There isnt any sound quality loss when using this with my M50x which is just what I was expect from a Sennheiser products quality. When I had my partner and daughter try it, both overwhelmingly preffered Sunny Health for the same reasons. I have a pair in black, ordered a pair in white. The carrying case makes it easy to transport everything. One so far under size and this one a defect from the start. It just feels that there is all high and low and the sound is unbalanced as a result. As a 9, they don?t even slide up and down on my heel. I removed the closet doors in my room to push part of my bed into it to free up some space, but I still needed somewhere to put my clothes so I bought this rack. This yoke is much sturdier than the less expensive models I had way back. The hull is a fairly complex shape with the sides being almost square and continuing underneath into a pontoon section on both sides and a fairly flat bottom in the middle.
