Quality: superb comfort it encompasses both the ear and do not be crushed for sure! I wear glasses and with great! sound never cuts any concern with even very good reception through 2 wall!
inconveniant: micro receptive enough (my APPLICABLE) I have not even placed on a 2 cm of my mouth to speak or people will not hear me! and the stem too short micro bass are not huge either but good enough for a sublime sound quality!
