HTC One with Sennheiser PXC-450 Noise Cancelling
Looking for some advice.
I own these over these ear noise cancelling phones. Spec'd at 450 ohms active mode / 150 ohms in passive.
Since I will get 99% of my use on airplanes, they'll be in active (noise cancelling) mode unless I run out of batteries.
Given this information, would I be better off using the internal sound card on the HTC One and getting the massive grunt of the E-12...
Or, will the E-18 supply plenty of gain and control and be superior in SQ becasue of its DAC?
I've read that the HTC One sound card is pretty good (mind you, this only in comparison to other cell phones).
Perhaps the high 450 impedance of these phones is non-issue because this is only when they are in active mode and their iternal electronics are engaged (just guessing).
Right now, with phones plugged straight into cell phone, they lack warmth, bottom end lacks heft, and volume is always near max. on both cell and headphones. (Despite reviews I've read that these headphones were a bit bass heavy).
All praise ta dose wit da knowledge.
