Input:
I purchased these Sony Headphones to use with an MP3 player on daily walks. The "in ear" type of design looked ideal for hot weather use - leaving the ear uncovered and cooler. However, because of the very light almost elastic construction I found the "seal" between the headphone and my ear felt loose and the sound quality suffered to some  degree. Obviously, this is a subjective situation; others could find the fit perfect. They are certainly a comfortable headset and as light weight as you can get.
