I bought two of these headsets knowing that they were not going to be the best but at least sufficient for occasional use. Since I was currently using some other cheapy headset I didn't use these until 5 months after I bought them, when the old one broke. The first Coby headset lasted only 4 days. I was surprised. After four days only one side had sound. I tried the second pair that I bought and it has been working for a few months with occasional use. If you need something that will last or above average sound quality, then buy something else, these are not that great for every day use. No comment on the microphone.
