          Great battery and comfortable

          I used these for running and they were so comfortable, they stayed in place. I haven't had them for very long so I feel I can't rate the battery life yet. So far I think they're great!

          Work well so far

          I own a pair of power wireless beats 3 and I bought this pair because of the awesome price for my kiddo. These are so comparable in sound to my beats. The price just can't be be at. The battery life is impressive. My husband tried them and he wants a pair. The case is nice good zipper and nice storage spot for charging cord. The headphones arrived quickly, I love the color combination. Charged up quickly and they are more comfortable than my beats 3.

          Great quality for the money!!!

          I really like these headphones so far. Charging is simple and easy, and they are comfortable to wear. My only minor complaint is that the volume/power switch on the cord is heavier than most and tends to pull the earbuds lopsided and will pull the left earbuds out from time to time. Other than that, sound quality is good for the price and they connect easily via Bluetooth.

          Excellent Customer Service, decent Product!

          The sound quality is amazing. However, the only thing I would say is that the bass is pretty much nonexistent unless you push the earbuds all the way inside your ear canal. You’ll basically be sacrificing comfort for some bass. Since I use these for the gym often, bass would definitely help me lift the last couple of reps of my set.

          Okay for my purposes

          I have always had trouble with ear buds, specifically the just don't fit well into my ears. These wrap around the outer ear and then sit on top of my ear opening. For this reason I don't get the full sound that is probably available. The rubber tips seem to come in a few sizes but even the smallest ones don't fit into my ear canal. This is a problem for me, others may have better luck with the fit.
