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.

I had Senn HD580's prior and like the D1001 better due to the low end. They aren't as open as the Senns though. I think they sound good without an amp.

I have both the D1001 and HFI-580. I like the 580s more for "rock" and the D1001 for acoustic music. To me the D1001 are more detailed. But, overall I like the 580s more for their bass extension and fuller sound.

I listen to mine right off the iPod all the time.

I really like my HFI-580s. I haven't listened to the 780s for comparison, though.

I enjoy my re-cabled D1001s. They are so comfortable.

Can someone tell me the sonic difference?

I have had a pair of used HFI-580s for about six months now and love them! They have been my favorite can so far. What are the improvements of the 780s over the 580s?

There is no need for the plastic ovals.

I'm thinking of re-cabling my Ultrasone HFI-580's and was wondering if anyone can tell me how the sound changed? Better or worse?

The foam could change the sound a bit. Don't be afraid to pull on the ear pads a bit and use your finger to tuck the foam under the pads better. I had to do that for a pair of 7506's I had.
