professionalheadphonesUltrasonePRO 900 & Edition 8Ultrasone Pro 900STROTHER BULLINS thinksthat the PRO 900 could wellbe the cause of some fightsin the future, they’re just sodarned desirable.S-LOGIC PLUSThe basic Ultrasone S-Logic systemdoesn't, as the name might suggest,use any digital magic – the systemis purely physical. The fundamentalmechanic is a 'de-centralised'driver positioning that, accordingto Ultrasone, means signals arereflected off the surface of the outerear before entering the ear canal– a process more akin to listeningon monitors than headphones.The 'Plus' in S-Logic Plus addsnew "precision dampening withmicro-acoustic reinforcement",which optimises the relationshipbetween driver, buffer-board,and spatial parameters. LastlyS-Logic Plus incorporatesre-designed, finely-tuned earcups.That should be enough techtalkto make even the most hardypragmatist drool. Admitting youdon't know what buffer-board is,is the first step to recovery.THE REVIEWERSTROTHER BULLINS is Editor ofPro <strong>Audio</strong> Review.Perched atop Ultrasone’s high-quality professionalheadphone line, the new PRO 900 closed-backheadphone is a luxurious, comfortable, andwell-made pair of studio-grade cans.Specifications include a 6Hz to 42kHzfrequency range, 40mm Mylar/titaniumdriver, 40Ω impedance, 96dB maximumSPL, and a weight of 0.65lbs.The complete PRO 900 packageincludes a canvas-covered hardshellcase with coiled and straight 10-footcables terminated with Neutrikconnectors, a quarter-inch to minijackadapter, spare ear cup pads, a20-song reference audio CD compiledand largely recorded under thedirection of Ultrasone, and a manual.Featuring proprietary S-Logic Plustechnology – which in part requiresoff-centre drivers angled towardsthe listener’s outer ear – the PRO 900has a unique sound for headphonesthat you may, or may not, be used to.However, it is my belief that the S-Logictechnology greatly contributes to thePRO 900’s impeccable imaging andfine detail necessary for engineers whouse (or would like to use) phones formeticulous editing and monitoring.Comparing DetailIn direct comparison with highqualityconventional studio monitors,I did hear detail in the PRO 900’sperformance that wasn’t apparent inthe monitors; for example, in listeningto The Beatles’ I’ve Just Seen A Face, Idistinctly heard a harmony vocal,albeit short and mixed way back,with depth and detail that Ihad never even noticed before(and I’ve surely listened to thesong several hundred timeson dozens of sound sources).To my ears, the PRO 900 offerspronounced detail and acousticpresence at comparativelylow levels; this quality willsurely have you monitoringat lower-than-normal SPL, thushealthier listening habits over time –“I distinctly hearda harmony vocal…with depth anddetail that I hadnever even noticedbefore…”a notable and beneficial feature indeed.On the PRO 900, pristinely produced vocal-orientedpop music – with reference material rangingfrom music by Beyonce to Big & Rich –was translated with notable ‘air’, wellexposed reverb tails, and an overall‘depth of mix’.At The TopThe PRO 900’s street price is atthe top of our industry’s pro- orstudio-specific headphone range.As such, you’ll initially cringewhen handing them to a musicianin your studio (or at least I did).Luckily, the PRO 900 is a headphonebuilt to take common studio abuse,such as ear-bleed-inducing trackingsessions while perched on the heads ofrock drummers, guitarists, and vocalists.The PRO 900 is also physically fit: ready forstudio wear and tear and, dare I say, builtto be droppable. I’ve yet to use any set of‘phones that I consider worth buying forstudio use that can’t be dropped, yanked,or accidentally kicked across the flooragain and again. In use as musician cans,the PRO 900 will seal well around mostears and heads; thus, you can give themplenty of juice and not suffer much frommonitor bleed into your microphones.In my time with the PRO 900, everymusician that used it had nothing butgood things to say about its sound andfeel, nearly to the point of disappointmentif I didn’t hand them the sole pair ofPRO 900 cans I had during multi-musiciantracking sessions.In summation, I wholeheartedlyrecommend the PRO 900 to modernrecordists and mixers who need atop quality set of pro headphones,and whose work generally rangesanywhere from dynamic classical,jazz, and lightweight pop toconservatively compressed rockmusic. The PRO 900 is an incrediblemusician’s studio headphone, too.Just be prepared for a band fightif you’re a tracking engineer with onlyone pair. ∫50AUDIO MEDIA JULY 2009
