I got my shipment yesterday. The order was right, only the weight shown on the package and tracking info was wrong. It said 61 pounds on the package, like it did in the tracking info.
These were an anniversary present for my wife, but I got to listen to them for about 15 minutes last night - after my wife listened to them for about 10 minutes. We both loved them.
Just a quick impression from listening to them for such a short period of time:
The highs and mids are very nice on these. The music was not veiled at all while listening. It was very clear and enjoyable. There was no hint of sibilance or harshness with these. The mids don't seem to be recessed on these at all (the highs either), so my music sounded full and fairly fun. Male and female singers sounded great on these. The highs and mids didn't sound like they were forward on these either, so these are not right in your face either.
The bass was nice. There was more bass than I expected there to be from other impressions that I have read. Still, it's not a ton of bass, but the mids make up for it. The bass that it has though is clear and punchy, and doesn't get in the way of the great mids on these IEMs. Even with the bass at +3 on my Rockboxed Sansa c250 that I tried them out on last night (no amp used) the bass was still great on these. There wasn't a huge increase in bass quantity with the bass at +3, but it gave them a nice boost and added to the fun factor a bit. My Custom 3's have a ton more bass than these, but the C3's also seem a little veiled to me. Still, these probably wouldn't suit a basshead.
As for their design, I really liked how small they are. The ends of these, when inserted with medium Sony Hybrids, were just about flush with the outside of the parts of my ear right near my ear canal. I thought that was great. The cables on these are semi-rubbery and very flexible. I doubt that there would be a problem with microphonics with these, but then again I didn't do any running around or jumping jacks with these last night around 11:00 PM
My only concern with these would be that there isn't really a proper strain relief on the plug of these. The cable just comes out of the plastic on the straight plug. I can see the cable failing at the plug before anything else goes wrong with these. Well, I could see the cable failing at the IEM's if you pull these out of your ear by the cable. There isn't much of a strain relief at the IEM housing on these. And these things are so small and the housing goes so far into my ears that it's hard to grab the housing to pull these out.
One more thing to add: these seem to be fairly forgiving for poorly recorded/mastered tracks. I listened to one song that I know doesn't sound very good on my Custom 3's (they aren't very forgiving with track quality) and it sounded spectacular on the 700's. After I heard that track I really wanted to keep listening to them for a while longer, but I had to give them back to my wife.
A quick note on the highs with sibilance: I tried these out with rock/alternative music and, like I said before, didn't get any sibilance. I didn't get a chance to test them with any music that I know to be very sibilant, so take the sibilance comments with a grain of salt. I'll try to listen to them again, if I get the chance, with something that's known to be quite sibilant and see how they do with it.
If these are ever on sale for $70 again I'm definitely going to pick up a pair for myself to have as a backup for the DBA-02's that I have back-ordered, provided that I like the DBA-02's.
