Read the rave reviews, so I decided for this RS 180. listening Results is catastrophic !!! An absence of medium, no transparency, no depth, everything is flat even with files and audiophile quality recordings, poor dominant bass, treble also almost absent etc ... Moreover comfort is limit, ergonomics volume is poorly studied (the tiny on-off between small volume keys) Forcing it "stops" the helmet instead of "reducing the volume" Conclusion it is not a music headset but for radio, audio books it's ok but paid dearly !!! Thank you to put comments when we know, but not when you think you know! Comments are there to help the consumer, not the smoke.
