Sennheiser HD 650 Headphones

Just got my Sennheiser HD 650 Headphones in the mail from AudioGon Seller "Glicco". What a excellent set of headphones. Great sound and great comfort.
All the time and money I have spent with my hi-fi with speaker placement, room treatment etc just trying to get this kind of sound. I should have done this along time ago. Anybody else have great headphones they really like?
I lurked into Headphone land about 4 years ago right before my son was born, thinking that I would probably not be able to do much listening to my main system at full level after he was born. (As I do a lot of late night listening.)

I diligently participated in the forums over at and went to all the local meets for a period of about two years. I now own 4 pairs of head phones and 5 headphone amps. There are just as many headphone choices as there are speakers out there. I made a decision early that I would stick with the Senn HD600. It's a great headphone for the money. I got the itch one year, and bought the HD650 for my birthday. Also have a pair of Grado SR-60 at work, and a pair of Etymotic ER-4S for on the road.

I primarily listen to Jazz, and the headstage thing just drives me nuts every time I listen to Jazz. Yes, for the money, you cannot beat what you get out of a good headphone setup. But I'll take a pair of speakers any day.

To my surprise, my son sleeps through most of the time when I play music. Or we enjoy music together. He has short attention span, so most of the time we don't play LPs but CDs. So now my headphone gear just sits there and gets turned on maybe once or twice a month.

The stock HD650 cable is pretty decent, but there are several aftermarket cables that work really well. Check out the comparison over at I personally like the Zu Mobius/HD650 combo. And a decent headphone amp really makes it sing.

On Head-Fi, you'll find different camps when it comes to headphones. Senns are popular, so are the various expensive Grados (RS-1, PH1000, etc.), AKG, Beyerdynamics and Stax are also popular. The most high-end current production model is probably the Sony (I forgot the model). You have to make an appointment and go to a selected store to get custom fitted for a pair that will ding you US$5k. The most desirable is the Sennheiser Orpheus. They are no longer made. If you were one of the lucky ones that had purchased one when they first came out, you can sell them and double or triple the money you paid originally.

Some Great information as always. Thanks guys. I will look into getting a Zu cable.

Yes, the soundstage is missing but seems to be a good alternative when laying flat on your back in bed late at night.

I have these same headphones and they "sounded" great until I changed my preamp to a Lexicon MC-12 which does not have a headphone jack?? Any advice, or am I missing it?
I stumbled into having a pair of headphones when I saw a new pair of Sennheiser 600's on craigslist for $100 and couldn't pass them up. I soon after found a great deal here on audiogon on a Headroom Little More Plus headphone amp. I'm using an Ah! Tjoeb tubed CD player as a source and the combination is very nice.

The Headroom amp has a 'Crossfeed' option that mixes the signal a bit to simulate the more natural soundstage of speakers. It's not the real thing but I find it makes listening to the phones a lot more enjoyable.
Sorry to rain on your parade, but I to really enjoyed my 650s with Cardas cable, right up until the day a got a pair of AKG 701s. After repeatedly listening to both, it got to were I couldn't ever listen to the 650s anymore.

As good as they are, the 701s trounched them is overall accuracy, revealing the 650s sometimes pleasing, but VERY colored presentation, especailly in the bass.
