They do not stay in your ears unless you're sitting still. The friggen power keeps getting pressed every time a mosquito flies by which is very frustrating when you have no audio on your phone/speaker because the headphones in your backpack are turned on.

Do NOT buy these if the sound cutting out bothers you. These were a HUGE disappointment. I have many ANKER products that I love. So when I wanted some headphones to run in I bought these. The sound and fit are both terrific but they couldn’t hold a signal. Please note: I paired and re-paired them many times per factory instructions and it did not help. I also tried my indoor headphones in the same conditions (i.e. same music, same source, etc.) and the indoor ones did not have the same issue. Perhaps I got a lemon...

I can't use it. Does not fit my ear, too big. Keeping falling.

I purchased these headphones as a Christmas gift for my daughter. They arrived almost a week later then they were scheduled to arrive. They look to be built solid and to last. Now the bad; there is no audio from the left headphone. I'm looking to purchase a better set.Edit:After being contacted by Anker's customer service department, they are replacing the headphones. The CS are outstanding. An updated review will follow.

These didn’t work out of the box. They were charged but didn’t work.

Really good headphones but only lasted a month. Getting a refund.

A had great hopes for these earbuds after receiving the, unfortunately they only lasted a little over a month before the right side started cutting out. I only used these for the gym but sound quality was good for the price and they stayed in my ears. Very disappointed to see they failed so quickly.January 2017 Update ***************Anker has offered to replace my earbuds. I will update when I have more info on how these work. Thanks Anker!----2/27/17 Update: The left ear bud has stopped working since being replaced.

Only used mine for about a month and they don't turn on anymore. When I charge them the blue light comes on automatically as If there fully charged. But when I try and and turn them on they don't.

Was very disappointed to plug in these earbuds to charge all day, then, to have these die before the end of my workday. My friend bought the SoundBuds Curve and says they last him 10 hours.

worked for 1 week - 3 workouts
