I bought this back in April, but have hardly gotten to use it, and I don't think these are going to last me very long. I've used them sporadically since end of May. At the beginning, they worked great even though it skipped a few times, but the last few times I've used it since July, I can hardly understand anything anymore half the time. That's how bad it is now. This is really disappointing as I have grown to love the Anker products since last year when I bought my first product from them. I have been a loyal customer and really feel bad that I have to give this such a bad review.

The battery died after a month of daily use. It stayed in my ears through intense workouts, but dead earbuds and useless.

sent it back

DO NOT BUY!Update: Anker sent me two additional pairs. This was written in Dec 2017, by mid June 2018 neither work. These just do not have a long enough life span. They are clearly not sport headphones.I have bought two pairs of these in the last 18-24 months and one lasted about a year and this one last 6 weeks before just not working. First the light goes out and stops indicating blue/red etc, then eventually it just stops working all together.If you reach out for a refund or to return they ask for hard to find details from the charging cord or separates and keeps up with universal charging cords.

Were not comfortable to have around neck and the the quality of phone calls was terrible , I return it immediately.

When I got these I was quite impressed, they had great sound and for comfortably. I bought them in may and they quit working in September, sound only comes from one side now

Broke in 1 month

These head phones are terrible. I have only had them 2 months and they already stopped working. They don’t keep a charge if I could I would send them back but it’s past the return time. I would not recommend these they are a waist of money

Initial problem was the battery is awful, it wouldn't hold a charge more than a few hours. After three months the headphones started shorting out and wouldn't hold a connection to my phone. Now they are completely dead.

Poor sound quality, poor ear fit, and poor blue tooth connectivity. These are a shining example of what happens you try to go cheap on headphones.
