I really like my Bose Soundsport Headphones. The battery lasts about 6 hours which is great since we now live in a world where headphones are needed for work, school, and exercise. I also love that I no longer deal with headphone tangles, which seemed to be a constant problem. The sound quality is great and I appreciate the fact that I can tune out the chaos around me...sometimes they are are a little too good at cancelling out the noise around me. I wish they came with more replacement parts ear pieces. I seem to loose them frequently, but I think that's a personal problem, rather than an everyone issue.
