I guess I am asking if the MM450 is basically exactly the same sound quality as the PXC 310 when used with the cable (or if the MM550 is the same sound quality as the PX 360 when cabled). I would assume they have the same drivers and accoustic properties...
I short no does not sound like the others - its a lot better! Main point being the tuned units + tuned amplification [+ tuned BT transceiver]. No internal amp in a consumer device will ever come near that of course - klonky HiFi stuff we nerds love here exuded as they hardly are movable and permit headphones of a totally different caliber.
Long answer is of course if you deactivate everything including the battery powered build in amplifier then yes they might be close but just the enclosure difference and tuning will make it off some - never really tried thought as I never had a PXC 310 to compare with at the same time doing exactly that since its rather pointless.
The hole point for using these is that you have some device without a build in amplification device since your on the move or you would use something better for that like HD5xx or something at least. I'm sure if you used a battery powered amp + high-end IEM [+ dedicated BT device] you can come near these or beat them depending on tastes but again that hardly counts as the external amp will be a lot of price+weight in the equation.
Also the internal amp is awesome hence why the battery is exchangeable. I have no idea what the batteries costs but we have 2-4 laying around charged or charging so we never run dry between destinations.
