Now in stock! The 2025 model of Air Pro4! ※Please be aware that inexpensive first-generation Air Pro4s are circulating. Continuous usage time is approximately 2 to 3 hours. ※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. The bass response is very good, and the sound is balanced with an emphasis on bass, resulting in excellent 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 (power saving) Bluetooth frequency: 2.4Ghz Talk time: 3-4 hours Communication distance: up to 12m Charging time: about 1 hour Standby time: 40 hours Waterproof function 【Accessories】 Main unit Charging case USB charging cable Instruction manual ※We will ship in brand new, unopened condition. 【Applicable Devices】 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 will automatically pair just by opening the case lid. 【Touch control function】 Equipped with touch control function on the side of the earphones.
