MicroUSB to Lightning USB Cable, 10 cm.
This cable can be used with our S2 DAC together with iPhones and iPads.
Apple requires external devices to have a propietare chip in the device or cable, else you will eventually get an error message saying this device is not made for iPhone and is not supported. This cable has the chip and works with iPhones! The cost is quite high because of this added chip, but at last we have found a way to support iPhones.
