If you prioritize high sound quality for music and have a higher budget, the 7hz Timeless earbuds offer better overall and music-specific audio performance. However, they lack wireless capabilities and are not suited for exercise or calls and meetings due to their poor use during exercise score and mic quality. The JBL Tune 660NC headphones are more affordable and include active noise cancelling and wireless features, making them more convenient for travel and everyday use. They fold for portability and offer long battery life, but have lower sound quality and may not be as comfortable for music listening sessions. Keep in mind, the 7hz Timeless requires additional purchase for certain cables to realize their full audio potential. 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."

"The JBL Tune 660NC is the best value you can get from a set of on-ear headphones. There's no companion app so you don't get many additional features, but everything the JBL Tune 660NC sets out to do, it does well. At this price, the JBL Tune 660NC is an easy recommendation for on-ear headphone lovers"
