Like it wasn't even there. Vocals didn't really seem any better, either. I do like the sound on my DT880 but it will take some getting used to with my HD650.

 

That statement is quite nebulous. What are they? Where were they made? Era? Getters?

PQ labeled OG's? Odd.

 

Are these the ones you're referring to? These A-frames are the ones I recommend, though mine were manufactured a few years earlier. If those tubes don't do it for you and you require a more balanced presentation I'd suggest checking out the Bugle Boys. These have better clarity and a more open soundstage than the OGs, but I found them too polite for the HD650. Awesome for the HD800 though.

Just bought these on sale at Amazon for $400!!

I'm so excited! Should have them by Tuesday :)

Anyone know what to look for to see the differences between the old ('veiled') HD650s and the newer 'non-veiled' 650s? Something about a white screen but I have no idea.

Yes, the scredn behind the grills are whte. The old ones are black. Its obvious, really. Google some images, you can clearly see the difference.

Oh I see, thankyou MLE, the screen being the material on the baffles and not the grill, I was a little worried as the model I recieved has a relatively lower serial number (109808) compared to others I've seen. Here's my pair:

You're definitely good to go.

Hi! This is my first post in this thread. I have had HD650 for a couple of years now and I really like them. I have the old version with black drivers. Would it be worth it to upgrade drivers to the new ones. I can get new drivers for €100. Anyone here who really heard that difference in sound between the two?

post #10124 of 27626
Do any of the HD650 owners regularly equalize their set? If yes, then what are your settings?

The difference is the damping material used on the baffles as MLE confirmed, so if you do get new ones make certain it's the whole baffle/driver and not just the capsules. From what I've been reading this morning some say there's a definitive, large difference, the new material un-veils them, makes them brighter and more controlled, with more consistent sound between batches of HD650s. Some say there's no difference, very mixed opinions.
