Once considered (at least by us!) "The World's Best", the Sennheiser HD650 remains one of the absolute favorite audiophile headphones. This full-size open-back reference can delivers silky smooth, accurate sound with a laid-back, mellow tonal delivery. The HD650 is a gorgeous can for acoustic music of all kinds and for listeners seeking warm, richly rendered detai without brightness or glare.

Detachable headphone cord makes for easy upgrades to Cardas or CablePro standard and/or balanced XLR cables.

This model can only ship to USA addresses due to manufacturer restrictions.

Applications:

Sennheiser Electronics in Germany has always taken its time developing its audiophile reference headphone line. In fact, they're well-known for blissfully ignoring the apparent audio industry demand to come out with "brand-new" products every single season. We think their patience and persistence researching and developing high-end headphones has paid off handsomely over the years. With the critically lauded HD650, the music is beautifully smooth and relaxed when it's supposed to be, and liquid-quick and punchy on demand -- and so effortless that you just fall worry-free into its lovely sonic embrace. It's a top-flight audio experience hearing the Sennheiser HD650 properly amplified, its warm yet refined and seamless sound coupled with good wearing comfort has kept this model in the top echelon for years as one of the best headphones on the audiophile market.

Liveried in a slick deep grey and gloss black look, these cans are largely the same headphones as the HD600 model but with a few quite noteworthy improvements. First and foremost, Sennheiser audio engineers improved the baffling damper for tighter acoustic control, and boy did that work! The lab measurements of these headphones are phenomenally even and jagged-free, and the tonality is probably as close to 'down-the-middle smooth' as is available at this price. The renowned classic Sennheiser sonic warmth has been coupled to a clarity of acoustic detail in the HD650 that is hard to beat by most other audiophile master-level headphones. Design-wise, the earcup grilles on the outside of the earpieces have been made sturdier; those who suffered a dented housing on their old HD600's will likely be appreciative. A new velour headband pad design improves on the already good comfort of the HD600 headphones, and a slightly tighter tension on the earcup adjusters makes for a more secure fit. The HD650 cord has also been much-improved with a better OFC cable design terminated to a full-sized 1/4" stereo plug. A short cable-style adapter to a 1/8" (3.5mm) mini-plug jack is handily included in the HD650 package. Although it's a decent mini-adapter, we still highly recommend getting the superb Cardas Audio 1/4" to 1/8" adapter if plugging the HD650 into a source with small sensitive 3.5mm (1/8" inch) outputs. Overall, HeadRoom definitely more than recommends these fabulous Sennheiser HD650 headphones. Our HeadRoom motto: we say shell out big and cry once, but forever have world-class, blissful audio at your ears!

NOTE: Though the Sennheiser HD650 improved cord is certainly better than the original HD600 stock cable, we continue to suggest the Cardas Audio upgrade cable for ultimate detail resolution, musical texture, instrumental separation and soundstage depth. The significant audio benefits of the Cardas Audio cable upgrade will be especially evident with reference high-end audio sources. Please feel free to buy a Cardas Audio cord and compare versus the Sennheiser cord to determine for yourself the advantages. As always, our standard HeadRoom 30-day return/refund policy with zero 're-stocking' fees guarantees you'll love what you hear!

It's the Pros and cons of Open Seal, annoying for the others, sounding heavenly for you...
What a great headphone indeed!

Headphone that end my searching of Perfect Headphone
Posted by ExCelciuS from Jakarta, ID on 2013-10-20

Recommend Product: Yes
Pros: Comfortable, Dynamic and Rich Sound, Spatial, non Fatiguing yet has clear and clean treble
Cons: Sub bass extension is better on Denon AH D2000

Hello fellas, it is funny that I made switch from AKG K701 to HD 650 because I don't find AKG K701 enjoyable for long term listening session, while a moment ago I've read someone on AKG K701 reviews switch over from HD 650 to AKG K701 because he doesn't feel quite pleasant with HD 650.

So first and foremost of all, in this headphone worlds, if you don't want to lose money is by figuring out what is your sound preferences which you enjoy the most. And then compare that perfect sonic preferences of yours to the sound characteristic of headphone that you will buy.

I found my sound preferences is completely fulfilled on HD 650 sound characteristic, they are in order :
(+) Comfortable (all headphone that you will buy should not have comfortable issues and should passed this criteria, it is not fun enjoying blissfully audio while in hellish pain enduring the uncomfortable of your headphone).
(+) Rich and depp authentic bass, full bodied bass, and vocals.
(+) No glares on treble but still has clean and clear treble and vocals. Non fatiguing sound.
(+) Spatial that is on perfect wide and depth.

The cons of HD 650, that I found which is minor for me is I found that the sub bass extension of D2000 is better than HD 650.

So I have found my perfect headphones, note that I've tried the HD 800 but I still prefer HD 650, and just wait for my next purchase which will be Sennheiser HDVD 800 :)

Gratias !

Easy Listening, not for purists
Posted by Bloody Gus from Kosd, Hungary on 2013-09-01

Recommend Product: Yes
Pros: Dynamic Range, sense of space
Cons: Low-mid coloration

I bought these headphones as a step up from the Audio Technica ATH-M50's, 'phones good enough in their own right for their price, but I thought I would have something better, and you have to pay at least twice the price if you want any substantial improvement. I chose the 650's on the strength of their almost universal recommendation from all quarters, despite a few cautionary remarks about veiled lower frequency response. My musical choice is predominantly classical, and I use Etymotic ER-4S ear-canal phones for accurate, intimate, instrumental (mainly chamber) music, with the Big Cans for wrap-round orchestral sound, all driven by a HeadRoom Micro DAC/Amp combo. The 650's arrived nicely boxed, with yards of heavy cable leading to a quarter-inch jack, plus an extra lead for a 3.5mm connection. The phones are comfortable to wear, unless you have an oversized head: there's no way to adjust them. The long lead can get tangled up round your feet, chair-legs etc. Straight out of the box, the phones sound dull, flat and disappointing, as all quality headphones do, they need hours of running in, like 1950's new cars. (A pity manufacturers can't supply phones ready run-in: it means you can't make comparisons between different models, as you can for speakers.) I used JLabAudio to provide a continuous stream of white/pink noise (with minute breaks) to help burn them in - freely available online. After a week, the phones are beginning to get usable. I'm impressed by the dynamics and sense of space they give, brilliant highs and deep bass, with very fast responses and an exciting sense of arousal. I'm less thrilled with low-mid range, which sounds distinctly coloured, not so much veiled as muffled, as though through a blackout curtain. What are they playing those cellos with, rhubarb sticks? Well, this colouration makes for easy listening (Your Hundred Best Tunes etc) but not so good when you want more accuracy and involvement with the music. I did a side-by-side comparison with the Etymotics of an exacting piece of music, a 24-bit FLAC studio-quality download of the Hyperion recording of Richard Strauss's Don Quixote and Till Eulenspiegel, with exposed horn, clarinet, cello and viola solos: and found the 650's totally outclassed for accuracy and presence. Maybe I should have taken notice of those remarks about veiling. The 600's, I now read, have a flatter response and more accuracy, maybe I should have chosen those. Well, who knows, maybe these cans will improve in time ... hope so, they cost me deep in the purse
