KZ Castor (Bass ver.) Impressions: Impressively Clean

The Castor Bass Improved, also known as the Black is a set for those who love a lot of subbass and hates midbass. As a matter of fact, this is a must-buy for those who love a Harman-style tuned set with subbass emphasis, not a lot of midbass, and a lot of upper mids to treble to boot. It’s a genuinely fun, borderline bass-head set with a surprisingly clean and open sound for less than $20, but it can definitely use just a little bit more midbass presence. Just a little bit.
