The Baseus L37 Audio Converter addresses the challenge faced by users of iPhone 7/7 Plus, iPhone 8/8 Plus, and iPhone X, models that transitioned from the 3.5mm Audio port to the single Lightning connection for audio, data, and charging. This adapter provides an effective solution, allowing users to manage multiple functions simultaneously. This adapter converts one Lightning male port into two Lightning female ports, supporting multiple devices. It is designed to handle simultaneous activities such as listening to music, charging the phone, or syncing data, while also supporting hands-free phone calls with Lightning earphones. The compact and elegant design makes it highly portable, easily fitting into a bag without taking up excessive space. Built with a high-quality alloy surface, the L37 features a shiny metal-plated connector that ensures excellent contact, anti-rust properties, and reliable data transmission. The internal design includes a smart processor that facilitates high-quality audio transmission and protects your phone during charging, preventing short circuits or overheating, ensuring safe simultaneous use of audio and charging. Performance-wise, the Baseus L37 supports high-speed charging, capable of supporting up to 2A. It delivers high-quality digital music audio (support 24 bit 48KHz) and is compatible with iOS 10.3 and later, as well as iPhone 7/7 Plus, iPhone 8/8 Plus, and iPhone X, and iPad. Furthermore, it supports data synchronization and charging, making it a comprehensive connectivity tool. While it is a powerful multi-function adapter, users should note its limitations: it cannot be used for connecting two chargers, connecting two sets of earphones, or syncing with two computers.
