Amazing sound for a great price
I bought these headphones thinking that I would get subpar sound but I needed earbuds to work in my motorcycle helmet as my Powerbeats headphones were just too bulky. I now use these everyday when riding and the sound is at times better than the $200 Powerbeats headphones. The battery life is great and I would recommend this to anybody. Why spend $200 when you can spend $20 and get almost the same sound quality. I'm sure there are audio files out there that could tell the difference but for someone like me and pretty much everyone else out there you're not going to be able to tell and you'll save some cash.

Left headphone stopped working
UPDATE: May 22, 2019 - Four months after buying I could not get them to pair to any of my devices. I kept persisting and eventually they paired to my devices. They were great for about a year until the left headphone died. They were amazing when they worked. I have to buy something new and I won't buy this brand again.June 2017 - AMAZING!!! These headphones have excellent sound. Deep bass. Very easy to set up. I use them on both my laptop and cellphone.

Great sound
Awesome sound!! I was really surprised how these had great bass. Only issue is there weight of the controls pull the one side it of my ear sometimes.

About 10 days after the 30 day no return date ...
About 10 days after the 30 day no return date, one end of this headset stopped working without an identifiable cause. I now have a mono ear piece. The microphone appears to be shorting out as people I call get enough static that they cannot understand me. Other than sweat, these headsets were not subjected to water.

Not worth it.
Boo!!! I’ve both three of these. Each only lasted a few weeks before malfunctioning. Waste of money.
