If sound quality is your priority and you don't mind spending more, the 7hz Timeless offers a high-fidelity audio experience due to its planar magnetic drivers, which generally deliver better bass response and detail. However, if you're looking for something more affordable and portable with a microphone for calls, the Koss Porta Pro may be the better choice. They are lightweight, have a retro design, and come with a lifetime warranty. Keep in mind that the Porta Pros, while acclaimed for their value and open-back design, may not provide the same level of sonic detail as the 7hz Timeless and will leak sound, making them less ideal in noisy environments.

"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."
