If you prioritize wireless convenience and longer battery life for activities like exercise or travel, the JBL 510BT headphones might suit you better, despite the higher cost. They offer active noise cancelling and are foldable for better portability. On the other hand, if you're seeking better sound quality and build for a lower price and don't mind a wired connection, the KZ ZSN Pro earbuds are a compelling choice. They also have a detachable cable which could be a valuable feature for durability. However, the JBLs' have built-in controls and are optimized for quick charging, features the KZ lacks.

"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."

"Undoubtedly the focus and the star of the show, the ZSN Pro’s bass is big, bold and bangin’. The amount of gusto in the low end should satisfy anyone who likes a large lick of bass and even certified bassheads will probably get a kick out of this."
