If you’re looking for high-quality sound on a budget, the 7hz Timeless offers very good overall sound quality, a detachable cable, and compatibility with balanced audio cables, making it a strong value pick. However, the Sennheiser IE600, while more expensive, delivers best-in-class sound quality and excellent build quality; it also provides a more comfortable wearing experience and better noise isolation, but lacks a microphone. Both earbuds are wired with no active noise cancelling, making them less ideal for noisy environments or exercise. Choose the 7hz Timeless for a cost-effective balance of quality and features or the Sennheiser IE600 for top-tier audio fidelity and premium build, if budget allows. Give Feedback

"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."

"If you've got the bucks, the Sennheiser IE 600 is a nice, upscale set of in-ear monitors made of a lightweight metal with an unusual texture. It comes with a suite of extras, and performs well at virtually every task."
