Unfortunately, the cable crunched in movement of the latch and of the connected cable already after 1 month and after 2 months shouted an earphone at full volume, with the mobile equalizers nothing could be done.
Therefore: This headset can in my opinion with headphones like Sennheiser CX 300 II Precise Bass (this I had) keep up when they are not even a little more comfortable to wear. The speakerphone and the user option to the cable then give the added value, by which the price is really reasonable.
However, one must be aware of the risk that the cable is not very robust and relatively quickly can tarnish the really good listening experience.
