REVIEW: HFI-580 vs. PRO 900 vs. DT770 PRO 80 comparison - Page 3

For anything with mechanical components (speakers) break-in is clear and measurable.

Here is an example for some Audax driver. Vas changed the most, which one would expect.

Anyone with speaker building experience will tell you that you should not measure Thiele-Small parameters until the driver is thoroughly broken in.

Electronics are more debatable (though capacitors can change in value with voltage applied over time) and cables more debatable still.

For drivers though it is not debatable. The differences are easily measurable.

But, but....HOW DOES THE BASS COMPARE TO THE XB500!?

Haha just picked some up from best buy to get a better picture of what i want in my headphones and was looking at these, btw would also liek to know about the Audio Technica 700 Pro MKII which is anotehr bass monstaa.

Seriously though, anyone compare any of these's bass or at least SQ to the xb500? Pleeeeeeease :) 

DT770 PRO for 170 dollar OR 900's for 305 dollar... What should I do?

wow, nice review！ I　had hfi 580, m50 and tried the 770 80ohm, my feeling matches ur review except the brightness on 770 is too much for me

The ones I have are my second pair as I sold them after getting D7000 then missed them so much I bought them again

Hmm.... thanks
