Review: Sounds most like AR-3a to me. I prefer the sound of dynamic driver IEMs to all others. - Sound is a personal subjective experience. In my journey, I started with the expensive brands (before chi-fi iems exploded) with all different types of drivers: BA, planar, electrostatic, and dynamic. Right now, I can buy several pairs of chi-fi sets for the price of one of the other brands. UE (before logitech buyout), Etymotic, SHURE, Klipsh, and Sony were the brands I tried. After that, I tried a brand called 1more. After over 3 dozen pairs, what I finally found out is that I prefer IEMs with only dynamic drivers. This one fits the bill. It sounds to me most like the speakers I listened to growing up - which were mostly AR while they were still AR in the 1970s. Again, music is very subjective and it seems like my preference has converged on IEMs with 2 or more dynamic drivers per ear and no other type of driver. The brands I tend to buy are CCA, Kbear, Revonext, and TRN. The TRN V90s were my goto pair until I saw these dynamic only multiple driver models. I bought every pair that was multiple dynamic drivers under a specific price point. This model was one of them. These sound most like speakers to me and all 2-3 dynamic driver models I've listened to fit the bill and I regularly use all of them. The difference is really in the shell construction and the presence of the dip switches for passive EQ. For gaming, I use very light ones with transparent plastic shells and no dip switches. If I want to monitor a vocal performance, I'll use this model or one like it. These sound most like the AR-3a that I listened to during my younger influential years and I suppose, my brain think that's the way things should sound. I still have the speakers, but they are heavy and huge and really difficult to drive - so they stay in the basement. For my home theater setup, I use the smaller speakers (dynamic woofer and dome tweeter) and a sub. But the AR-3a and these iems still sound better, except the ARs and the IEMs are only 2.0.
Review: Impressive for the price - Ended up getting the Bass version and was fairly impressed with what I had received. I wasn't expecting much from what the price is but these are very nice sounding. The Castor's have a sleek look to them and they fit very nicely in the ears, I get no pain from them. They feel durable and made out of good materials, These are for sure the best entry level IEMs I have seen on desertcart. The mic isn't impressive but at least there is an option to have one or not.
