Been testing out the SonoCore COA-803+ Dual Dynamic Transducer IEM's extensively. I'll do a quick sum up of the sound in case anyone is interested.
Now that we have everything else out of the way, let's talk a little bit about sound, which will be quite short since this is a budget IEM.*I wasn't expecting a lot from a $90 earphone, but I wasn't under-impressed either by SonoCore's attempt at the budget IEM market. The sound signature of the Bryan is bass centric. Bass was forward, warm, and had a decent amount of boomy-ness although not enough to be overpowering and bloated. Fun is the best way to describe bass with a tiny bit of texture, and low end rumble being highly present and extension being okay with a slight bit of roll off around the 15-20 hertz range. Attack and decay are pretty subpar and are accompanied by a pretty slow speed.*The midrange, just like the bass, is warm and slightly muddled when bass is present in the background.
It also seems slightly thick and maybe a tad bit laid back. I also noticed a slight peak in the upper end midrange around the 1.6 kHz region on the frequency graph. The treble response is decently extended but overall flat with no obvious peaks or dips, where there seems to be no sibilance or bloomy-ness ever present, and while it doesn't exactly have the best extension in the world, they actually had a pretty good range in them up in the higher frequency levels for a $90 IEM. The best way to describe the high frequency response is warm and smooth, and not even entering near the cavern of being bloomy or analytical. Soundstage was pretty subpar as well with separation, width, and depth being slightly congested.
Overall, I have mixed feelings for the SonoCore COA-803+. While I do like the fun and bass centric sound that the Bryans offer, to my ears, it definitely does not match up with its price of $90, as you can find a much more detailed and just as bass centric IEM like the Meelectronics CC51P that retails for the same price. You can pick up the SonoCore COA-803+ for the price mentioned above on SonoCores website. Hit up the link for more info.
