Product Description          Powered by H20 Audio technology making them waterproof up to a depth of 3 feet for 30 minutes, the Trax Custom Fit Sport Headphones are made to survive sweat, humidity and rain. Easy to clean, you can rinse them off for a fresh pair of earbuds before every workout. A unique moldable memory wire, five earplug options, and a cable clip give you the options to create a comfortable stay-put fit that's uniquely you. The memory wire is designed to hold shape, yet stay flexible so you can create the perfect ear hook that's comfortable even with sunglasses, or change up the fit for each activity you do.

    Exaclty what is promised.
  

*by D***Z on Reviewed in the United States 🇺🇸 on April 29, 2013*

These are great after ruining several other headphone sets with my sweat. I run about 5mi three times a week, and most weekends I also go for a 6mi trail run. Needless to say, I sweat a lot. These have worked perfectly even if they get very wet from the sweat on my hair, although I have to say I have not tested them underwater.Be aware that these may be a little uncomfortable for some people, as they are relatively invasive: they go all the way into the ear and kind of pressurize it, which feels a lot different when you're running that when you're just, say, sitting in the bus listening to music.The one thing that gives me trouble with these is the length of the cable. It is fairly short (I didn't realize this before the purchase), so if you're tall chances are you probably won't be able to extend it all the way into your shorts' pocket. This is a problem because these hold very firmly to the ears, and so you actually feel them pulling on you during your workout if the cable is over stretched. This can be very distracting when I run, so my solution was to use an armband for my mp3 player.

    Finally an earbud that holds up to sweaty workouts!
  

*by E***E on Reviewed in the United States 🇺🇸 on November 12, 2014*

I love these little earbuds.  I have been searching forever for earbuds that will stay in my ears while I run or workout and also won't completely break the bank.  I was about to resign myself to dropping some serious cash on the Bose Freestyle earbuds when I decided to take a chance on these ones.These have a bendy metallic lining near the earbud, so you can choose to make them over the ear if you'd like or you can wear them as normal earbuds.  The sound quality likely won't please the pickiest audiophiles, but they are plenty loud and sound just fine to me.The best part about these little guys is that they are completely waterproof.  If you tend to run in the rain/snow or just sweat an unholy amount when you work out (like I do), these are a lifesaver.  They stay in your ear and there is not danger of them shorting out due to sweat.  I even accidentally sent mine on a trip through the washing machine and they still work fine!Should be noted that there is no microphone/track switching/volume adjustment dongle on these, so if that is a must-have for you then these may not work out the best.Overall, wonderful earbud for any price, but especially for what you pay!

    Cable is too short, plug is slightly to small
  

*by A***R on Reviewed in the United States 🇺🇸 on September 8, 2015*

The cable is slightly too short, which causes the audio jack to pull out slightly if you keep the audio device in your pocket or a waist strap when you run.  This probably causes the "poor audio" (No Bass) problem one reviewer mentioned (since the bass end of the audio is the first to go as the jack gets pulled slightly out of place).  It also probably causes the "won't stay in" problem another reviewer mentioned (although I found this problem went away entirely when I switched to slightly larger ear buds -- they provide multiple sizes).  I am going to get an armband to see if that solves the "too short" problem.  If not I will be sending them back.-- UPDATE -- So, the arm thing didn't help.  The problem is that the jack is just a little to small, and it won't stay put in the jack on my phone (yes, other jacks work fine).  I suspect this is a manufacturing quality issue -- I'll bet they work great if you get one of the ones that is milled correctly.  I will be sending mine back.
