A first observation, we see a quality headset that looks solid while being quite light and "design". The headphones are very comfortable to wear, they cover the ears well for a very good sound insulation (I was surprised because my previous helmet was bcp more "open"). So, no need to turn up the volume too (better not to esgourdes ^^) even if I have not worn in an external environment too noisy ... Its level is very well balanced, both clear and end with bass that do not crush everything (addicts very heavy bass might be a little disappointed). In short, a very reasonable price (I more have benefited from a good promotional, thank you ^^ SONY) with quality appointments.
