If you highly value active noise cancelling for quieter environments and wireless convenience with added features such as a microphone for calls, an integrated app with equalizer, head detection, and longer battery life, the JBL Live 670NC headphones would be suitable, especially during air travel or in noisy settings. However, keep in mind that their overall sound quality is considered poor. On the other hand, if you're on a budget and prioritize better sound quality, with the ability to change cables for balanced audio, and don't need wireless functionality or noise cancellation, the KZ ZSN Pro X earbuds are a good choice, but they lack features for exercises like sweatproof certification and have a poor mic quality for calls.

"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."
