I never had back problems even at my chubby stages in life so the arch support is great. I have just received these wonderful, superb headphones the MH40 and cannot find enough superlatives to describe them! Instead of using a standard straight jack like almost every other headphone, this uses and L-shaped jack which has such little clearance that every time the jack spins around or moves, it catches onto the case and pops off. Overall, Id give it a 9/10! I bought them for training and running. Keeps my controllers fully charged and Ive noticed that it charges them pretty quick. Fits really well, & looks like they will last a long time. If it had rubber pads on even one of the vertical ends to help it stand safely,that would be cool. Deep bass, clear separation, and not tinny. From start to finish, overall this was an easy project, that this 43 year old female was able to accomplish on her own.
