This is not what I ordered and this is not what is advertised! I dont know if it does much for my pituitary system, but it does relax me. The sound disappeared on one side. The only actual negative feedback that I would have for this is likely on my end: if I listen closely with the headphones plugged into the mic, I hear a little bit of fuzz. Swapped them around and they went on with ease. The sound quality is very good, both in music reproduction, and in calls; and the other parties on the call report good quality from the microphone. Very happy with my new wireless charger. The app has ads but its meh. Not sure if I can send them back. I Also realised that when you put it on it feels very uncomfortable.
