SonoCore Bryan COA-803+

General Information

It’s rare to see a dual dynamic driver earphone in the sub $100 range, and that’s exactly what we will be taking a look at today. After reviewing top tiered IEM’s, I thought it would be good to take a step back and look at some budget IEM’s, tailored for all the mid-fi people wandering around on the market. The SonoCore COA-803+ is a dual dynamic driver earphone that appears to have tons of bass, at least according to the frequency response graph. I haven’t heard a lot of talk around these earphones and I’ve seen them only once on SonoCore’s official website and an eBay listing and it seems like this is what appears to be SonoCore’s first ever jump into the IEM market. Oh, and for anyone that is wondering, they are made in Korea, and have some rather unique specifications to them. But we’ll get to that a little later, for now, let’s jump into the review of the SonoCore COA-803+.
