Two days ago I got my friends hd 650's and 600 ...
I observed too much hd600-650 comments in the last pages, and I wanted to understand what went wrong for these people.
Jesus, how ? I mean, really, how could anybody even compare them with X2 ?
Conjested, tiny, dull, no soundstage whatsoever, very hard to drive, depended on hardware too much...
I tested them with mica origen, fx audio dac x6, fiio e10k, SB X7, my alc1150 onboard, Ipad Pro, and modi multi+magni combo...
I played with EQ settings, used APO, tested them with many many diffrent situtation. Spotify Premium, Apple Music, flacs, movies, games ...
How can anyone bear hd650 or hd600 after trying Fidelio X2 ?
First thing was the soundstage, hd600 had non, hd650 had some but nothing compare to the X2. Hell, even Dt770 had better soundstage in genaral.
I thought it will be other wise. Beacuse I know that, treble and air means information-soundstage. I experienced it with my AD900X-1000x.
But compared to the Senns, with 50mm and angled drivers, X2's were much more successful in the soundstage area. Games, movies were much more engaging and uncomperably better with X2.
Imaging is also better on X2 side.
600 and 650 have their treble area, a bit more information compare to X2 but nothing special there. With hd600 I had some fatigue even.
And the BASS ??? OMG. X2' like god, 600 and 650 are worshippers. The hit, punch, oomph, quality, quantity wise X2 destroyed them.
Resulotion was on par with each.
Only and only good side of hd600/650 was Mids... Especially on female vocals, they shine. "Gortoz A Ran" from Greta Bradman gave me goosebumps with hd650. X2's are bit recessed in mids on female vocals. Male vocals still on par, in my opinion.
But thats it guys. Only some female vocals with good mastering/recordings.
On the other hand, X2's were more coherent, with punchier bass, less fatiguing, much more bigger soundstage, with much more 3D or 360 sound, much more enveloping sound, layered.
I had them 48 hours. Listened and tested in very diffrent conditions and gears.
I apologize for this statement, but who says "hd600/650s are better than X2" should have their ears checked.
I think hd600/650 are showing their ages. Sennheiser must refresh them.
