good sound quality at any point of view, medium and treble are clear and the bass well prononcées.les materials are good bills without top niveau.Mais beings that price, it's really a good product.A flat anyway the same with the microphone means his own breath in the background and a slight sizzle, but really nothing alarmant.au level connections, everything is clear and well explained, the wire length is quite sufficient. Very good report quality prix.enjoy !!
