If you value sound quality and are using them in a quiet environment, the Focal Elex would be a great choice as they offer very good sound and comfort; however, they have an open design which doesn't isolate noise well, so they're not ideal for noisy settings or commuting. They're over-ear headphones, so they're less portable but they provide a more immersive listening experience. On the other hand, the KZ ZSN Pro X is more affordable and offers good sound quality and noise isolation, making them suitable for exercise and travel. They're also smaller and have a detachable cable, but they may not be as comfortable as the over-ear Focals for long listening sessions. If you often make calls or need active noise cancelling, neither of these options excels in these areas. The KZ ZSN Pro X earbuds are more versatile for on-the-go use and offer good value for money, while the Focal Elex is best suited for audiophiles and at-home use. Give Feedback

"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."
