I didn’t appreciate the way the UPS driver threw my package on my porch. I’m using them as my recording mic and backup earphones for my sennheiser momentum earbuds and except the bass there’s no difference in sound quality. 0 connect seamlessly to my iPhone X, and my iPad Pro (2018 3rd gen). I have not tried to move it around but I had to move it to the lower area of my phone for another charger. Id say if 0 was no sound at all and 10 was to the point where your ears are popping, the headset goes up to 7. Thank you, Sennheiser for your tireless research into the pursuit of perfect sound and musical excellence. Instalation was easy and all the tools needed came with it. She wore them for a long time in her room. Never thought I’d run into this problem after covid. Sooo happy I found these!
