Consumer Audio HD 650 - Audiophile Hi-Res Open Back Dynamic Headphone, Titan

These are hands-down incredible headphones for non-bass heavy genres. They have a way of letting you hear things in music that you've just never heard before, and might just make you cry. It's truly an experience, and I adore them for it. They're comfortable (though a bit tight-fitting at first), well-made, the cord is good and long. They feel solid but they're not too heavy. The one downside is they do have a significant bass roll-off, meaning they don't perform as well for genres like rap. Everything sounds fine; they're just a bit too 'polite' for music that's meant to have a lot of punch or heavy bass, so if you're looking for that, look elsewhere. But for most other music; rock, pop, classical, some electronic, the experience is -phenomenal-. If you've never experienced a good pair of Senns, you're in for a treat. You will need a DAC/headphone amp to power them, as they are high-impedance headphones. I went with the Topping DX3 Pro+, which works just fine, though I had to use the high gain setting to get the full power out of these. Also, although they sound great out of the box, a little EQ will really let these shine - in Windows, Peace on top of EqualizerAPO will let you choose some great AutoEQ settings that you can then tune to your liking.

These are a part of “knights of the round table” headphones. Let me get something straight — there is no one perfect pair of headphones. It’s a curse to the wallet but yet it’s a blessing in the sense that headphones are a magical journey of taking two of your senses (hearing and touch) to whole new levels you may never experience by simply just by being in it. With so many headphones out there, there’s that many ways to explore audio and more! Exciting, right? I am an audiophile and have a room dedicated to my headphones as well as listening. Audio is an incredible passion of mine and I want to share my take on these 650s! 1: So, Sennheiser is among the crem-de-la-crem (pardon the spelling) of headphone producers. 2: Sennheiser is a great brand to get into headphones when you’re new to it. It’s also got great value for performance. You honestly can’t go wrong with them. 3: If you’re on a budget and can really only afford to just have that one or two pairs of headphones. The Sennheiser 650’s are a jack of all trades with its sound profile. They are a definite buy for sure! Paired with a Khadas Tone Board and JDS Labs Atom, you can have a pretty top tier, affordable setup. For real sides! 4: These work well with so many different types of DACS and amps. I personally pair them with THX789’s from Mass/Drop, Khadas Tone Board, or my Okto Research 8’s. The THX 788 made by Monoprice is a nice combo DAC/AMP. 5. In terms of the Sennheiser line, there’s the boss tier (not necessary at all to own) like 800 and 820s. There’s the studio recording line denoted by PRO. There’s the lower end with the 598 and below. The 600 range (where these headphones sit at) is the sweet spot of excellence. If you want a bass-y emphasized performance, go with the 58X from Drop.com. They’re the resurrected Jubilees which are an updated, updated version of the HD580s. These are super solid, great for listening for long periods. You can’t go wrong. You can plug these into a device without an amp and get great volume. If you want super duper separated sound with ridiculous detail with more revealing performance in the highs and mid/highs, the 600s are your go to headphones! They’re very objective (an audiophile term generally meaning “as-is” or “unemphasized” as possible). With the wrong setup, they can sometimes even be a little sibilant. The 650s are truly the Goldilocks of the HD600 line. These emphasize the mids much more than the others. It’s often considered a sin by some audiophiles to use EQ functionality to adjust the sound. I can say that the 650s are at that point where they can be lightly EQ-ed to offer more bass and treble response. Now, onto the last thing that I think is important to mention — these have been replaced and succeeded by the Sennheiser 660s. They’re a worthy successor to replace the 650s. They are pretty close in frequency response. However, the upgrade comes with the comfort (clamp force) and the consistency of the drivers to produce frequencies. What does that translate to? - The HD660s really do a good job of sounding good with vocals, slightly less warm, and sound good without a lot of readjustment on your ears. They’re on the brighter side than the HD650. The brightness is a personal preference kind of thing. For some, they might like this for classical music. For some, they may find themselves hitting user fatigue sooner than the 650. My opinion: The HD650 are still my go despite the update with the 660s. I think that the 660s is wonderful but I prefer to stick the HD650s because of their versatility. I can listen to them for hours! It’s a great starting spot for audiophile tier headphones that will always, always be my daily headphones for all kinds of music. They’re also a great starting spot as well as a great spot to end on. Additionally, I would check out the Sundara by Hifiman if you’re wanting to explore planars. They’re very much like the 650s of planar headphones. Enjoy and happy listening! :)

