If you prioritize overall sound quality and music listening experience, the 7hz Timeless earbuds might be a better choice due to their very good sound quality and soundstage. However, they come with a higher price, a wired connection, and do not support features like a built-in microphone or wireless connectivity. On the other hand, if you're looking for a more affordable, wireless option with longer battery life and features like a microphone for calls, the JBL 510BT headphones could suit your needs. The JBLs are more suited for portability with their foldable design and on-ear form, but they might not match the audio fidelity of the 7hz Timeless. Consider also that the 7hz Timeless may be better for static listening environments, whereas the JBLs could be more versatile for different situations, despite their lower sound and build quality.

"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 JBL Tune 510BT is affordable and compact, making it a great companion for a commute, so long as you don't need active noise canceling. If you wear glasses or have ear piercings, the on-ear design might not be comfortable, since the ear cups will squish your ears."
