle Swimbelt" and the "Amphibx Armbands," which come in three sizes to accommodate many sizes of MP3 players.

X-1 Audio product design and development is based on years of prototypes and close collaboration with top athletes like Olympic swimmer Natalie Coughlin and triathletes Greg and Laura Bennett, and surfer Laird Hamilton.

Today, X-1 Audio's corporate headquarters are just feet from the ocean (in other words, testing grounds) in Pacific Beach, California. The company is committed to developing the best high-performance waterproof and sweat-proof sport headphones, armbands, and other accessories on the market. X-1 Audio doesn't want to be limited to producing a cheap, featureless player simply because it's waterproof. The company strives instead to create something that functions well in any conditions, providing high-quality sound, easy control of the audio device, and access to music no matter the conditions.