If you're willing to invest in a good DAC and AMP combo to pair with these headphones, then they are highly worth it. I have mine paired with a Schiit Audio Bifrost 2/64 (DAC) and a Schiit Audio Midgard (AMP) with Mogami Gold Balanced cables between the DAC and AMP. Sounds great with acoustic/folk/rock/classical/orchestral/vocal/country music also performs well with most pop music. I would not recommend these for RAP. The clarity is great, but you'll probably find them a bit lacking in bass for Rap music.

I recently purchased a new pair of Sennheiser headphones to replace my old ones, which I had been using for several years and was always very happy with. I’m pleased to see that, unlike many other brands, Sennheiser has managed to maintain the same high level of quality despite all the changes in the market. The first thing I noticed was the signature Sennheiser sound: detailed and clear highs, balanced mids, and a tight, controlled bass. The audio quality is still impressive listening to music or working with these headphones is truly a pleasure! The build quality is also top-notch: everything feels solid, with no cheap plastic or loose parts. I really hope Sennheiser will continue to maintain these high standards and not go down the same path as other brands whose quality dropped significantly after changes in ownership. For now, I can only recommend these headphones they remain a benchmark in the headphone world!

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.

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.

Editado el 21 de junio de 2023: Llevo siete años con estos auriculares (desde 2016) y siguen siendo mis favoritos. He probado otros auriculares más caros (HIFIMAN Edition XS, Sennheiser HD 660S2) pero no hay otros que tengan este timbre tan realista, la neutralidad que ofrecen y la respuesta de agudos tan refinada. Lo único que puedo aconsejar para mejorarlos un poquito más es amplificar con ecualizador los subgraves (por debajo de 100 Hz). Estos auriculares son una maravilla que vale cada euro y que te pueden durar más de diez años sólo cambiando las almohadillas. ----- Editado el 25 de septiembre de 2020: Han pasado cuatro años y medio desde que los compré , y todavía los disfruto muchísimo. Hoy los he estado comparando con unos Fidelio X2HR de Philips y he podido comprobar cómo estos Sennheiser tienen los agudos más refinados que he escuchado en unos auriculares. La única pega que he tenido con los HD 600 es que he tenido que cambiar las almohadillas este año, y son bastante caras... Aun así éstas aguantan hasta 3 años de uso exhaustivo. He añadido la imagen de una medición de la respuesta de frecuencias en el rango de los agudos, comparándola con otros modelos como los Philips X2HR y los Beyerdynamic DT 880. Esta es una de las razones por las que me gustan tanto los HD 600. La respuesta de los agudos se siente de buena calidad, suave y detallada, porque no sufre ningún pico irregular, al contrario de tantos otros modelos. ----- Después de haber usando los Beyerdynamic DT880 durante tres años, hace un mes decidí probar estos auriculares, ya que había leído que eran sinónimo de neutralidad. Me arrepiento de no haber comprado estos tres años atrás. Me han encantado desde el primer momento. La comodidad es excelente (los DT880 son también muy cómodos, pero prefiero estos por ser completamente abiertos). El sonido es tan detallado como en los Beyerdynamic pero, además, puedo disfrutar de una respuesta de frecuencias neutra. Estoy de acuerdo en que algunas producciones pueden parecer planas, "aburridas", pero desde mi punto de vista eso es problema de la producción y no de los auriculares. Además, siempre se puede remediar con un ajuste de ecualización. Estos auriculares ganan presencia en los medios comparado con los DT 880 y no me cabe duda en que el sonido es en su conjunto más natural. No producen nada de fatiga auditiva. El único público al que no recomendaría estos auriculares es a quienes buscan sólamente bajos explosivos de pistas electrónicas. No estoy diciendo que estos auriculares tengan mala respuesta de bajos, de hecho me parece correcta, pero de ningún modo llegan a ofrecer sub-bajos "aniquilantes". En esta opinión intento ser objetivo, pero tened en cuenta que en el mundo del sonido toman también mucha importancia los gustos, y si bien yo disfruto los HD 600 por encima de los Beyerdynamic DT 880 y los considero una mejor opción, a otra persona le puede parecer lo contrario. Pero no cabe duda de que los Sennheiser ofrecen una respuesta más neutra. Y, desde el punto de vista objetivo, neutralidad y fidelidad son sinónimos. Añado que en realidad no son tan llamativos como parece en la fotografía, sino que son más discretos y elegantes. El color azul es muy suave, casi gris. Esto para mí ha sido una agradable sorpresa (esto lo escribí hace años, ahora el diseño es gris oscuro...).

