Tested only in stores, but canceled the idea of ??buying them. Not a good feeling in the fit, sits half dissolved and the pillows flat form factor allows external audio easily becomes disruptive, ie nothing to wear in city life. Do not like the sound was no treat, either, since they completely lack bass, and has, moreover, a very flat sound. Have not tried the wire, but it's for bt to obtain this kind. Was disappointed when they have gotten good reviews.
