If you're on a budget and primarily using earbuds for music and TV in a quiet environment, the KZ ZSN Pro X offers good sound quality and is a strong choice; however, it lacks wireless convenience and active noise cancelling, making it less ideal for noisy environments or exercise. For a premium, the Sony WF1000XM4 provides excellent sound quality, superior noise isolation, active noise cancelling, and useful features like an app equalizer and ear/head detection, which can greatly enhance your listening experience while traveling, during exercise, and in various media consumptions, but its price is also significantly higher. Your final decision should reflect your willingness to pay extra for these additional features or to save money by foregoing them. Give Feedback

Jasper Lastoria | April 2023
"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."
