The Sennheisers also support AAC codec for better sound with Apple devices. Choose the KZs for affordability and wired listening, or the Sennheisers for premium wireless features and noise cancellation. 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."

What HiFi? | November 2022
"They are more comfortable and nicer to use than their predecessors, battery life is better and noise-cancelling is now included as part of the package. They’re easy to live with and you could happily listen to them for hours on end without reaching for the pause button. If your budget allows, your ears will be handsomely rewarded."
