If price is a major factor, the KZ ZSN Pro X earbuds are often significantly less expensive than the JBL 510BT headphones and provide good overall sound quality. For on-the-go listening and portability, the KZ ZSN Pro X earbuds are more practical. They also feature a detachable cable and are well-built. However, if you enjoy the convenience of wireless audio, prefer the on-ear form factor, and value features such as built-in controls and longer battery life, the JBL 510BT headphones may be worth the extra expense, although they offer lower comfort and sound quality for music. Neither option is ideal for gaming or watching TV due to poor performance in these areas, and if a microphone is important for you, both have good mic quality, but the JBL has an integrated style which might provide a more unified experience compared to the cable ear hook style of the KZ.

"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."

"The KZ ZSN PRO X offers superb sound for very little money, like under $30 USD. It has some rough edges with a plastic seam on the cable that can rub on your ear, and the bud is a bit large. The tech isn't cutting edge, but new doesn't always equal better. You should try it."
