It?s a shame they didn?t take their time to inspect the items before shipping them out to the customer. Ive been using it on my bed even and its standing up great so its great for face timing. Sennheiser was nice enough to RMA the unit and send me a new. I like the foam shoe bed over rubber that sweats. However my toe wouldnt fit properly through loop. They are lightweight and did not shift. I play Battlefield 5 and I have tried its audio 3d setting and I have tried the headphones with their settings and i have tried with Dolby Atmos.
