Wow what a nice opinion and review buddyR70x, no question.
The comparison to the 650 is probably a more similar one, as the 650's have a touch more low end than the 600's. However, I have never liked Senn cans. I have owned 599's which I found possibly the most dull and 'meh' headphones I have ever listened to, well, at least at a high-ish price point. Some people rave about them, but for me they were so bland and unimpressive. I have also had 280 Pro's, and while they isolate very well, again, I found the sound signature so sterile. I'm not necessarily talking from an 'accuracy' point of view here as some of my most beloved cans are fairly 'neutral'. But, the 'three blob' closed in stage, and overall tonality was so unappealing to me.
Many people say that the R70x has a very narrow soundstage....I could not disagree more. While they are not as wide as DT 880'S, Fidelio X2's and K712's, they are still perfectly wide and hit the perfect sweet spot for me. Narrow enough to be intimate, and not too wide as to be artificial.The R70x also has some of the best imaging I have ever heard in a headphone. Possibly the DT 1990's are the only ones to eclipse it in that regard.
Then we come on to tonality and timbre. In my opinion, no headphone I have ever tried does this better than R70x's. I am a studio engineer and the tonality of this can is just so precious and precise. Every note and instrument sounds how it should, with no colouration or distortion. Listening to music, I have never had another set of cans that give me so much soul, and emotion from my tunes. Their tone and timbre is unmatched, yes, even by the 600's and 650's.
Funnily enough, the only area of the 600/650's that I could say is superior to the R70x's, is the upper region. Not that the highs are bad on the R70x by any means, it is just slightly more resolving and crisp on the 600/650.
So, that tells you everything you need to know. The R70x is an absolute bargain of a headphone and is without a doubt, the best headphone in it's price range. Eclipsing even headphones I have heard approaching or surpassing £1000. Price point often has no bearing on quality with headphones, and I would much rather have 3 or 4 pairs of these than 1 pair of HD800's.
To me, they are the perfect headphone with the most exquisite soul and tone I have ever heard.
I found this R70X mid freq is very good for vocals and acoustic instrument. But a lil bit eq on treble is good for me
Got mine (Taiwan made) trade for Japan made. And I can confirm there are no difference between them from sound and build quality. Just different label under the head swing (Japan or Taiwan)
I just love Japan made lol
