Dont really have anything bad to say about them. A little room to grow for future use, but still an overall great fit. These feel exactly like the same as my old ones. The company posted a size chart, I would suggest measuring your foot before ordering to make sure the length is correct. It charged correctly once. It does cushion your heels from from walking on hardwood surfaces but if you suffer from any foot or back injuries these are not great for the long term. - for a newer generation of headphones I can’t tell much of a difference in sound quality over my 2015 Bose. Took a body measurement to the feet. Works great, looks great! The rubberized layer on the mouse had worn off.
