I've listened to FX700 for most of the afternoon and I've e-Q5 in my ears now.
FX700 is slowly growing on me. I have a combo of about 50 tracks covering various genres I listen to. Right from Meshuggah's "Combustion" to Miles Davis' "So what". What usually happens with IEMs is that I get bored and skip a song or two. Today, I didn't skip any of the songs and kept on listening to FX700. There are other IEMs that match in FX700 in certain aspects like DDM can match the sound stage width to a large extent. But, none has the overall package FX700 has. It certainly has become my favorite dynamic IEM now. I kept thinking if I had a custom that sounds like this... that can add isolation, extra comfort, longer cable...

hyeah:
e-Q5 is a strange IEM. I loved it when I first got it. Yesterday, I tried it for a while (with Clip+), searched left and right for treble, got bored and thought it sucked. Today, with S9, it plays along nicely across the spectrum. In this short session at least, I feel it's more closer to a dynamic IEM than a BA. It sounds decently well balanced. The bass does have a decent body and texture, but lacks the impact. It certainly feels better than something like a RE-252 (A/B pending). Mids are of course good, a bit too smoothened for my liking at times. Treble has decent sparkle, but never offensive or sibilant. Give it a vocal track, it stomps on other IEMs and then some. Overall the signature is enveloped in a cloth of smoothness.
I am yet to get my head around the sound stage. It has a good height, narrow depth, decent width. A few times, I hear things a bit deeper. Other times, the sound stage has two rows - forward and very forward and things that happen between them. May be it changes as per recording? Get this - Opeth's "Closure" (Damnation) has drums at 1:35. In FX700, the drums come from back to the front like a football being kicked. In e-Q5, it comes from forward to more forward and it feels more like a basketball shot. Right now, Miles Davis' "So What" has the drummer sitting on my right ear and Miles Davis (or is it Coltrane?) standing and playing a little above and to the right of my left ear. Nice!! RE-252 has a similar issue, but it stretches the information across in a lateral plane forgoing depth almost at all times. Both are a bit odd in a way.
