Choosing between the 7hz Timeless and the Sennheiser HD800S depends on your priorities. If you want top-tier sound quality, spacious soundstage, and exceptional comfort, and don't mind the higher cost, the HD800S is a great choice, particularly for critical listening and immersive TV and video experiences. On the other hand, if you're looking for a more affordable option that still delivers excellent music playback with good sound isolation and portability, the 7hz Timeless is a strong contender. However, be aware that the HD800S may have a competitive edge in build quality and durability, and the open-back design offers a superior soundstage, which the Timeless, being earbuds, cannot match. Neither option is ideal for exercise or noise-heavy environments, and neither offers wireless connectivity or active noise cancellation. 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."

"The cans offer stellar sound quality, comfort, and good maintenance options—so they're an easy recommendation if you have the cash and the need for the last headphones you'll buy for years."
