  Just ordered for $249. Can't wait to hook 'em up with RSA 71-B.
So far, IE80 was keeping me busy. Let's see how Sony compares with Sennheiser.

Lol. I didn't realize how flat these were.

Awesome! Wonder how you pulled this little stunt!!! *very impressed*

I love a chance to hear these, but I don't think I'd be willing to buy them outright without an audition. I already have an expensive pair of IEMs, so maybe if I see a good deal on a used pair.

It's not completely flat but 7550/ex800st is flat-ish among _single_ dynamic driver IEMs out there. 
 
I'm still debating to myself if I should upgrade to ex1000... but is the ex1000's treble really that bright (or in some cases... painful) according to current & formwer owners? 
 
But right now I'm real content with 7550's sound.  To me it sounds reference grade when I feed it CD or HD-rez modern/current  top-40 music.

Once an EX1000 owner long ago.
I didn't feel that the EX1000 was very bright overall. The main issue I think is the strong peak in the low treble, there are a couple of little peaks too, less problematic. The big peak drove me crazy, but I think I listen fairly loud.
 
For comparison, when I demoed the 7550, I didn't think it was that neutral. It sounded too dark, almost like someone had applied a general cut to the treble of the ex1k. There is still some relative rise in the lower treble, a resonance that throws off the tone.
The high treble extension of the EX1000 wasn't impressive, but the 7550 was disappointing.

The music that's being churned out these days (http://www.youtube.com/watch?v=nFQBv9gD-RU) MDR 7550 with some treble cut off is a god send. 
 
The sound profile of 7550 makes me think was intended as a monitor type IEM :
1. for vocals with some slight bump in mid-highs (typical of Sony monitor-tier headphones that started with the MDR V6/7506)to bring out well defined consonant sounds.
2. for dissecting bass notes 
3. for top-40 tier music.

How long do I need to burn them in

I have ex800st and I agree with most of your opinions, but I don't think it is good at female vocal. 
I think this is the IEM make you enjoy your musics.

I'm not a big believer of burn-in, but 50hr seems reasonable.

Of course. You do not have to agree with me. Vocals can be bit sharp and grainy.

Would anyone here be willing to lend their 7550? , I'd like to see for myself how it compares against some other earphones

Is there a way to eq the Treble spike that you are referring to? It's making my ears ring

 

[Fidelity King]

Bump on my request anybody?

 

[DooberKnob]

Would you guys consider this a good upgrade to the gr07?
