Otherwise, very cute and sporty slides that make me feel like a college student again (not that we necessarily want to relive those days). Lempeigne a une doublure intérieure en genre de vinyle. Dont know its my sons Dont get me wrong, these Sennheiser earbuds can pump out the bass as much as you want without distortion. Clear crisp sound. Okay, yes. I had to move the receiver onto the USB-hub 2ft away from my head. I have a bone deformity in my foot that is not fixable with surgery. Connectivity is much better, it doesnt drop out. I like that it sleeps when idle to save the battery charge.
