Short Review

“The Hiby Zeta provides some of the most tactile, fun, and energetic bass presentation complimented with a generally uncompromised midrange and an elevated and non-fatiguing treble for its price. Techs are surprisingly impressive for its tuning but suffer in certain aspects because of it. However, it definitely leaves a lot more to be desired for the price with its offerings and technical ability as well as the fact that it fills a niche in a steep price point. A one trick, bass pony if you will. RECOMMENDED WITH CAVEATS”



TOTL or Top of the Line products in any hobby always cater to the most dedicated (or richest) and often depict the pinnacle of what you can get for your money. While not always true, there are some stigmas built up for such products of magnitude. One of these stigmas is a rather safe tuning that aims to reproduce music in the most neutral or reference manner. But today, we’ll be taking a look at a TOTL IEM from a brand known for their music players that defy the usual conventions for tuning and whether they succeeded in creating something different but appropriate for its price.
