I use this headset every day on the train and I'm very happy. I'm not a sound engineer so I can not give precise technical assessment, but the quality is perfect for me. The sound insulation is very good. It must certainly be better, but not at this price and bluetooth. Son (only?) Default, is its lack of stability. He, at my tendency to fall forward.
