Newest Earphones in Stock! Air Pro4 2026 Release Model! ※Please be aware that inexpensive first-generation Air Pro4 models are circulating. Continuous usage time: Approximately 2-3 hours OK ※This may vary slightly depending on the Bluetooth environment. Battery life will be shorter if the signal is poor. For charging the charging case, we recommend a fast charger. The included charging cable is just a bonus and will take several hours. Performance is commensurate with the price, so please refrain from purchasing if you are looking for a high-performance product. ※Beware of imitations that claim high performance.
