I had a listen to these today. Don't trust the demo music in the display. It's rubbish. When I paired these to my phone the sound is very good for the price. I think very well balanced for Bluetooth headphones. Good value at this price.
I decided to buy these over the PXC 550 II (which were on-sale before today at $299 - I actually bought the HD 458 BT which are identical but red-highlights because they were $149 before today). While the PXC 550 II do have more high-end range and clarity, I found the sound of the HD 450BT (which are actually the ones I tried in-store) to be more pleasing. The PXC 550 II didn't have enough punch and the treble was a bit harsh to me. I was happy losing a little treble (these are Bluetooth right, so compressed high-end isn't really something you want to emphasise), in exchange for added (but still measured) bass. And I'm not talking muddy rubbish. I've got higher-end headphones at home and done some work recording and producing music, but I liked the tone of these, as a relaxed tone that I think will be good for commuting. I'm not going to mix recordings on these, but they sound good for what they're intended to be.
EQ worked well in the app. Increasing bass a little worked well, and only showed minor tasteful distortion in the most bass-heavy tracks like bass tests. It's a standard Bass/Mid/Treble EQ too, with full slider range, compared to the very weird EQ in the PXC 550 II (so weird I can't even remember what they called each range, and I'm not sure it was actually that simple either - weirdest I've ever seen). You lose dynamic ANC but standard ANC seemed alright as best I could test in the store. The app automatically detected that there was an available firmware update, which I think is great. Heartening to see there are updates.
They fit my large (3XL Flex Fit) head. Not sure why some people struggled with fit. Ear cover was good and comfortable.
Anyway not sure why I'm telling you how they compare to the PXC 550 II, other than to say that these are good value headphones at this price. Though if you don't mind the colour get the 458BT if you see them cheaper.
Some complained that the controls were confusing and unclear, but I found I immediately remembered which controls did what after looking at the quick start guide once. I prefer it to touch controls.
Lock-in cable is good too if you use it, rather than letting the cable get yanked out.
