I have a $30 set of over-hear bluetooth headphones I use for running. I'd describe the sound quality as "reasonably good" and the battery life as "excellent".
For sure, I mean I always knew I could find something else looking around, but I was into the idea of having something that connected super easily and that I could trust would work. Plus half of my co-workers had them and swore by them, word of mouth is a powerful thing.
