I have bought many glass shields trying to find the right one, until I found supershieldz. Questo sandalo è molto comodo e,nonostante la zeppa,è leggerissimo Finally I turned to Amazon and jumped up to a size 8. - Just the right height - not too tall, not too short. I havent had any issues with them randomly un-pairing or turning off (like with some other earbuds. Cant say enough good. I have wide feet so I wasnt able to use my favorite heels at one point but I can finally walk in them so comfortably. Regarding COMFORT, I am extremely happy with the way they feel in my ears. Leider überzeugt der Kopfhörer überhaupt nicht. but Ill never know.
