I might because even though I liked the amount of bass the Q701 has (I think it's almost perfect for me) maybe a little more would be nicer. The treble is sort of concerning me though.
*hurls* It looks bad, but yup, it'll be on my head so I won't notice, although why do they go with glossy finishes now? Sort of looks like cheap plastic (not that I care because it's a $300+ piece of "cheap plastic").
I want the GR07s all of a sudden...
HD600s can be usually found for $300 and the HD650 can be found for $300 used...
Be warned though, the reason this individual was selling them is because of the fit. They're a lot like a custom in that most of it is outside your ear canal itself and it has a weird insertion. The nozzles do move around to help with this though.
But like I said earlier, I'm not selling the HD600s even though the GR07s come close, they still don't have the same timbre or soundstage
My 40 ohm Brainwavz B2s are more sensitive than the EPH-100 and GR07 even though they have lower impedance. (can't remember exactly now)
The Hd600s (300 ohm) are also a lot easier to drive than the Q701s, which only have ~61 ohms impedance If I remember correctly.
