HD 650 Open‑Back Hi-Res Audiophile Headphones, Reference Grade Sound, Airy Design, Plush Ear Pads, Rich Bass, Detachable Cables, Lighweight, Comfort-Fit for Gaming, 2Y Warranty, Black

Its unlikely that I can add anything to this that hasn't already been said by earlier reviewers. Its as good as they say it is! I have an Audio Technica ATHm50X. I thought that was good and then i got HD650. I feared it would not be much of an upgrade! But it turned out to be a stellar upgrade. I also thought my phone with my mobile DAC (ibasso DC03 Pro) would be able to easily drive it. It can, but i have to amp up the volume to 85 ! The headphone is not for portable use. Its meant for listening at home. I use it for my nightly dose of music at my bedside. I've hooked it to an old Onkyo AV receiver. Yes, i had an old Onkyo AV receiver lying unused and made it my headphone AMP . Its too much and I know it. Better than spending another 20k on a good headphone amp i guess. The only downside is too many wires. USB-C to mobile DAC to Aux to AV receiver and the headphones. I manage because i'm on the bed and not going anywhere or doing anything but closing my eyes and enjoying pure sound. How does it sound? Well, i'm relistening all the music i have ever listened to. They all sound as if they've been remastered and new instruments added .. makes you go 'eh', what is that sound? i never noticed it before!. Is it worth this much over a noise canceling headphone etc.,? well, if you can spend on a device just for listening at home, this is worth investing. Go for a BT ANC headset if you need an all in one device.

Excellent pair of headphones. Just that you would need an amp to use with phone. With a laptop, driveability is not an issue.

This is one of the best headphones, but don't buy it if you don't know what this is for. 1. This is an open-back headphone. Meaning that, this headphone doesn't have Noise cancellation (active or passive). You can hear everything that's happening around you (you can even hear the fan or AC sounds) and everyone can hear what song you are playing. You need a quite place to perfectly enjoy this headphone. But what you get is awesome soundstage, crystal clear vocals and exact reproduction of the studio recording. 2. You don't get wireless/Bluetooth (because we know that wireless tech is not yet at par with the bitrate that a simple cable can transfer, in fact, Wireless is too far behind). And you get a very long, very wide and very heavy cable with this headphone. But don't take this the wrong way, the cable is strong and quite sturdy. 3. You don't get mic to use for calls. This headphone is not meant for that. 4. You can't use this directly with your mobile/PC/laptop (3.5mm jack or even the usb-to-3.5mm adapter). You can surely attach it, but without a proper AMP/DAC, the sound volume will be so feeble, low and lifeless that you would regret buying this 'expensive' headphone. You need something like a iFi AMP/DAC stack, or a Schiit Magni/Modi stack or something similar (I am suggesting budget options, of course you can opt for more expensive setup). This headphone NEEDS an AMP, and believe me when I say this, you need some powerful AMP to drive this headphone (meaning, utilize to it's full potential). 5. This headphone is not portable (of course you can take this anywhere, but that's not what I mean). You need a setup (desktop/laptop with a AMP/DAC setup, good Hi-Resolution files or Hi-Res streaming service like Apple lossless or Tidal and a quite place to enjoy this). This is not a headphone you take on the bus/train/flight/playground/to sleep/class etc. So, final words, if you don't know what the words "Studio monitors/Reference Class" on this headphone mean then it's not for you. Studio professionals/music producers/good youtubers will appreciate this headphone. And I am none, but I am enjoying this headphone so much that I wouldn't want to go back to anything else. I use this with an AudioQuest Dragonfly Red and the sound is simply out of this world.

I own numerous headphones collected over multiple years - Audio Technica M50, Koss Porta Pro, Senheiser HD 599 SE, Skullcandy Crusher EVO, SONY WH 1000XM4, Marshall Major III, Bose soundsport, Apple earphones and many more but this headphone (HD 650) Rules them all. Purpose - I mostly listen to Bollywood music and sometimes english music. I have noticed that the sennheiser sound signature are pretty good for bollywood/Indian music. Sound Quality - After I have started listening from this headphone, sound quality from all the other headphones feels quite inferior. This is a true upgrade for any enthusiast who is interested in listening to quality music. Instrument separation is real - You can feel and enjoy all the musical notes and male/female voices clearly. Some headphones have over bass boost that comes at a cost of suppressing music but this one is not bass heavy. The bass is deep and is very enjoyable on right kind of bass heavy music but it doesn't have overpowering bass on regular music. You can pair with mobile/laptop but for best effect pair it with an Amp/Dac. People who buy this headphone should be ready to spend extra money on other amp/dac devices to improve the listening experience. For convience - I have paird this will Bluetooth dongle Astell&Kern XB10 which has inbuilt AMP/DAC to make it easy to operate as this headphone comes with very long and heavy wires that are cumbersome to connect to mobile/laptop. Overall a worthwhile upgrade at this price point. Additional Note - For people looking for quality music at home, don't spend too much money on high end ANC (active noise cancellation) headphones but pair high end wired headphones like this with bluetooth dongle receivers.

