Newest model in stock! Air Pro4 2026 release model! ※Please be aware that inexpensive first-generation Air Pro4s are circulating. Continuous usage time: Approximately 2-3 hours OK ※Slightly varies depending on the Bluetooth environment. Battery drains faster in poor signal conditions. For charging the charging case, we recommend a fast charger. The included Lightning charging cable is just a bonus and takes 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 claiming 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 ※Shipped brand new and unopened. 【Applicable models】 Compatible with various devices with Bluetooth functionality, such as iPhone, Apple Watch, Android smartphones, tablets, iPads, and PCs. 【Auto-pairing function】 After the initial pairing, it automatically pairs by simply opening the case lid. 【Touch control function】 Equipped with touch control function on the side of the earphones.
