I think they both have the same extension into lower freq. The 580 has a bit more impact but I think the 780 has cleaner bass. If you want good raw, deep bass go for the 580.

I got my 780's a few days ago. They are awesome! Just the sound I was looking for.

Oz's prices are a bit high. Check out amazon.com.

The Beyerdynamic 250 ear pads fit well on the 580, 680 and 780 cans. They do change the sound a bit, though.

Has anyone done a recable yet?

I had Grado SR125 and did not like them at all for rock. They didn't have the bass impact nor did they go deep enough. Very detailed and open soundstage, though.

Yes, Ultrasone.

Anyone out there listen to these cans?

Yeah, I wish the highs were there a little more, too.

Try an Ultrasone headphone. I have the HFI-580's and love them. Awesome for metal and rock.

Denon 1001 headphones are about $100 and sound very good.

I really enjoy my Ultrasone HFI-580's. Great bass extension and impact.

I look forward to trying these out.