Using this with my Fiio M9 and sometimes my mobile phone. This headphone has the right amount of treble among the high end headphones that I have heard. Lots of detail in midrange. Full sounding with adequate bass. This is another area well done. In other high end headphones and bookshelf speakers the male vocals lack upper bass and sound thin. HD650 sounds most natural and male vocals sound perfect. These are the best headphones if one is looking for natural timbre and mainly using for listening to music. By my ears these are most correct sounding - neither analytical nor too warm with ok soundstage and imaging. The phones are sensitive enough even being 300 ohms. My entry level Samsung M21 mobile drives it to extremely loud levels which I never need to reach. With the Fiio M9 the sound is more articulate. One real con is there - the headband is plastic. This is the part that flexes and will break one day. And whoever designed the glossy plastic look with the large logo honestly should look for a different profession - design is not his/her strong area. Overall great buy at < 23k. Could have come with a short 3.5mm cable for 1k more. Finding it difficult to acquire that cable now.

I honestly wanted to get a pair of the HD650s since a very long time but due to their availability issues and high price I could not but then I saw them selling for approx INR 22000, I literally jumped at them, lol. I am no headphone reviewer or even an audiophile, I do podcasting & some casual voiceovers and for those applications I think these are prob one of the best headphones you can get, they are reference for a reason, the neutrality is good, some mids definitely but they are not overpowering or unpleasant, the bass is controlled, the highs are unoffencive, these are just so good for the price! A word of caution however, that these are open back headphones so if you are consuming or creating content in a noisy environment these might not be your best bet, for general consumption if u are someone who likes an open back design and relatively flat sounding headphones, this is the pair to go for, for critical listening in a non noisy environment, go ahead no problems, however if u want a closed isolated sound for monitoring or mixing, look at closed back headphones as they offer better isolation. One more thing about the 650s is that these are 300 ohm impedance headphones so your phone or tablet or computer might not be able yo provide sufficient power yo drive these and u might experience low output at even full volumes, so make sure you have a nice audio interface or a DAC AMP which can provide enough juice to drive these. The design on the HD650s is really good, the pads are comfortable, the cushioning on the headband is enough for most people, they look good, they sound even better! So if you really have a suitable application for these headphones, don’t think much, just go for them! A bug thumbs up to Sennheiser! And Double thumbs up to the HD650s!!

I have owned HD598 in the past, had used a chifi iem cca c12, and currently use the Samsung galaxy buds pro and the Galaxy Buds 2 pro, But let me tell you this one here is something else entirely. I have never heard clarity like this ever. Pure joy. It got delivered at 2 and I’m writing this at 4pm.. and will likely keep using it for a few more hours before I take them off. Running them on a 2022 MacBook Air m2 at about 70% volume. It works perfectly. I was so apprehensive about the purchase thinking my Buds 2 pro are so good already and convenient. God this was so so so worth it.

The pair of headphones that I received are defective and sound worse than a Rs.1000 pair of headphones. I had first tried the 650's in the US at Guitar Center and was instantly in love with them and decided to purchase them, So i thought I'll order them here. But once i received them and had the time to listen to them I was shocked cause they sounded the exact opposite of what I'd heard. The sound stage of the headphones is so bad that they literally sound like they're in mono. Not just that the overall sound of them are so muddy that the cheaper Sennheiser hd560s sound way better. Also when I reach out to Amazon cause of their new policy of return they're not willing to help me. also when asked Sennheiser about the same they're like you can claim warrenty on them. claim warrenty on a new pair of defected headphones. had the worst experience ever on Amazon and now I'm stuck with a pair of defected headphones not knowing what to do with them

