Bests & Worsts Reviews from Amazon

These headphones sound alright for the price, and the battery life is great. However, I bought them as running headphones, which these are terrible for. They do not handle sweat well at all (despite claiming they offer two layers of sweat protection). They are loud enough to about 30% volume for a bit, but at about 10 minutes into my runs, they become muffled to the point you can hear basically nothing but the vocals on full blast. They also do not stay in my ears at all, despite there being about 10 different sizes for the buds. I heard good things about these headphones and really wanted to like them, but they are just not good for running. Update: The pair I have won't even charge anymore. Only 2 months old. Updated 2: After contacting Anker, they are sending me a new pair, no questions asked. Update 3: The new pair is working much better. They are staying in my ears a lot better, and they don't seem to be getting blocked out from sweat this time. And best of all, they actually charge and work! Update 4: The new pair now doesn't turn off properly. They make the sound like they are turned off and they disconnect from my phone, but the LED light remains on. They die within a few hours, so I have to leave them permanently plugged in when not in use. I really hate these things and wish I had never bought them at this point. Updated 5: As of early June, the third pair no longer turns on. These headphones are garbage for runing, and I am guessing not actually sweat proof (like advertised).
