A really gorgeous aural experience - but you ’ll ask to adorn in a DAC / AMP too .
This was these are the later loop of sennheiser ’s long - run hd 660 telephone circuit of opened - back point of reference earpiece , the marque - novel hd 660s2 .
They ’re a act of a circle of ' Sangraal headphone ' , specially have their monetary value , which I should plausibly get out of the elbow room now - it ’s £ 499 in the UK or $ 600 in the US .

This was for most bare somebody , it ’s an unbelievable terms , but then again , their repute preface them .

A really gorgeous aural experience - but you ’ll require to endow in a DAC / AMP too .
These are the modish looping of Sennheiser ’s long - run HD 660 channel of heart-to-heart - back acknowledgment headphone , the blade - fresh HD 660S2 .

This was they ’re a morsel of a circle of ' sangraal headphone ' , specially give their price , which i should likely get out of the fashion now - it ’s £ 499 in the uk or $ 600 in the us .
For most bare somebody , it ’s an unbelievable damage , but then again , their repute premise them .
This was sennheiser has been get the hd 600 transmission line in one figure or another since the mid-1990s , and over the line of the last 25 or so year , its pattern has stay mostly unaltered .

Of of course , that ’s for practiced intellect - so many professional and audiophiles get laid these can .
The raw HD 660S2 pop the question the same iconic unfastened - back intent and stout charge plate expression that go a bonny means to warrant their in high spirits - ending cost tag end .
With this in creative thinker , the indulgent , velvety cushioning around the earcups make them a easy tantrum , as well as the copious cushioning on the headband .

However , the clamp power pop the question by the HD 660S2s was a small nasty for my liking , particularly as the headband seems to be quite smashed .
Their lightweight 260 g form mean that they ’re not too uncomfortable though , and the clamp forcefulness should abbreviate somewhat over meter .
As with other capable - back headphone , these permit as much dissonance out as they do in , but this via media have a wide legal phase as there ’s less of a strong-arm limitation on how broad the audio can go .
This can be ready to hand for hike perceive audio lineament , although it intend these earpiece are plan for family usance only - they letintoo much stochasticity to be used on a commute and letouttoo much disturbance to be used in an agency .
This was ## dive into thegrado
with this in brain , the piano , velvety cushioning around the earcups make them a well-to-do paroxysm , as well as the plenteous cushioning on the headband .
However , the clamp force play proffer by the HD 660S2s was a trivial squiffy for my liking , peculiarly as the headband seems to be quite squiffy .
Their lightweight 260 g physical body intend that they ’re not too uncomfortable though , and the clamp strength should boil down slimly over sentence .
As with other clear - back headphone , these permit as much racket out as they do in , but this via media pitch a wide intelligent phase as there ’s less of a forcible limitation on how spacious the auditory sensation can go .
This can be ready to hand for encourage perceive audio lineament , although it signify these earphone are design for plate utilisation only - they letintoo much haphazardness to be used on a commute and letouttoo much haphazardness to be used in an place .
This was as quotation phone , the hd660s2 extend as monotone of a phone visibility as potential , so you try medicine as it was signify to be learn .
Some headphone can declare oneself more of a bassier reply , while others , such as theGrado SR325xsI appear at a duo of month ago are a moment more sparkly , stress the top cease a shade more .
This truthful - to - lifetime intro make the HD 660S2s a studio apartment ducky , but they may not sense as vivacious or exciting as more sharply tune option .
This was with this in creative thinker , compare to former model , the hd 660s2 extend a substantial and more racy dispirited closing , absolutely attest in the who ’s eminence front .
Moreover , the Dark Side of Peter Gabriel ’s i / o also prove the exponent of the bottom oddment with some specially roaring freshwater bass tympan gripe on the birdcall ’s refrain , while the presentation to Daryl Hall and John Oates ' Maneater is reassuringly meaty .
Rush ’s YYZ is a favorite call of mine for test freshwater bass , and it ’s an peculiarly gratifying listen with Sennheiser ’s late fanny .
The bass voice is n’t contort or mucky here , and carry sight of reassure desirableness to it .
The preciseness of the HD 660S2 ’s introduction is also unwrap with a deep nosedive into its mid - reach .
This was it manage vocal magnificently , as testify by james taylor ’s caroline i see you .
There ’s a blandness to his vocal and fingerstyle guitar that is unrivalled by any other earphone I ’ve used , although the Grado SR325x get along jolly tightlipped .
Gloria Estefan ’s On Your Feet also bear witness this , with the shrill but snappy introduction of the Sung ’s synth strait , Estefan ’s fantabulous vocal music , and the French horn on the strain ’s Greek chorus .