Edition 8 headphones are serious pieces of workmanship and material excellence. The ear cups have a classy rutheniumprecious metal coating, which gives them a mirrored finish. The headband and pads are covered in dark grey Ethiopiansheepskin leather – very soft and exceptionally comfortable. They have a new titanium plated tri-bass-tube driver,contributing to a frequency response quoted at 6Hz to 42kHz (yes… 6Hz), and they incorporate the Ultrasone S-LogicPlus technology (see the PRO 900 review opposite for more). Even the supplied storage bag is made from fine Madrasgoatskin, produced in France. No, I didn’t just describe the latest in designer handbag opulence – I just described apair of headphones.To test the Edition 8s I sat down with several pairs of headphones and ploughed through some favourite recordings,including some raw DSD material.The first thing to note is that the Edition 8s did sound the best. Not very descriptive, I grant you, but when it comes to,say, identifying particular strengths like bass reproduction, imaging, transient response, and so on, I got a little tied up.The fact is that the Edition 8s won on every aspect.If you want the gory detail, I found a complete and stable centre, and convincing LR soundfield in some stereo classicalrecordings that I would never normally trust to headphones. In fact, this particular focus brought it home to me exactly whynobody should trust ‘other’ headphones in a critical stereo set-up. It was also these examples that proved it is possible topick out instruments in an orchestral recording – if the recording is good enough. The less easily pin-pointed symptom ofthis was a correlated connection between the left and right channels that formed a whole image – not two speakers stuckin two ears.A couple of good vocal tracks and a drum recording to die for also cleared up a few other points. First, the LF is as clean, aspresent, and as fast as can be. That is, the bass wash you normally get with less able headphones went away – replaced by themicrophones that recorded the takes. To explain,one vocal hung out its dirty washing with somelow-down plosives from a close-miked mouth thatjust didn’t get through on the other headphones.This and a tight kick drum on another track wasenough to show that Edition 8s succeed where somany others fail – they allow you to experiencewhat it really sounds like to be the microphone.That’s something that is normally only possible witha great studio monitor.Tracking and auditioning stereo materialon headphones is usually fraught with risk.Sometimes they can tell you everything is great,until you get back to base and the monitors tellyou that you might need to have another go.I feel bound to say that I would trust the UltrasoneEdition 8s to both expose problems when it’swrong, and give you the thumbs up whenit’s right.The question of whether anybody would payover a GB£1,000 for any pair of headphones isanother thing altogether. If you want reasonable,inexpensive headphones, then the high-endUltrasone ranges don’t fit the bill. If you wantsuperb headphones that don’t cost the earth,then the Ultrasone Pro series is ideal. If you wantsuperb headphones that have something extra,then Edition 8 is your [goatskin] bag. They arethe ultimate sound person’s special present, orindulgence, or talking point, or demonstrationof appreciation that extends beyond the purelyfunctional. ∫INFORMATION£ Pro900 – GB£323.00 (exc.VAT)£ Edition 8 – GB£1,100.00 (exc.VAT)A Ultrasone AG, Bernrieder Str.17b, D-82327Tutzing, Germany/BavariaT +49 (0) 8158 9078 0F +49 (0) 8158 9078 50W www.ultrasone.comA UK Distributor: <strong>Audio</strong> Limited, <strong>Audio</strong> House,Progress Road, High Wycombe, Bucks, HP12 4JDT +44 (0) 1494 511711F +44 (0) 1494 539600W www.ultrasoneuk.comE info@audioltd.comUltrasone Edition 8ultrasone pro 900 & e8THE REVIEWERPAUL MAC is the Editor of<strong>Audio</strong> <strong>Media</strong> magazine.AUDIO MEDIA JULY 2009 51
