Key Features

• Long battery life with LED display case: Earbuds provide multiple hours per charge and the smart LED display on the case shows remaining battery for both the case and earbuds.
• Comfortable ergonomic fit: The curved design sits securely in the ear for extended use and comfort throughout the day.

Who It's For

The 21X is best suited for commuters, remote workers, and everyday listeners who want a step up in sound quality and effective noise cancelling without spending on premium-brand models. Its comfortable fit and LED battery display make it convenient for long days and frequent travel.

Those who need audiophile-grade accuracy, studio monitoring, or an aggressive waterproof rating should look elsewhere; the IPX4 rating and consumer-focused tuning are aimed at daily use rather than professional recording or heavy water exposure.
