Well I jumped at the $99 deal and I received them this morning.
A few initial impressions:
-They sound very good all around. The low end is not very pronounced, but mids and highs sound very nice. Out of the iPhone headphone out they're not very bassy at all (No EQ - iPhone equalizer is rubbish), but my Walkman (EQ'd) makes them nice and punchy. I definitely need more time with them to form a proper opinion, though.
-There are some issues with microphonics as expected but I haven't noticed that it's any better or worse than my Shure SE530's so I guess that's not a bad thing.
-I immediately put on the comply T-400 tips without even trying the ones in the box and I really see no need to ever try them. The T-400's give a great seal, and make these the most comfortable IEM's I've used. I wore them for nearly 4 hours straight today and my ears were not sore or itchy, nor did the RE0's get pushed out of my ears (requiring adjustment) like my 530's do. Even lying my head down on a pillow they're very comfy.
-Their high impedance and low sensitivity means there's almost none of the hiss that's present in my 530's, but it also means they're difficult to drive. On my NWZ-A818, a 'comfortably loud' volume for my 530's is around 14. For the RE0's it's a 19. The loudest I'll put my 530's is 16 (music depending, of course, but on the whole) whereas I expect I could go up to 30 (max volume) with the RE0's on and I wouldn't even wince. While I wouldn't say an amp is
required for these, even adding in a Fiio E5 made a great deal of difference. If you like listening to your music at high volume (I do on occasion) these might not be for you.
-The sheathed cable seems tough but I'm a bit concerned nevertheless. It's already gotten into a decent knot (think shoe lace) and I'm not convinced that it won't start pulling apart, a few fibers at a time, with normal use.
-The 3.5mm plug doesn't seem all that sturdy, and I find myself already wishing it was L shaped instead of straight.
All things considered, I'm impressed with them so far at a $99 price point. I'll update with further impressions in the future.
For now, though, I have some pictures. I don't have a good macro lens and lighting wasn't ideal, so you'll have to pardon the blurriness (as well as my faux wood floor
) . Thumbs link to higher-res shots.
The packaging was surprisingly small, and came in a nondescript manila bubble wrap envelope.
Included accessories are a shirt clip, 3 pair black rubber tips, 2 pair clear bi-flanges, replacement filters, and a ~33" (80cm) extension cable (not pictured)
The cord is roughly 36" (90cm) from the plug to where it splits, then another 15" (40cm) to the earphones. With the extension cable, it's about 84" (7ft; 210cm) from plug to phones.
Close ups of the stock tips, no tips, Comply T-400 tips, splitter, and plug.
Some comparison shots with my Shure SE530's
And finally, since there's no easily discernible difference between the left and right earphone, some color coding of my own.
