Acceptable, but nothing more. The wires are extremely fine, and in a very soft plastic, which protects only very little the wire inside. The type of cable that could blow up if one draws directly on it to disconnect, unlike any other proper quality cable which can be drawn like a patient without causing any damage. So I have to take, not on the cable but on the connector to disconnect the point that the air almost trivial but actually makes a big difference in its daily use. Works great if no one touches it, but I do not give much of his skin if I had to reconnect and disconnect regularly.
