The bass is not perfect, but it is acceptable for a non-demanding. Like most products of this type, the cables are fragile at the entrance in the atrium, we must be careful not chewed. The integrated volume control is functional, but somewhat difficult to use if you have large fingers. It also seems quite fragile. Small foams provided for headsets are too thin and thus wear out quickly; their replacement is expected soon. The housing and the cable winding mechanism operated without trouble. This product is still quite cheap, so I was not expecting a perfect product (even on the part of Sony).
