I bought 2 orders of this product to give as gifts to my childs volleyball team. RGB on a wireless mouse4. Botones configurables para lo que quieras. on time. Also, I lost the ear tip like a month after getting them and the other sizes dont fit as well. I bought uv beads and put them in with my stuff. Dont expect concert quality audio playback. My daughter has small feet and is 16 months old. Usually they loosen after wear, but this one is made out of a different material and i dont know if it will loosen and it is so tight that it actually cuts into the top of my foot. This headset has a feature permanently enabled called Sidetone, which basically picks up all ambient sounds around you, as well as your own voice.
