Well, I have had the new dual dynamic driver Brainwavz R1 IEM's since 7am today....and I haven't been able to put them down since! These are some of the best low cost IEM's I've ever heard right out of the box. I usually have to do a full burn in to hear what I'm hearing with the R1's. The separate dynamic drivers(9mm for the woofer, 6.8mm for the tweeter)have been tuned seemingly "just right". To start with, the nice box came with a ton of extras, including three pairs of normal silicone tips(S/M/L), two sets of bi flange tips(S/L), and a set of Comply "T" foam tips. I used them all and actually found the bi flange tips to fit me best. It also has the great black and red carry case being sold elsewhere on the mp4nation site for $6.00US for FREE...and its a great case, with tons of room and above average construction. The R1's themselves are also very well made, with good quality black and red plastic and solid cords, with a nice sliding piece to help cinch them up nicely. These do sit over your ears, but they are very comfortable for long periods(six hours plus and counting so far).
The sound stage is amazing, almost on par with my Brainwavz HM5's(no joke!!), very open sounding with great stereo separation and almost pinpoint instrument placing. So far I've haven't heard any driver flex, something I was worried about with the two separate drivers and no protection from it like you get from dual armatures. If it's there, I can't hear/feel it. The very first bit of music I chose to listen to, a flac version of YES's 90125, hit me right between the eyes, with awesome sound reproduction. Listening to Jon Anderson at the high end and the great percussion of Alan White at the low end, and everything that Trevor Rabin and Chris Squire added in between, was simply superb. Nothing sounded off in the least, as a matter of fact, it sounded just the way it was supposed to. To say the R1's are balanced is an understatement. I have some pretty sophisticated equipment at my disposal in my studio, and the sound signature is almost on par with my HM5's in terms of the way sound is played back. I would never use IEM's for my music editing, but these would work great in a pinch, and that's high praise for such an inexpensive set of in ears.
Keep in mind that these haven't even been broken in yet....after a full burn in I will report back with the results. I honestly don't think it will make much of a difference, but it's worth doing so nonetheless. I think that many on here would like to see these compared to the B2's, which I own, simply because they have a dual armature design... and to be honest, it's the first thing I did when opening the box for fun. For starters, the B2's cost almost three times plus what you'll pay for the R1's....but the B2's, IMHO, don't have the same openness or all around clarity the R1's have. The B2's can get a little harsh in the upper end, the R1's simply don't do this. The bass response and feel is also slightly better as well. The mids, on the other hand, are better on the B2's. The R1's do a decent job here, but they aren't as focused as the B2's are. Even if your not on a budget, I would choose the R1's personally over the B2's...they are just a better value all around. Dual dynamic drivers are a great idea, much cheaper to produce than dual armature IEM's, while providing a great, balanced sound signature (if done right) that the dual armatures are always praised for. I applaud Razzer from mp4nation.net for including one in the Brainwavz lineup, great job on this dude!!
Summing up, I honestly LOVE the R1's! I have been looking for a long time for a set of IEM's that I could travel with(read: cheap) that had true, honest balanced sound. My look is finally over. I love my B2's, I really do, but they are just too expensive to be thrown in a bag and knocked around daily. They are well made, but I would scream if they got destroyed...not so the R1's. I plan on buying a few pairs to have on hand if needed...it's just the smart thing to do. If your on the fence about going for these at the great pre order price Razzer has up at the time of this post, don't think about it, JUST DO IT. It will be one of the smartest things you do today, guaranteed As always, if you have any questions, just ask and I'll do my best to answer
