Just got my Brainwavz B2 and find the details better than my S4i. Compared to my HD 598, obviously they are not as wide, but they are deep, a bit wider than my ATH-M50. They do sound pretty bright, perhaps even lacking in the depth of the sound, but much more tolerable than the R1s. The harshness/sibilance don't seep into my ears too hard, but after listening to a track that presents a bit of sibilance, it does get quite fatiguing. Most instrumental tracks sound fine, sibilance from vocals are controlled as long as the volume isn't too high, it's not...

Overall, I find these headphones eh for it's price. Comparing them to the Image S2m, they sound more expansive. On depth however, the S2m sound more full at equal volumes without an amp or EQ. The R1s lack clarity and quality when compared to the S2ms, but at higher volumes, can make up for their loss of depth, and with extra spacious sound, immediately become more deep. Bass is strong, sometimes even distorting the music, and parts of the mids sound recessed. Although sibilant at times, it's not intolerable. Using the EQ to increase it's mids and...

Exception of durability, it has similar PROS and CONS to Klipsch Image S4 (being decent quality, bang for your buck), but weak bass. Compared to the S4 though, the quality is a bit muffled.

For $100, I am completely satisfied with the earbud's comfort and fit in my ears (guarantee one of the three sizes will fit), the sound quality (compared to so many headphones at the $200 range, including Beats by Dr. Dre at ~$300), and the controls (now I use the Galaxy S2, only the middle button works).   Unfortunately, after 8 months or so, my first one broke due to it breaking between the plastic wires and the jack (wished it would be shaped like an L, making it more durable). Humid, static, and cold weather will also mess up the volume and...
