Quick review:

The Beta is one of several sub-$100 IEMs from Brainwavz and as with the rest of them (excluding the M4 IMHO), the Betas are an excellent bang for your buck. They offer a more balanced sound than the Brainwavz M2 and M3 which are warm and bassy. The Beta sits close to the M1 in sound signature (neutral but energetic).

The half in-ear design opens up the soundstage but provides less isolation than typical full-insertion IEMs. The fit might seem awkward at first but is easy to adapt to. The build quality is not great even among the budget crowd, but the Beta makes up for it with excellent sound.

Starting on the low end, the bass is solid for the price. Those looking for gobs of bass should look elsewhere but it will more than satisfy the rest of us. Mids are a touch recessed but maintain good detail and clarity next to the M1. The M1 is more analytical and smooth compared to the Beta which is more aggressive and fun (though the M1 is better at keeping up with fast-paced music). The top end has some control issues but at moderate listening volumes this problem does not present itself.

All in all, the Betas merit a high recommendation for the simple fact that there are no glaring flaws in the sound which is pretty uncommon at this price.
