I found the 660s used for $240.00 or $220.00 for the drop 6xx any opinions on what might be my best best for quality of music? Thanks!

The 300-Ohm Sennheiser/Massdrop HD6XX are something I would use with a tube amplifier or A/V receiver.
Were as the 150-Ohm Sennheiser HD660s would be easier for a smartphone to drive, but should work well plugged into a lot of head amps.

I have the 6xx phones I run from preamp record Jack's to a Liquid Spark headphone amp and was curious if the 660s phones might be an upgrade? Thanks

It's tad cleaner sounding but less smooth.

Thank folks, I have the guy talked down from $245.00 to $200.00 but, am debating if I should buy them or, maybe a little better headphone amp? The phones are like new one month old.

The 660S comes with two detachable cords, one single ended and one balanced. If you have a headphone amp with a balanced output, that could be an advantage.

 

[crippledchicken]

I'm pretty sure I don't have a balanced output but, I may get one l'm suppose to go pick up the 660s in the morning and I'll post back after listening.

 

[crippledchicken]

Another amp with balanced output I meant to say.

I got the 660s and have them playing on cd player on repeat for some burn in time what's good music style for this? Thanks!

If it's just music, the 6XX is much better imo. If you game and other stuff, the 660s is better all arounder.

With my ears, the 660s seem to sound cleaner and have more definition especially on cymbals and high hats. Of course this could be due to my age. I'd like to have a head amp with L-R balance control since my left ear is a little better than my right. I must say though, the sound of the hd 6xx and the 660s are both very satisfying. I mainly, need the balance control and both pairs will probably exceed my expectations.

I agree with that. I think the 660S is superior for music, but obviously these things are a matter of opinion in most cases.

I agree, to me they sound cleaner that the 6XX. The 6XX has always had that veil that people write about. I know there are amp pairings that improve the situation, but I never had that with the 660S. To me the 6XX do sound smoother, which counts for something. At the end of the day, neither really did it for me. But if I had to do it over again, I'd probably go 6XX and try to EQ them.

 

[Mark200]

That is a good deal. If I were in your shoes I will jump on the offer.

The 660S is now selling new for $300.

 

[Mark200]

Well, a very good used one should sell around $200-$250.

The current $300 price is directly from Sennheiser (or from Sennheiser store in Amazon) and includes free shipping. So I think the higher price of new vs used is worth the difference to make sure you get a warranty, and also to provide free 30-day returns if you don't like them.
