and thats why we spend 15$ on a KZ iemMaybe quit buying KZ or chifi as a whole? Actually, this borderline addiction isn't even a problem exclusive to chifi. You'll get a select few who are flush with cash and want every TOTL IEM ever. There's never an endgame.
Also, I understand it's tempting at the price, but KZ doesn't even pack an assortment of tips beyond the bare minimum, so that should signal to you that they're not paying much attention to detail.
Call me cynical, but personally I'm not expecting attention to detail from KZ at this price.
If you're buying entry-level chifi, you're pretty much diving head-first into the bargain bin so enter with caution, be prepared to be disappointed, and you'll be a happier person when you get something nice.
If you want fewer issues, consider buying locally, demoing the sound, paying a slight premium, maybe even taking the leap to mid-level IEMs for more consistent performance.
I'm just saying, KZ exists to make money, you exist to enjoy the sound of their product. If you stop enjoying their product, maybe it's time to stop purchasing?
we get the best sound for 15$ at that time
but spending 40$ or 50$ on KZ would be a big no because they don't have the best QC and after sales service i would better off buying well known non chi-fi brand's iems for consistent QC and after sales service
i remember buying a senn cx180 in past and got it replaced like 4 times in 2 years and had a huge stack of its tips although that iems sucked but i got like 12 pairs of tips not too shabby lol
