Comments about Sennheiser HD650 - Reference Class Stereo Headphones:
Professional Film and Broadcast monitoring. They are very comfortable, you sometimes don't even realize you have them on. The 650's reproduce the entire audible sound range. I listen to sound with very high dynamic range (Close lightning strikes, explosions, jet engines, etc) all recorded with state of the art equipment. The 650's handle these sounds very smoothly and do not collapse at sudden high Db with low frequencies. They reproduce bass like nothing I've ever heard. All this; and I haven't even broken them in yet! (<40 hrs) The only thing I would add is kevlar netting around the cord (I have a cat that likes to chew on cables)

Comments about Sennheiser HD650 - Reference Class Stereo Headphones:
I was looking into buying headphones to do ruff mixes when I am on the road. It was between the AKG K 701 and the Sennheiser HD650. I couldn't be happier with my decision. At first you need to break them in which might take a couple weeks of listening to music. As time goes they get better. I would recommend an external hi-fi amp to use with them. They can't run off your traditional computer headphone jack or ipod. I wear them for long period of time and are one of the most comfortable headphone to possibly wear. I would recommend this product.

One of the best headphones ever, but it is hard to drive. you cannot use iPod or Laptop to drive it.
With an dedicated amplifier, it will be perfect.

Comments about Sennheiser HD650 - Reference Class Stereo Headphones:
I purchased these headphones for use in my sound classes. I really like these headphones and i am able to wear them for long periods of time with my glasses on. Since they are open ear for production sound they aren't the greatest since they leak, in and out. Its hard to tell if what you are hearing is from the headphones or just outside noise. For that i'll just have to buy a different pair that are closed. For my studio classes they are wonderful and i do not have to turn down the volume. Also i'm not isolated from people when they talk to me since I can still hear them...somewhat.

Comments about Sennheiser HD650 - Reference Class Stereo Headphones:
These headphones seem to physically disappear once the music starts. There is no barrier between you and what must have been in the composer's head. Sound is just beautiful through out the entire range of thses incredibly comfortable headphones. I've owned professional headphones before but these Sennheiser's are in a class by themselves.

Comments about Sennheiser HD650 - Reference Class Stereo Headphones:
HD650's being used with Grace Design 902 headphone amp for
classical music monitoring during recording sessions. Far greater
sonic fidelity and image accuracy than even the very best studio
speaker installations. No exaggeration. And, at a fraction of the
cost, plus being easily transportable to remote sessions.

Comments about Sennheiser HD650 - Reference Class Stereo Headphones:
We have been using several pairs of Sennheiser HD650 headphonesas our very best monitoring reference in remote recording sessionswith the famous, restored Wanamaker pipe organ in the Grand Court of the the downtown [...]/Wanamaker store in Philadelphia. The headphones are driven by nothing less than Grace Design 902 headphone amps.These headphones absolutely rival the sound quality from the very best,customized, fixed-place studio monitor speaker systems at a mere fraction of the cost. They render a brilliant, clean sound that reaches way down to the 16 Hz fundamentals (at zero recording level!) that this huge organ so easily belts out at full tilt. Mids and highs with the HD650's are as smooth as silk too.The current project is Christmas music featuring the Wanamaker organ accompanied by the Philadelphia Brass. Brass pickup was by anotherfantastic Sennheiser product, a matched pair of the new Sennheiser MKH-8040 cardioid microphones. You may hear the results this Fall when the Wanamaker Christmas CDcomes out on the Gothic Label. The disc may be available in Macy's stores nationally. Tune in, because every single note on this upcoming album was meticulously monitored by HD650 headphones!Alex Martin, Assistant Recording Engineerdsp Recording/ Chicago

These headphones do make justice to their reputation. After 100h of burning in, they are by far the best I have tried (and I have been listening carefully to headphones for more than 10 years). You should use a headphone amplifier. They are good without one, but brilliant with one. Also, very comfortable.

Comments about Sennheiser HD650 - Reference Class Stereo Headphones:
The HD650 is the best I've ever put over my ears - and I've been an audiophile most of my 60 years. The sound is full and clear (response seems smooth throughout), and their construction seems completely solid. The fit is very comfortable. Worth the cost.
