As with other wood earbuds we've listened to, the Rain earphones offered a more natural and open sound during testing. However, these don't offer the resonance that we experienced with the Woodees or even the Thunder headphones, this is likely because of the different shape of the earpieces. Also, we felt that while the Rain earbuds offered crisper overall sound and more details on the high-end, the low-end audio seems to be lacking, especially when compared with the Thunder's. Doubtless, this has everything to do with the smaller driver size. The overall result is audio that sounds cooler than warm, which is not something we prefer; however, some listeners may feel differently. The upshot of the small driver is that we didn't hear any distortion and the sound it produced was very clean.
Overall, we found it produced audio that favors the high-end with a recessed bass response that makes the mids seem overly forward at times when listening to music. We enjoyed folk, oldies, and classical genres when listening with these buds. If those are the types of music you tend to like, the Rain is a solid option, but only if you can find them for around $60 rather than $100. They're not a good choice for people with more eclectic music tastes.