En primer lugar aclaro que soy entusiasta de la música y trato de disfrutarla con la mayor calidad posible pero no me considero audiófilo, por lo que mi comentario es muy simple. He estado utilizando los sennheiser hd 599 SE y es la referencia que tengo. La diferencia es bastante notable al actualizar a los HD 650, desde que me los puse y escuche algunos de los disco de referencia que utilizo se nota la mejora del sonido en general, agudos y medios bien definidos y graves controlados. hice pruebas conectados a un DAC CAMBRIDGE AUDIO modelo DAC MAGICPLUS, 24 bits 192 kHz, con trasmisión de TIDAL y archivos propios en HI-RES. Próximamente haré pruebas con un DAC- amplificador dedicado de mayor resolución.

These are the first step. Like anyone looking to make this kind of investment for headphones I did a lot of reading before buying. That is only going to get you so far. You need to hear these. Ten years ago I listened to a pair of HD600 straight off a disc-man with NO amp. I was completely blown away, I set out to find the perfect headphones for one hundred dollars, that was a mistake. I kept buying headphones in that range over the years and nothing came close. I was torn between these and the 600's, but decided that I loved the look of these and a few reviews pushed me to get the 650's. I highly suggest going to Guitar Center or some place that you can compare them, I believe the 600's maybe the superior sounding ones (it's always the ugly ones). It's been said that a good set up is the Lehmann Audio Black Cube Linear amp/HD600 using a 650 headphone cable. But there is no way I'm paying that kind of money for an amp... I'm not an expert and I don't plan to collect anymore headphones (unless I end up with a pile of extra money). If you are just getting into quality sound, these will destroy what you thought was possible for home listening. Even without burn-in, and an expensive amp and listening to a 128kbps file in itunes, you will want to throw out your old headphones, you will look at them with disgust and you will start ripping everything you own at lossless. These only get better with everything you bring to them, they are hungry for better. More than likely I'll be getting a Schiit amp as my first amp. Currently running these from an Apogee One for digtial or a Technics SA-5170 for vinyl and happy with this setup. I'd love to understand why people think these should have a dedicated amp. Things that you will notice when you listen. The sound stage will be expanded, the clarity and richness will be improved, the separation: you will hear things you never noticed (one voice will clearly become 3 layered voices, one piano will become 4, fingers will slide on strings) everything will become a personal concert. If you are on the fence about these don't hesitate, it's like going from and old TV to a HUGE HD one with bluray. If you are an audio pro, you probably already own these. If you didn't like something about these and you think they need to be amped, you have more money than brains (or very good hearing). If you want to significantly improve your daily enjoyment of music, buy these now. Like everyone else says there are cons: The band is tight, they are open so you can hear everything in the room (ie keyboard clicks and talking) and people can hear the headphones. These are most likely for home use only. Good thing they look more comfortable than most of the furniture in my house. You should know by now what you are getting into with these. These come in a huge foam lined box, there was nothing to cut, no way to tell if it had ever been opened or not. The cord is kevlar (think bulletproof vests) and replaceable, one time I sucked them into the vacuum roller (not this pair), seemed bad but survived (HD 495). They are light and comfortable to wear for me (not as comfy as my HD 428). They look amazing, much better than the HD600's. I think there is a lot that could be improved about how they are built (comfort and usability), but I'm insane when it comes to small details. You will want a multi-disc player or good quality digital music (big hard drive). What I listened to so far: NIN, Tool, The Cinematic Orchestra, Sam Prekop, Zoe Keating, Underworld, Aphex Twin, Miles Davis, Amadeus Soundtrack, Kodo, Led Zeppelin, Billy McLaughlin, Doomtree, Yo-Yo Ma, Alice in Chains (unplugged), Rodrigo Y Gabriela, Nirvana and Jimi. And I'll go to bed after I listen to everything that exists... These shine with live and acoustic tracks. Don't wait 10 years like I did. Get them now and start hearing your music for the first time. So worth it. On a side note, I'd consider getting a second pair of these rather than spending the money for a nice surround sound system. I figure the audio is as good but much cheaper. If Schiit is reading consider making an amp for movie buffs and their girlfriends to share. Update: I'd suggest the wireless HDR 120 for TV and Movies. Update: I recently found the Monolith Liquid Platinum amp for a great price as an open box almost half price from their own site. I also found XLR cables to swap for the headphones and for my CD player to the amp. I am extremely happy with this upgrade and was skeptical that it would make any difference but I am glad I invested. No regrets. A friend had recommended the Monolith Liquid Spark (probably a good option if you aren’t changing out the cables or have a lower budget), but once I found the deal on the Platinum I was determined to get that as my end game amp. I admit I should have made the investment sooner but it took me a few years too save up the money. Don’t waste these headphones maximize their potential with an amp.

