Not quite as effective when the answer isn't as obvious.
Anyways, I was wondering since I saw a vid where someone compared the K550 to the Q701 and said they were quite similar sounding with the upper hand to the K550. Since the K545 sound similiar to the K550 but bassier and more rolled off with a smaller soundstage I was just wondering how close they'd sound compared to the Q701. I've only heard the Q701 once in a store and didn't get a chance to A/B them and the K545 when they were there together sadly.
Hahaha, K545 is not on par with K/Q701 in any way except bass thump. K701 hardly delivers any if you care about that while K545 can. Then balance-wise, K/Q701 is slightly recessed in the bass and treble, giving it a very mid-forward character. If K/Q701 is not properly amped, K545 can sound as good or even make it sound like an overpriced joke of a [former] flagship, as always happens with all of these more inefficient headphones.
If K545 is supposed to be comparable to K550 as I read somewhere in this thread (or was that else where around the forums? I can't remember anymore), and another guy tells me that K551 is around on par with SR325, then K550 is definitely not in K/Q701's league.
