    Amazing headphones for the price
  

*by D***E on Reviewed in the United States on March 4, 2014*

I purchased this for working out and running since my other headphones were low quality and the backup pair would not stay in my ear during vigorous runs.  I bought the red ones, and wasn't expecting much outside of somewhat decent sound quality and pretty looks for something that I would just use during my workouts.Boy, was I wrong. These headphones are great. The sound quality matches headphones that are 3 times the cost as these.  For instance, I prefer these over Beats (Which are over-priced) and they have the same "sporty" look to them.  I can run in them at full speed without worrying about them falling out of my ear or becoming loose.  I can lift without them falling out.They don't have sound-isolation technology but at about half volume and up, I can't hear a damn thing. Which could be bad for some runners, but keep it below half and you'll be aware of your surroundings.Clarity of sound is great, and the bass is great on my trance and rap.  After about a month, these things have been holding up very well and I am a very heavy sweater.  Would most definitely recommend this brand.I got the red and black ones, and they're very stylish, but would look at getting the  white ones next time if and when I need to get another pair.

    Best pair of sport headphones I've owned
  

*by G***. on Reviewed in the United States on April 13, 2014*

I broke the plug on the first pair I bought.  Awaiting delivery on the 2nd pair. The broken plug was totally my fault, so I'm not holding it against the manufacturer. As for performance, two issues. Depending on whether you wear glasses and the type of frames you may have some comfort issues. 2nd issue involves finding the right size ear pieces. It's a lot of trial and error for me. After I found what I thought was the right size, I had to go one size larger to get the most comfortable fit. Took about 3 or 4 runs to get it. Sound quality was OK and build quality was excellent. I did a half marathon run last month in 3 inches of rain. Even in monsoon weather the headphones performed well, they did not slip off my ear or shorted out. I broke my plug when I slammed my car door shut on it on my way to the gym.  I was pissed but quickly ordered a replacement pair.

    Im not disappointed with the purchase
  

*by N***E on Reviewed in the United States on March 29, 2015*

Im not disappointed with the purchase. I bought them to run, and they do stay on snug.. They take a bit of getting used to tho.. and putting them on right and finding a comfortable position takes a few minutes. They tend to hurt a bit if not put on right. Just rotate a bit until comfortable. But once on, they stay on.. Sound is ok. Nothing extraordinary.
