Typing this while listening to my hd650's which I have owned for 8 years. Previously I had hd580 for 15 years..guess I am a sennheiser guy.

I've always been curious about Sennheiser headphones but have never had a pair.
This thread pushed me off the fence.

I went with a pair of reconditioned (whatever that means) HD650 and they're a really good pairing with my Woo Audio WA6.
As previously mentioned, the soundstage isn't especially wide or deep but the sound is pretty well balanced from top to bottom.
I'm not sure how many hours these have on them so it's possible they just need some more time on them.

I've used Grado SR60, AKG 701, Beyerdynamic DT990 and Beyerdynamic Amiron Home with this Woo amp and these Sennheisers are the best pairing.
The Grados sound fine but they're built to a price, the 701s had a thin sound, the DT990s were quite good and the Amirons are too bass heavy for this amp.
I'll have to try the Amiron on some solid state gear, I think that's what they were meant for.

Thanks to one and all for getting me to stop thinking about them and actually doing something!

Reconditioned is refurbished.
I believe they chaged the 30mm driver, the HD800 used a 50mm driver.
An HD800 reconditioned would be cheaper than the usual $1500usd.

I'm pretty sure reconditioned simply means new ear pads in this case.

Who sold them to you?
I unknow they are selling refurbished Seenheiser.
They are so expensive new anyone can profit on it.

[SteveFord]

You can order them directly from the manufacturer's web site.
Products that have been tested, checked, and thoroughly inspected to meet the same high-quality standards as our new products, it says.

After a few hours use, the soundstage improved quite a bit.
Freo-1 did not steer me wrong.

Wow Seenheiser are doing the same than HifiMan.
If you use balanced cable the soundstage will increase a bit.
HD600 x HD800 drivers:

[SteveFord]

I've put about 8 hours on the HD650s so far and the sound has really improved, stronger bass, better soundstage, the midrange and treble just sound right.
I finally found the perfect match for the WooAudio WA6.
The search is over.

Does it make a big difference for the sound quality using a balanced cable for HD600?
 

I've been a headphone enthusiast for many years.  For what ever reason, I never had bought or listened to the Sennheiser HD 600 headphones. 


I recently corrected this obvious oversight.  Bought a pair of HD 650's recently.  To say I was surprised is a understatement.  I've had headphones costing up to 1500.00 that didn't sound this good.  Easily one of the most neutral sounding headphone I've ever heard.  The only knit against them is that the sub bass is low compared to other headphones.  This is not a big deal for most music, unless you are a bass head, in which case, look else ware.   Otherwise, these headphones may be all one needs to enjoy music for long listening sessions.  They are very light, at 260 grams, and well built.  Many people have owned them for 20 years or more. 


I was so taken with the HD 650, when I saw a sale from Amazon for the HD 600, I had to get them.  They are slightly different sounding, but share a very similar house sound.  The HD 600 is a bit more analytical, whilst the HD 650 is a bit warmer and more forgiving.  The differences are slight, but noticeable. 


The sound can be further improved by using Sonarworks Sound Reference S/W for headphones.  It provides a small amount of EQ for the 600 and the 650.  Combine that with PGGB-RT via Foobar2000, and one can get very high quality sound from a reasonably priced set of headphones.
