While I do want to commend the Polaris for being a fantastic value set, it does not try to reinvent the wheel in any way which isn’t necessarily a bad thing. It's a decently tuned sub $20 set with tuning switches that do more than enough to add variation to its sound that is pretty safe to recommend to most people. While it may have a little bit of vocal intensity and lack of overall refinement, it continues to lower the bar for good audio at a low price.

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.
