The 7hz Timeless earbuds offer exceptional sound quality for music lovers and come with a detachable cable, but they do not support wireless connectivity, which could be inconvenient for mobile use and they lack features like sweatproofing, making them less ideal for exercise. On the other hand, the Sony WF1000XM4 earbuds, while typically more expensive, provide wireless convenience, active noise cancelling for better sound isolation in noisy environments, and longer battery life, making them versatile for varied environments including calls, meetings, and air travel. They also come with an app that allows customization and are optimized for both Android and Apple devices. Give Feedback

Headphonesty

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."
