I liked the design - looked rugged, durable, and sturdy. I know other companies provide custom sound levels, but this one is very user-friendly, able to modify each ear cuff volume separately, and has a sound test that will automatically create a new sound profile just for your hearing. They are sturdy but not heavy. Think with hard rubber bushings, age, grit, vibrations, it eventually caused paint to peel, degrade. It was one of the best gift Ive ever got because the Box had Melissa on it which is her name and the shoes also had Melissa on it it made it the perfect gift I have narrow feel and slippers are usually so wide and floppy, not these! On Smule Sing! I tell you what. hace flitback con facilidad , si la usas de referencia en fin es un robo oara el precio que tienen , lohre tener dos y jamas se conectaro entre ellas tenian un delay de 1 segundo una de otra , bose fracasate en este intento recojanla y devuelvan el dinero While I never get to wear them, I now dont have to hear about how my bad my mothers feet hurt on a weekly basis.
