Review on 🎧 ERJIGO KZ ZS5 Quad Driver Headphones - High Fidelity Extra Bass Earbuds with Microphone and Remote, Detachable Cable, Blue by Cody Clark

Great value for money. The description/title said 'huge bass' but I would say it's the complete opposite of 'high fidelity'. The additional drivers clean up the high mids and highs, very natural-sounding crossovers and extend the lows without overdrive. Compared to the ZST I'd say they open up the treble a bit more which is lacking/darker on the ZST, the bass doesn't hit your eardrums as hard which might be less appealing to those comparing it to the more powerful in the beginning Hits on the ZST, but the ZS5 is absolutely bass-heavy, falling steadily to 40 and 30Hz and sounding pretty good. The fit and finish of these headphones is way above the ZST and I just don't think you can find better headphones that sound as good. We use both the ZS5 and ZST as in-ear replacements for the Shure SE215 on our stage, and for the money I personally would have preferred the ZS5 to the Shure SE425.
