Apple MFi Certified for Guaranteed Performance and Compatbility
The "i" in M15i indicates that it has been certified by Apple's MFi. MFi certification ensures perfect support for iPhone/iPad and seamless integration into the Apple ecosystem. It complies with Apple's stringent requirements for external devices in terms of power consumption and compatibility, avoiding the risk of damage to phones and systems from arbitrary device pairings.
Patented SiP Current Mode Amplifier
The Questyle M18i prioritizes resolving trade-offs between size, power efficiency, and audio performance in portable, battery-powered devices.

Management System
Mobile Mode
In Mobile Mode, the USB audio port is used exclusively for data transmission and does not draw power from the connected mobile device. The M18i operates entirely on its internal battery. Similarly, in Bluetooth Mode, the device relies solely on its battery for power, ensuring no external power source is required.
PC Mode
In PC Mode, the USB audio port serves a dual purpose: transmitting data and supplying power. It charges the M18i’s battery while simultaneously powering the system.
When connected to a USB host device with a current limit, the M18i intelligently manages power distribution. It prioritizes the system’s operation by ensuring stable performance, then dynamically adjusts the battery charging current based on the system’s workload and power availability. This ensures optimal performance without overloading the USB host.