Despite the numerous negative reviews for this seller, I still went ahead and ordered a pair of HD650 headphones for 200 euros. I have some issues with UPS for not providing the mailbox code upon the package’s arrival, so I had to request it from customer support. Just in case, I filmed myself unboxing the headphones, but in the end, it wasn’t necessary since the headphones arrived in perfect condition and with new ear pads. The box said “refurbished,” which is what I expected given the price. I’ve been using them for almost a month, and there are no issues with how they perform. There are some nuances about the model itself that are worth considering when buying. I work in mixing and production, and overall I liked these headphones, but I still think the HD600 would have suited me better because of their clearer high frequencies. That said, the HD650 is also a good option for music production. I tried adjusting the EQ on these headphones, and they started to sound a bit more accurate, but the difference isn't very significant. The clamping force on these headphones is quite strong, and at first it’s hard to wear them for more than two hours, but over time the fit becomes more comfortable. Overall, the HD650s have a “warm” sound and soft yet clear high frequencies. If you enjoy listening to music, you’ll surely like them - it’s no wonder they’re called audiophile headphones.

Struttura solida, leggera molto comoda da indossare per svariate ore, materiali plastici che non vogliono essere di particolare pregio ma comunque molto affidabili e che hanno dimostrato di poter resistere a svarati anni di utilizzo intenso. La riproduzione resta concentrata sulla perfetta riproduzione delle frequenze medie ed alte, i bassi risultano tuttavia adeguati e soprattutto articolati ma senza occultare la scena sonora. _______________ » COSTRUZIONE Nessuna parte metallica se non l'anima dell'archetto che permette la regolazione, il resto dei materiali è costituito da plastica di ottima fattura trattata e verniciata in maniera gradevole. Probabilmente il trattamento superficiale rischia di essere delicato ma una minima cura nell'uso dovrebbe garantire durabilità negli anni. I padiglioni morbidi e vellutati risultano molto comodi e solidamente applicati. Molto semplice la rimozione e l' installazione, operazione che ci si troverà a considerare almeno una volta l'anno data la facilità con la quale i padiglioni si consumano andando a variare leggermente la magnifica firma sonora. Buona la regolazione dell'archetto che si adatta perfettamente, risulta inizialmente molto serrato ma sono sufficienti poche ore perchè si lasci andare andando quasi a "scomparire". » PRESTAZIONI L'impedenza, come per le HD600 e HD660S2, è di 300 ohm, di conseguenza per godere appieno delle prestazioni della cuffia è bene utilizzare un buon amplificatore cuffie, possibilmente dotato di uscite bilanciate. Le frequenze medie ed alte sono riprodotte in maniera perfetta e non risultano mai affaticanti neppure dopo svariate ore di ascolto. Frequenze basse sono precisione, presenti ma non eccessive per garantire un ascolto piacevole ma fedele e non colorato diversamente da come previsto dall'autore. La scena sonora è discretamente ampia e dettagliata, l'ascolto resta tuttavia intimo come per le HD660S2 cosa che non è necessariamente un difetto, garantisce infatti una buona rappresentazione dell'immagine sonora, ogni strumento e voce sono perfettamente individuabili nello spazio dall'ascoltatore. » CONCLUSIONI Ottimo dispositivo, solido concreto e resistente. Concentrato sulla riproduzione sonora della fascia medio alta delle frequenze con assoluta fedeltà, ma che allo stesso tempo non priva l'ascoltatore del divertimento derivante da una gestione colorata delle frequenze basse riprodotte in maniera articolata ma non enfatizzata. Sono garantite ore di ascolto soddisfacenti ed appaganti senza alcun tipo di affaticamento.

Very happy with these, excellent detail and smooth bass well suited for writing progressive/techno. The bass could be a touch deeper right on the lower frequencies, it can be corrected using sonar works, or you can just get used to them and adjust accordingly as the bass is still detailed. I used sonarworks for a while but in the end chose to go without and my mixes are still translating really well.
