These are great and very well priced. First of all I did not slip going down a dusty dirt road! They are comfortable and solid. Will keep for my son but he?ll half to walk mindfully so the dont fly off ??. Unfortunately, the battery life is NOT as advertised. Truly though my only complaint about it is that when you press the buttons on the headset the clicking sound is very loud in my ear. Sound is clear and crisp. Highs are decent but considering Ill be running or breathing heavily while working out, they tend to get drowned out anyways. VERDICT: The Bose are the most comfortable, the Senns have the most elegant volume/pause/skip control, and the Sonys are by far most fun as a fashion accessory. I like these, but I wish the sizing was more clear since it?s unisex.
