Tin T2's i had believed at the time to be the pinnacle of what chifi could offer (for the price). It wasnt perfect, it had its shortcomings. Enter kb100's. stock setup, no tip swap, no mods, maybe a little burn in thats required nothing else. this thing sounds like a dream!
Bass, mids and highs all perfecty balanced and on equal footing. bass can be fun when required (edm) and cold as well (jazz or classical), mids are very well highlighted, giving them excelllent imaging capability. soundstage isnt as amazing as other aspects of these in ears, they dont fall back too much either. After having the tin t2, i was in a phase where i was so nitpicky about an iems bass, that nitpicking led me to this, the graphs for the bassline on this is ruler flat.
These should have the appropriate title of "50usd iem killers". I hope they become more well known in the audio market amongst companies previously mentioned and even the giants like sony, shure, rha, audio technica and definitely against chifi comapnies like KZ and TRN. They should learn about build quality from BQEYZ.
These don't need any lengthy explanation, they are just that good. Get them and understand!
