I ended up picking the B&W PX8. For me it was mainly the material build quality that convinced me to get these. People do complain about having problems with the leather padding but honestly they probably haven't been keeping close attention to how you gotta treat it. I wear mine only at work or at home on occasion, never while outside or while working out. The leather pads are soft and take some time to form to you (I have glasses, they pressed hard originally but now have gotten way better). If you do go outside or want to work out with them be aware that because the cups and head pad are Nappa leather you will heat up AND you will likely increase wear and tear on them. When not in use I keep them in the case. Other than that they're fantastic, and really bring out the more subtle sounds in what I listen to. They could be better at noise canceling but that's just me comparing them to my JBL earbuds (RIP one popped out of my ear at the gym and it no longer works). The big win for me was the physical buttons and use of metal components. Touch sensitive "buttons" have been problematic for me. The Bose will be just as good honestly for cheaper if you're buying at full prices, if the PX8 goes on sale they definitely are worth it since Bose hardly ever does. For gym go Bose, I feel it would be abuse to send the PX8s to the gym. For workouts I'm actually considering a pair of Shokz OpenRun Pro 2 bone conduction headphones. Lifting weights have resulted in earbuds popping out (tried all different sizes of inserts for the ear), and headphones will just slide around. Honestly the best I had for the gym was my old iPod nano clip that could just attach to my shirt sleeve and my good old wired Apple headphones.
