I took it for use with a laptop mainly to adjust the volume (on the headphones it is often either not at all, or it is very unreliable). Works well-you can connect two pairs of headphones 3,5 minijack and microphone at the same time. There are off buttons (when you press off the edge, it does not always work, in this case you need to press harder) and turn off the microphone. And a very comfortable volume wheel (the only thing is that you can make it thicker so that you can turn it not only from above, but also from the side). Packed well, you can take it. Good seller, 5 stars.
