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

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 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 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.

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.

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.

I think these headphones give you a pretty accurate sound, so there is no hype in them. You seem to get the straight studio sound to a large degree. You don't get boomy basses or sparkling highs.

Inimaginável a qualidade sonora. Você ouve as músicas que ouviu durante a vida inteira e as redescobre através deste fone. 5 estrelas!

Comfortable to wear, though I can see some people finding them too tight. I didn’t think it handled the mids as well as my AKG K240 MKII’s but with more use the mids are well represented. They do pickup a bit more sounds because of the frequency range. I would look to buy them when they’re on sale though as regular price is a bit steep.
