plantronics (good sound, poor fit, clunky looking /fugly)
Beats studio 3, poor sound, tight fit - ears will get sweaty with prolonged use. Good for winter... keeps the ears warm. Sleek looking
Bose qcii: good sound, amazing comfort - can be worn all day without a problem. Head and shoulders Obote the competition. Not as sleek looking as the studio 3’s but acceptable.
Was torn between the Sony’s and the Bose, but trying on instore, Bose was the clear winner in terms of comfort and fit. But to be fair, I have not had extensive experience with the Sony’s.
