The 7hz Timeless earbuds may suit you if portability and a more enclosed listening experience are important; they're generally less expensive, have a solid build, and deliver great music quality, but they offer limited noise isolation and are not recommended for exercise. On the other hand, the HifiMan Sundara headphones provide a superior overall sound quality, better comfort, and an exceptional soundstage, ideally suited for an immersive TV and gaming experience, though they are less portable, have an open design that lets sound in and out, and may be somewhat more expensive. Neither option includes features like active noise cancelling or wireless connectivity. 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."
