Using FiiO LT-LT2 cable you can connect a USB DAC to an Apple device for lossless output up to 192kHz/24bit. Perfect for when connecting products such as the FIIO BTR3K/BTR15/BTR7/Q15/Q7/K9 Pro/K11 to your iOS devices for brilliant results. The LT-LT2 uses high-purity silver-plated monocrystalline wires in 8 strands of 19 cores each for a total of 152 wires. This reduces the resistance of the wires, letting signals travel through the wire more easily and purely – improving high-frequency resolution in your music. Please note: USB devices that consume more than 200mA are not supported. Please do not use this cable to charge Apple devices. Disable USB charging of FiiO devices through the FiiO Control App for best experience. Not compatible with Apple Car Play
