Review on 🎧 KBEAR KS1 1DD HiFi Earphone Headphone with Dynamic Driver & Detachable Cable: Yinyoo KS1 In-Ear Earbud for Superior Sound Quality and Convenience (with Mic) by James Collins

EDX 10/10 pleasant to the ears pleasant volume excellent bass, price very high volume distorted. ZSX 7/10 is uncomfortable in the ears. Concert level of roaring bass guitar and punchy electric guitar, loud without distortion. ZAX 10/10 pleasant to the ears, pleasant volume, pleasantly fluffy powerful bass, loud without distortion. The vocals are always crisp and never harsh on all three models. Great work Knowledge Zenith, salute you. At $15 this is an absolute steal. I'll use them for work and keep the more expensive ZAX safe at home. I can't say anything bad about EDX, it's almost perfect. Good introduction to KZ IEM.
