The sound of the handset is surprisingly good. Comes close to the quality of larger (on-ear) headphones in the price range of 40 EUR. The build quality is fine. Have the earphones already many times ordered receive (for me as well as friends) and always the same good performance. Very pleasant is the interesting form of earphones. I often still hear the evening on lying music side. The individual design of the pressure compared to other's in-ear headphones very well balanced and long endure.
