Zelda provided us with a review with the dual BA driver $199 IEM from Brainwavz. From the review the B200 is a better IEM than the single BA B150 but Zelda believes the B150 is a better value as it is half the price. Personally, I would look into the 1MORE, Easy LZ or even the Echobox Finder IEMs.
Crabdog has a review of the single BA driver B100 over on Head-Fi. For the price (<$60), they sound like a fine set of IEMs.
Pros: Clear and detailed sound. Exceptionally comfortable. Price. Accessories. 24-month warranty
Cons: No inline control or microphone
HiFiChris posted a review of the single BA driver IEM over on Head-Fi.
Pros: non-“sterile/boring” single-BA sound, smooth and musical, good tonal balance
Cons: not too many competitors but those that exist are also good
Brainwavz XFIT XF-200 fitness IEM is reviewed by SoundApprentice on Head-Fi. This is a budget IEM priced on Amazon at $25. Brainwavz is calling it a fitness IEM.
Pros: Compact, lightweight, universal design
Cons: Boomy bass, unrefined sound
