If exceptional sound quality for music is your priority, the 7hz Timeless earbuds are the superior choice, offering better overall sound and a more immersive soundstage. They come at a premium price, and while they don't have a microphone, they excel in construction quality. On the other hand, the KZ ZSN Pro earbuds, while less expensive, come equipped with a microphone, making them more suitable for calls and meetings. They also provide good sound for gaming, and their durability is noteworthy. Both options are wired, with no active noise cancelling, and neither is specifically optimized for sports or exercise.

"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."
