Really like these. The sound-stage is a mixed bag, not as wide as the HiFiMan 400s but enough to get some idea of placement of instruments. A very well made case. I really wanted to like them but they had constant issues. I returned ans purchased a Large and it it very snug, the way a waist trainer should be. It comes with few sized of cones that make you able to find fit for your ear. Perfect size and style for my guest bedroom. The rubber sole is uper thick, so the cold doesnt get through and I wear them both with and without socks and they are snug and comfi. Holds the phone securely. Realizing this, I finally figured out why I couldnt hear footsteps very well in the game Counter Strike Global Offensive, which encourages me to buy another pair of the M20x for my desktop, as well as a mic.
