If you're weighing the 7hz Timeless against the KZ ZSN Pro, consider the following: The 7hz Timeless is usually more costly but offers a premium audio experience with detailed sound and wide soundstage, ideal for critical listening. However, they may not be as versatile for everyday activities due to the size and may require an amplifier for the best experience. On the other hand, KZ ZSN Pro is more affordable and can offer good sound quality for everyday use with easier portability. They may lack some of the audio refinement of the Timeless but are more straightforward for casual, on-the-go listening and less demanding of your audio source. If cost is a concern and you seek good general use earbuds, the KZ ZSN Pro could be sufficient, but if you're after high-fidelity sound and are willing to invest more, the 7hz Timeless might be the better option.

Kazi Mahbub Mutakabbir | May 2023
"7Hz picked a bold name for the Timeless and frankly, got very close to justifying their word choice. Most importantly, the Timeless are good to go in stock form, so you don’t have to worry about source-matching and such. I can recommend the 7Hz Timeless to those who do not mind a dash of brightness up top, want a taste of planar in IEM form, and want one of the most resolving pair of earphones in the $150 - $300 price range."

"Undoubtedly the focus and the star of the show, the ZSN Pro’s bass is big, bold and bangin’. The amount of gusto in the low end should satisfy anyone who likes a large lick of bass and even certified bassheads will probably get a kick out of this."
