Ordered two at the same time. One had decent sound quality, the other was totally different, more "tinny", no low tones at all. Then, on the one that didn't have awful sound, the ear bud broke off within a few weeks. Even before that, it would not stay in my ears while running, no matter which of the 3 bud sizes I tried. It doesn't fall out all the way-- it just slides far enough so it sounds like the sound is coming through a door from the other room. Could not return because we didn't use them for a few weeks after getting them. Junk, save your money.

These have very good sound, but the hard plastic, coiling retainer is annoying on the back of the neck. The retainer creaks when you turn your head from side to side. The controls for on/off, volume, track and phone use are not touch-friendly, and they're difficult even to see. I found that the hard plastic retainer interfered with the temples of my eyeglasses. So, the sound is fine, but the rest (an interesting idea) doesn't work very well. I returned it on that account.

After reading the product description and a handful of reviews, this product seemed like a real high-quality set of headphones, right?Wrong.At first glance they looked cheesy. After touching them, they felt worse. After reading the instructions, which are written in poorly translated English, I seriously questioned the reviews. After charging them for the first time, the rubber USB port cover won't stay closed. After finally pairing them with my phone and trying to listen to music, I knew I had to return them.Seriously, it feels like I was sent a knock-off set rather than what I thought I was buying!DO NOT WASTE YOUR TIME OR MONEY.

These work great! The little button to control the volume and skip songs is a little confusing, and if you turn your head away from your phone while you're running the music can cut out, but they work great, I love that there isn't a long cord, and overall I'm completely satisfied

Works OK but the sound isn't that great, hard to get them positioned right and they hurt to have in your ears for any length of time. Stuck them in my travel bag for use on trips because they are compact. Bought some better ones for daily use.

Finally. Headphones with great sound. I would definitely recommend. Comes with different size ear buds. You have to find the right size buds for your ears, or the headphones won't stay on securely. Other than that, they're perfect.

I've only had these headphones for two months and they've already broken. The left plug came out of the counsel with the wires popping out. I managed to put it back in place but now there's no music coming out of the left speaker. Not a good purchase. Even before the headphones broke, the sound quality started buffering more frequent. Battery life is shorter than advertised also.

The headphones did not feel like they stayed in place when I moved my head. The sound was tinny unless I held the earpieces in place. I wanted these for listening when I was exercising and they did not seem very good for that.
