this kind of connector (phone jack) rather has a reputation for unreliable, even when it is a "compatible" device. Although it is maid in China, it is sold with the brand, and contacts are good. The sound quality is that we can expect from this kind of listener when it is deemed good. Obviously not ç'est the quality of a big helmet headset So good quality / price ratio to see in the time, because it's still fairly cables end in the atria. The part between the telephone connector and the "handsfree" to jump from song song, or answer a phone call, rather "solid": about 3mm diameter, but flexible enough!
