Paid $150 for mine. Used they are alright on price/performance, similar to how I'd never pay $400 for a HD600, but for $200 used they are fine.

I recently ended up with these due to loving the comfort, and then when I started using them, I found that the sound is actually pretty great - for the price. I got mine really cheap (100something) so it was a steal IMO.
think I'll be staying with these for computer use for as long as they last.

FR really does look like what I imagined it to be, I was hoping for them to come up here some day. great job! thanks a lot!

How does that valley in the top end respond to EQ?

August 17, 2014 pricing for "open backed / dipole rad." headphones


HD558 $122 (Amazon Prime - special right now)
MA900 $224 (Japan Collectors through Amazon)
SR225i $249 (mystery company through Amazon Prime)
HD600 $360 (Amazon Prime)
AD2000 $450 (used)


I'd say pricing is appropriate as long as you can deal with the bass roll-off. Maybe find MA900 for less at eBay?

They were sold new around $139-149 one year ago on ebay. I believe paying below $150 is OK but for more you can get better headphone... Just interested how AKG K612 sounds, Since Q701 have very clear bass without audible distortion for my ears I think 612 would be very promising.

Q701 have even slightly clear bass then my DT880 (600 ohm) and both are better in this area then HD600 HD650. Unfortunately every open back headphone I have tried have some significant flaw.

The pair I got was distorted. It just simply could not play even at moderately loud volumes before farting

I think this is a little subjective, haha. I've been able to make them distort only at incredibly loud volumes. But yes I think do distort at a much lower SPL than say orthos.

Get the VST adapter for F2K and try the EasyQ plugin.

I just remembered something about this headphone; is it unique that they have resistors inside to regulate the input wattage? I assume that this is their purpose, something like what the TDK BA200 has.

There's a member on the other forum saying he performed some sort of mod that made the headphone sound better:

After: http://imgur.com/vtUHR&Ie0NN

Personally even with the knowledge, I'd leave it as is because that's obviously what the headphone's designers intended for the headphone's sound. I'm not sure how removing might affect the sound, and if has anything to do with the relatively low SPL levels the drivers are capable of before distorting.
