The mask that was included and is functional. I was even able to wear my glasses with them on yesterday and it was still comfortable the whole day. I also have a small phone compared to most, so you would think that even in a case, the straps would be snug without being overstretched. I do not know about the durability though; the outer soles were not thick. Such a great purchase! I ordered a small and it fits just like in the picture. I replaced the original? Technics cartridge in my SL-5 turntable with this one after reading good reviews. Sound is physical even at the microscopic level. I’m kids have AirPods. The simulated surround mode is just ok as I didnt really notice a difference in various spots around the room.
