For a budget headset, the microphone and sound are good. The cups are large and completely cover large ears. Beware, they are suddenly much shorter in length than the Game Zero/One and HD 6xx series. In the Game Zero, I had 3 adjustment steps to the maximum on each side, in the HD 660 S, 5 steps to the maximum. However, these GSP 500s turned out to be unexpectedly small at the maximum: with a comparable length of the temple, it all goes into width. To just put it on, I have to move it to the middle between the top of my head and my forehead, which is very uncomfortable. From the lobe of one ear through the top of the head to the lobe of the other ear, I have 48 cm - at an approximate glance, the headphones fit up to 44 cm. There was no other choice but to give them as a gift. A woman's much smaller head was fitted comfortably.
