Do either the P9 or P7W have similar sound signatures to the dt 770 80?
It's been a couple of years since I sold my DT770 80, so I'm relying solely on long term memory.
From what I can recall, the DT770 80 sounds a bit V shaped.
It has bass that, literally, rumbles like thunder..when called for. That being said, the bass is kinda loose and a bit sloppy at normal listening levels...and falls apart completely when you crank the volume up to uncomfortably high levels.
The P9 bass is glorious. It doesn't rumble like the DT770 does, but it still goes subwoofer low, hits harder, is much tighter, has more texture, and, in general, is much more refined. It does have a noticeable midbass hump though.
From what I recall, the mids of the DT770 take a bit of a back seat. They sound ok. Not bad, but not really memorable...hence why I'm having a hard time describing them.
The P9 mids are not quite as emphasized as its bass, but they are also not what I would call recessed. Certainly more present than those of the DT770. They are smooth, yet detailed. Very refined, with a tonality that is very realistic, for a closed headphone.
I don't recall much about the highs of the DT770, except that I believe that I found them metallic sounding.
The P9's highs are detailed, with just a bit of sparkle, and a good, natural tonality. Not a bright headphone, which also means that it is never harsh and has absolutely zero sibilance.
It does manage to be quite transparent and revealing...perhaps amazingly so, considering that it's a closed headphone with a powerful bass response. It is substantially more revealing than the DT770.
I believe I remember the DT770 having a good, fairly wide soundstage...for a closed headphone. Also decent separation.
The P9 soundstage is wider, more coherent, and better organized. The only closed headphones that I've listened to that have a wider soundstage are the Sony Z1R and the Fostex TH900.
All this to say that, although they both posses a somewhat emphasized bass response, that is where the similarities end for me. The P9 is several classes above the DT770 in every way, as it should be, considering what they sell for.
The P7 Wireless is also a better headphone than the DT770, but not nearly as good as the P9. I do think the DT770 has a better soundstage than the P7W, and a more enjoyable bass response, if not as accurate (not to say that the P7W bass is very accurate).
