The 7hz Timeless offers premium sound quality and a planar driver type, which tends to give you excellent audio detail and clarity, well-suited for music enthusiasts. However, they come at a higher price, don't have a microphone, and their sound isolation and comfort are good but not great. Their cable is detachable, adding to durability. On the other hand, the Koss Porta Pro are budget-friendly with dynamic drivers, delivering a warm sound that's also good for music but might lack the detail of the 7hz. They're lighter and more portable with a foldable design, but have lower build quality and sound isolation due to their open design, which can be a downside for use in noisy environments. Neither option supports wireless connectivity or has active noise cancelling. Choose the 7hz Timeless if audio fidelity is your priority and you don't mind investing more, or go for the Koss Porta Pro if you prefer a more affordable option that's portable and still offers enjoyable sound quality.

"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."

"It’s clear to see why these have been such a popular choice amongst listeners for nearly four decades. It’s a charming pair of headphones that delivers a truly enjoyable listening experience and one that I think punches well above its weight."
