Newest model 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 ※May vary slightly depending on the Bluetooth environment. Battery drain will be faster 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 counterfeit products that claim high performance. The bass resonance is very good, and the balance emphasizes bass, resulting in very good sound quality. ■Product Name: Air Pro 4 Bluetooth 5.0 compatible, touch control compatible, iOS13 compatible ■Condition: Brand new, unopened 【Product Specifications】 Bluetooth version: 5.0+EDR (low power consumption) Bluetooth frequency: 2.4Ghz Talk time: 3-4 hours Communication distance: Up to 12m Charging time: Approximately 1 hour Standby time: 40 hours Waterproof function 【Accessories】 Main unit Charging case USB charging cable Instruction manual ※Will be shipped brand new and unopened. 【Applicable models】 iPhone, Apple Watch, Android smartphones, tablets, iPads, PCs, and various other devices with Bluetooth functionality. 【Auto-pairing function】 After the initial pairing, it will automatically pair just by opening the case lid. 【Touch control function】 Equipped with touch control function on the side of the earphones.
