Once considered (at least by us!) "The "World's Best", the Sennheiser HD650 remains one of the absolute favorite headphones. This full-size open-back reference headphone delivers silky smooth, accurate sound with a laid-back, mellow tonal delivery. The HD650 is a truly gorgeous can for acoustic music of all kinds and for listeners seeking warm, richly rendered musical detail. Detachable headphone cord makes for easy upgrades to Cardas or CablePro standard and/or balanced XLR cables.

Frequency Response for the Sennheiser HD 650

Click here to see more graphs.

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 headphones has paid off very handsomely over the years. With the HD650, the music is so smooth and relaxed when it's supposed to be; so liquid-quick, so punchy on demand, so effortlessly competent you just fall worry-free into its lovely sonic embrace. Such a great thing is the Sennheiser HD650. The warm yet refined and impossibly seamless sound coupled with great comfort has kept this can in the top echelon for years as one of the best headphones available on the audiophile market.

Liveried in a slick deep grey and gloss black look, these cans are largely the same headphones as the discontinued HD600 model but with a few quite noteworthy improvements. First and foremost, Sennheiser engineers improved the baffling damper for tighter acoustic control, and boy did that work! The audio 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 thicker 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!

Top notch for price
Posted by KK from Holland,Oh on 2011-08-19

Recommend Product: Yes
Pros: Comfortable, Sound quality scales well, lightweight
Cons: Slightly dark sounding, ear cups could swivel a tad more

I have owned this headphone for about a year. Throughout the year I have upgraded many components in my audio chain and this headphone scaled very well with every upgrade. This is a very warm sounding headphone and is non-fatiguing. I could listen to these for hours without a problem. Very good value for the price.

-The headband started cracking after a year. Sennheiser is replacing the headband and more free of charge. They said the issue has now been corrected. Sennheiser is very easy to deal with, so far A++ support.

Don't hesitate to buy this!

Manufactured Auditory Happiness
Posted by Goomphy from Michigan on 2011-07-28

Recommend Product: Yes
Pros: Clean, distinguished, beautiful sounding
Cons: None

I upgraded from HD555s to these little wonders. What an amazing set of headphones. I'm no expert but I know I've never experienced audio at this level before. Clean, precise and effortless reproduction. Expensive for my budget, but worth every penny. I'm very fortunate to have these. Compared to my HD555s, they are a huge upgrade. Vastly superior. Buying here was a pleasure as well. Very fast shipping, excellent packaging.

Still the best audio-based purchase I've made in recent years
Posted by JR from Corona, CA on 2011-06-14

Recommend Product: Yes
Pros: Comfortable earpads, open-back for lengthy listening
Cons: High impedance, cord is a bit long

These were an upgrade from HD-280s and wow, what difference! Of course, you'll need an amp (with a crossfeed filter is a big plus!) to properly drive these cans, but it's well worth the additional cost. Though it doesn't really sing for all musical genres (i.e. rock, electronic), it has a lovely, warm sound that helps when listening for long periods of time, and is not fatiguing at all, especially if you can hear "mistakes" in audio production. It's okay with movies, though it is fun with some Dolby Headphone decoding in the mix. It's about time for some new earpads and a cable upgrade (I've rolled my chair over the cable, which is quite tough, though it will eventually wear down) to make it last a lot while longer. I haven't heard the HD-800s, but I wouldn't mind if I had the HD-650s as a lifelong companion. A definite must for headphone lovers of all kinds!
