Im still trying to get to know all of this thats why my evaluation of the sound quality is kinda vague but if you listen to anyone who review this headphones its pretty much it straight up like badseed tech and z review said. No assembly directions included. I had these for 3-4 months, wore them exclusively for everything. But with the US focus, there’s a tendency for the stories to be a little too similar – by broadening the view to cover more of the world, I think you’d end up with an even more compelling book. Disappointing (No issues with the wrist-band and Ive used it quite a bit - same construction, just a different size band). 5" and 125 lbs and got a small. They fit prefect. my old ones are old. works well and I love blue switches and always have.
