AMEN to THAT! I've just unboxed my Senn HD598 after biting the bullet and getting it on amazon.co.uk AND I LOVE THEM! It is my first pair. Totally correct about it being an all rounder. Particularly good on accoustic, jazz and baroque music like IL DIVO (tenor vocals), Celtic Guitar (accoustics), Alicia Keys Unplugged (female vocals), baroque (Jarrett/ Petri - Handel Sonatas), Operas ... etc but most surprisingly the bass came through strongly, beautifully in Black Eye Pea's rendition of "Where is the Love" like I've not properly heard before. Thus very pleased. Strong contender at the time was the AKG 702. The HD 598 won because (now verified fr personal experience) is was not "as" difficult to drive - I've listened to above on both my ancient minicompo as well as an unamped iPod Classic and there was little difference.
Hvg said that Jamiroquai's single 7days7nights came through rather thin.
=======================================================
This was my Amazon review...
As a newbie to the HP scene (ie being a token HF person), it was a daunting task to sieve through the plethora of hps available on market with all it's technological "advances" or "non advances". Product comparison posed a challenge as well as my country (where I am from) trails in model availability and most shops carry a limited range. Hence this purchase was a leap of faith based on review findings and forum discussions. I was really just searching for a simple but quality pair of headphones for my new clavinova whose 40Wx2 speakers did not do full justice to it's true sound capability - hence the hp... but then, it got bigger than ben hur. Keeping to a narrow focal range, it was a toss between the AKG K271MKII, K702 or this. I had needed something that had excellent SQ in all registers (but did not need doosh-doosh bass), accurate reproduction, sound separation, some spatial soundstage yet which doubles as a listening hp for my repertoire of music driven from the new (now old) i-toys (pod,phone,pad). Repertoire comprise mostly accoustics, baroque, tenors, jazz, light rock, and a little bit of everything else except heavy metal & hip hop. Thus the consideration that it should not be too difficult to drive. Priority was for unplugged/ accoustic music (piano, flute, guitar), jazz, tenors, operas, baroque classics and and some legacy audiophile music to sound amazing.
Here's the take.
The packaging & product visual was high quality ...with made in China (miC) sitting subtly at the bottom flap.
UPS topped themselves again with a record delivery time of 4days fr order date (to Australasia). The touch & feel was quality. However, tempting as it maybe, I would not want to fall asleep in them as one wouldn't want to risk turning over and stressing the headphone joints...
First sound impression (on the clavinova) driven fr the clavi was disappointing - results were varied depending on the instrument type used or accompaniment style. Though touted as not needing breaking-in, I found that the hps quickly improved within 2-4 hours.
From the following sampling on the HD598 (unamped), personal finding as follows: (to be continued)
Exquisite: Il Divo (shivers!), Amici, Michal Hromek's Celtic Guitar (bliss...), Dire Straits (Love/Gold)Harry Connick Jr, Buble, Alicia Keys (Accoustic), DECCA World of Vivaldi, Puccini's Turandot & Handel's Six Recorder Sonatas (Jarrett/Petri) & The Messiah (Trevor Pinnock)...et cetera & probably Stairway to Heaven;
V Good/Ordinary: Freddy Cole, fourplay, Michael Harrison & Friends (already sounded like on the the old hifi which I haven't yet hooked up or tried on the hp), Eagles (except Hotel California), Celine Dion, John Williams,(vocals slightly veiled)...must try Clapton unplugged, Sting, U2 & BonJovi on this as well (update later)
So-so: Jamaroquai Seven Days Seven Nights
Bad: when playing mediocre recordings.
This hp excels in making intimate quality recordings of vocal jazz & tenors, accoustics, audiophile recordings & great for HDtv shows eg UKTV The Bill (surroundsound effect eg brings to life ambient sounds within movie).
Where it falls short is where recording is not par excellence - may not be suitable to noisy rock subject to recording quality (perhaps this is where it may need amping - let's hope sound quality improves with it). The abv were testdriven unamped on my old Sony mini-compo (I guess that's cheating) - but then I was still very happy when I hooked it up to my old iPod Classic'07.
I have another miC HP coming - the closed AKG K271MKII but what I really want is to get my hands on the love-it-or-hate-it K702 or K701 (looks better) that everyone sings about or thinks severely overrated. As for now I am still getting a hang on what "coloured" "neutral" "balanced" "airy soundstage" sound like. And what amping potentially does to a pair of HP. Hv a pair of FiiOs E7/E9 coming as well to see what wonders it can do to the 598, if at all.
That said, I'd gullibly paid full price for this from amazon ...and since I have no comparison, can't verify if it's true that the HD598 is really just a modified ver of the cheaper HD558 (with pads taken out) or the HD595s which are currently very steeply discounted & a real steal. I would hv EXPECTED Sennheiser to do better than that! If so, cosmetically, I think a $90-100 premium is not worth it HOWEVER, it is a great pair of headphones & I have grown rather fond of it overnight. Be nice if AKG would send me a pair of miAustria K 702s for reference. How do these ppl get freebies?!
Meanwhile...am off to assess other music/ genres on the HD 598