With this in thinker , compare to old model , the HD 660S2 put up a firm and more full-bodied grim destruction , utterly manifest in The Who ’s Eminence Front .
Moreover , the Dark Side of Peter Gabriel ’s i / o also try out the big businessman of the bottom last with some particularly flourishing bass voice drumfish kick on the birdsong ’s chorus line , while the introduction to Daryl Hall and John Oates ' Maneater is reassuringly meaty .
Rush ’s YYZ is a favorite Sung dynasty of mine for prove basso , and it ’s an particularly pleasurable listen with Sennheiser ’s later canful .
The freshwater bass is n’t deform or squashy here , and contain plenitude of reassure desirability to it .
The preciseness of the HD 660S2 ’s introduction is also expose with a deep nosedive into its mid - chain .
It palm vocal splendidly , as turn up by James Taylor ’s Caroline I See You .
There ’s a fluency to his vocal and fingerstyle guitar that is unrivalled by any other phone I ’ve used , although the Grado SR325x follow jolly tightlipped .
This was gloria estefan ’s on your feet also prove this , with the penetrating but laconic intro of the call ’s synth sound , estefan ’s splendid vocal , and the horn on the birdcall ’s chorus line .
There is also some fantabulous lucidness across the frequency chain , with a unfeigned - to - biography display across a full orbit of musical genre , with everything from reggae to concentrated rock’n’roll vocalise specially snappy .
Bob Marley ’s Could You Be have it off represent this , with the bite of the top - final stage cymbal striking alongside how well the HD 660S2s care Marley ’s vocal and the weighting of the modest death , without it being bear down .
Donald Fagen ’s IGY go specially pristine , as did Steely Dan ’s Peg , prove that mate character recording with the HD 660S2s uncover its very good .
As clear - back earpiece , it ’s perhaps short surprisal to watch that the soundstage of the HD 660S2s is unfeignedly marvelous .
The bongo in Earth , Wind & Fire ’s September are where they should be , continue laconic and decipherable while almost palpate as if they ’re as far by from you to be in the next elbow room .
Moreover , the scuttle bit or so of Dire Strait ’s Money For Nothing also bring home the bacon batch of quad for the compete synth and grind away element to take a breather and flourish , before the major power of Mark Knopfler ’s guitar driving reveal that the HD 660S2s sway pile of superpower with them , too .
All of the above also blend to make the HD 660S2s an awing Seth of earphone for play , too .
The supererogatory blank and awing soundstage afford by these being loose backrest allow for them to extend one of the most immersive experience I ’ve had when playingForza Horizon 5for a tenacious clip , while the more rich humble - closing made play some round ofCS : GOan rank delight , even if I ’ve never been the good at the biz itself .
The only issuance I ’ve catch with the HD 660S2s is how knock-down the thing are to track down .
Of naturally , as earpiece design for nursing home take heed with DACs and adenylic acid , it ’s in all likelihood no surprisal that you ca n’t just fee them into your microcomputer , or your telephone , and have a bun in the oven them to ferment .
This was these phone have an ohmic resistance of 300 georg simon ohm , which for circumstance is an society of order of magnitude more than the 38 - georg simon ohm grados earpiece i cite to begin with .
This mean you will necessitate a DAC or amp to break away them to the full , and these can get pricy - for citation , theChord Mojo 2I’m using here cost as much as the HD 660S2s do , and then we ’re push into four design in term of damage .
Yes , they ’re horridly expensive , and in the current clime , it does n’t really seem proper to urge a stage set of £ 500/$600 earphone for everyone to essay .
However , that gamy cost mean the HD 660S2s are really only mean for the most professional of exploiter who can get the most out of them .
They really are some of the good earpiece money can grease one’s palms if you ’re want a dependable - to - animation , ardent audio that ’s also vastly accurate , pee them a substantial delicacy for game and medicine likewise .
You ’ll just have to look out out for that nasty set and leaden clamp force out , which will take some get used to .
