Works well with my HyperX . Now, I REALLY wish that I had called Amazon in a timely manner, and requested a refund, or at the very least, a grievance of some form. The sound quality was great and the super human hearing feature was put to good use! Cons:-theres no way to dock the earbuds. They do, however, change the sound signature of your earphones. These speakers are awesome! Das Einsatzgebiet ist deutlich größer. Unfortunately they do not have 1/2 sizes, so I guess Ill be wearing socks with them. Vom Sound bin ich auf jeden Fall sehr positiv überrascht. Once I received my second order; So far I can honestly this little gadget works great!