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.

ゼンハイザーの撒き餌ヘッドホン？であるHD599SE購入からまんまと釣られてグレードアップとしてこちらの商品を購入しました。 私はオーディオマニアではありませんが、HD599SEで開放型ヘッドホンの装着感の軽さ、長時間つけてても蒸れない気楽さにハマりました。 HD599SEはとても気に入っていたのですが、１年ほど使用していてもう少し音質の良いものが欲しくなりこちらのHD600にたどり着きました。 以下、HD599SEとHD600を聞き比べてみた個人的な感想です。 【HD599SE】 比較してみて初めて感じたのは、HD599SEは半開放型とでも言いましょうか、ヘッドホンとは耳元でギュッと密閉された空間で音が鳴るものである。というイメージから離れすぎない鳴り方に感じました。 ですので、開放型で気楽な装着感でありつつ耳元に音が近く、多少音楽に迫力も欲しい。そういうヘッドホンが好きな方はHD599SEのほうが好みかもしれません。 しかしHD600と聞き比べると構造的には開放型なのかもしれませんが、音的な解放感はいまひとつです。 【HD600】 比べてHD600は、まさしく開放型ヘッドホンです。という鳴り方です。 イヤホンで音楽を聴くと頭の中で音が聞こえるような印象を感じることがありますが、あの感覚に近いですね。そしてその上で音がこもる感じがなくスッキリと広がっていくというか。 うまく言えないのですが音がずっと耳の近くに居続けない感じですね。耳元で鳴るスピーカーのような。 HD599SEよりは音場も広いと思いますが、用語に詳しくないので上記は音場が広いというのとはまた別の感覚かもしれません。 音質は、まずシンプルにHD599SEよりもきめ細かく感じました。 鳴っているそれぞれの楽器の音を聴き分けができるくらい音のひとつひとつの解像感も高いのですが、その上でヴォーカルが埋もれない綺麗な聞こえ方をします。変に前に出てくる楽器がない感じです。 ですので、何か誇張をしたり劇的に音が変わるのではなく、それぞれがそれぞれとしてちゃんと聞こえるという印象です。 それゆえに人によってはあっさりした音だと感じるかもしれません。 まとめると、HD599SEと同様に長時間使用しても疲れが少なく、HD599SEよりもう少し音のきめ細かさや解像感のある音質と、音としての広がり、解放感を求めていた私にはイメージ通りで追加で買い足して後悔のない商品でした。 なお、こちらのHD600はよく据え置きアンプ必須のようなレビューを見かけますが上記は１万円程度のドングルDACで聞き比べした印象です。ヘッドホンの本領を発揮できてるのかはわかりませんが、スマホ直挿しでも一応それなりに鳴りますのでご安心ください。 HD599SEをお持ちで、HD600が気になっている方の参考になれば。
