Sennheiser HD 650
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.

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!

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
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 :)
