If you prioritize overall sound quality and soundstage for activities like music listening and watching TV or videos, the Audio Technica ATH M40X outperforms the 7hz Timeless. Despite being older and more budget-friendly, the ATH M40X also offers a more comfortable over-ear design suitable for long sessions. The 7hz Timeless, however, excels in music with a higher score, making them a good choice if music fidelity is your main concern. They are also more portable than the ATH M40X. Neither have microphones or active noise canceling, so consider these points when making your decision based on your usage and budget. 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."
