I would like to thank Brainwavz for the review sample of R3!   Brainwavz R3 is a dual dynamic drivers IEM. It has 2 dynamic drivers in each housing, facing each other into a sound blending chamber. R3 maybe the only IEM I know to use dual dynamic drivers in this configuration. Frankly, when I saw this configuration at the first time for IEM, I'm quite skeptic. I believe best sound for IEM configuration is to place the driver to face eardrum directly, as close as possible, without any nozzle or sound chamber. I'm a huge fan of Front Mounted...

Hybrid 3 ways: 2x Balance Armature + 1x 10mm Dynamic driver http://www.dunu-topsound.com/DN-2000.html   Update 30 July 2015: I decided to raise the rating to 5 stars after I using it with more players, amps, and DACS, and did more comparisons with other IEMs. My hearing now perceive it as one of the flattest and balanced tonality IEM I've ever used, and no longer slightly mid centric as I perceived before.     I've let around 6 of my friends (non head-fier's) to try DN-2000, without first telling them how much it cost, or what technology...

Hybrid 3 ways: 2x Balance Armature + 1x 10mm Dynamic driver http://www.dunu-topsound.com/DN-1000.html     I was a bit disappointed with DN-1000 when I tried it out of the box. The treble was a bit metallic with the stock silicone eartips. The first few weeks with DN-1000, I used foam eartips, Comply T-500, that smoothen the treble, made the DN-1000 sounds very open and airy, but a bit lacking in bass. Until I did some experiments with more eartips, and found the silicone eartips from my JVC HA-FXD80 give the best sound and tonal balance for my...

    This is my first Brainwavz earphones, many thanks to Brainwavz for the review sample!   When I wrote this review, I have used it for almost 2 weeks, around 2 hours daily. A happy ending journey, that was started with a not so happy beginning.   Out of the box, first impression, S5 sounded bright to me. Rather too bright for my liking. Owning some other bright headphones and earphones, I thought S5 is tuned as a clear and bright sounding IEM. Then i let it burn-in for about 2 days.   After 2 days burn-in, i didn't hear any improvement...
