Sound stage is so-so, but I think we have to be fair and not compare these cans with 5-10 times more expensive ones. The quality of the wireless mic is as good as the best wired mics Ive heard. The wear down margins are slipping, or I may be making more miles? Upper parts hold up, but soles are softer and have wear out issues. It has beets, but i hope the added sugar or flavoring wont limit its effectiveness. The slipper itself even says 7-8 size, but I definitely feel like my heel is at the very edge of the slipper because of the trim that they have running along the edge. Not ideal, but I can fill the void to make it more secure. The fit of the device in the ear was decent. I wouldn?t buy again because of how strong that was. The style is very good!
