great tuning and technicalities if you've got a good selection of tips to try on these. For me wide bore and/or shorter style tips like on TWS work well. Otherwise you may hear way too much energy in the sibilance region like I did.Wide bore tips that worked for me were Azla Xelastic (other Azla tips look similar), Epro EP00 (poor fit for me, but did fix sibilance), BQEYZ black tips (other storefront) probably many others, it seems as long as they are roughly 5mm diameter or more they tend to work well. (BGVP A07 and Symbio are very similar to BQEYZ, so they may work if they fit the small diameter nozzle on the CRA)Short TWS style tips such as Spinfit CP360, or ALXCD / Rayker tips for sennheiser momentum are examples I have that work.I'll rank some more of my IEMs against each other below, but my best IEM is the Fiio FH3 (using Qudelix 5k) and if i hypothetically rated the FH3 as a 9 out 10, the CCA CRA with any of the above tips is a 7.5 or 8 out of 10. the technicalities and detail in the whole spectrum are great, the bass quality and tuning is probably 90% of the quality of the FH3 and bass is the FH3's specialty.Once the sibilance region is under control the technical aspects like detail and resolution perform way above its price. I also have the older 1More Triple IEM with a few mods to reduce the bloated bass and the sibilance region and the CRA is obviously outperforming it.just some hypothetical ratings, since the FH3 is the best I've heard so far, just take these as ratings against each other.9/10 - Fiio FH38/10 - CCA CRA - insane deal if you can find the right tips7/10 - 1more Triple iem [modified, reduced bloated bass, reduced sibilance region, similar to "Crinacle Periodic BE mod"]6.5/10 - DQ6 - (again with the right tip selection)5.5/10 - KZ ZS10 Pro5/10 - Sony MH7554.5/10 - QKZ VK4 (old version, no longer available, new version is even worse)

I got these for my wife to let her test out some Chifi. They sound fine, but depending on what you've plugged them into, you can hear a lot of background hiss. My wife's Galaxy S7 had issues where voices on youtube would be accompanied with a hiss when they spoke. My Galaxy S10 had no issues like this. Plugged into my laptop's dock has a constant background hiss. Sound quality is pretty good, and I don't get any distortion like I did with the CCA C12s. All in all a decent purchase for cheap.
