About External Power Cable EC02 / EC03: ▶ The interference and noise caused by the internal baseband and RF operation of the mobile phone are likely to be transmitted to the USB DAC/AMP through power supply, so the mobile phone is not an ideal power supply for audio Dac&Amp. When using this cable, the current between the phone and the USB Dac/Amp is zero, and the power is directly introduced into the Dac/Amp from the outside power supply without passing through the phone. ▶ Mobile phone output has limitations, especially for Apple devices or some high energy consuming Dac&Amp, using EC02/EC03 can perfectly avoid power supply problems. The phone is only used for data transmission and no longer for power supply tasks.Please click on the image below if you need to purchase separately.

This phenomenon is normal, and it will return to normal after the call/text message ends. ▶ Sometimes there's indeed distortion, disconnection, and other phenomena may occur when connecting Apple products to our PD series dac and some other dacs, mainly due to the output limitation of Apple devices,we suggest you choose our EC02/EC03 cable to slove this problem. ▶ Due to the different types of chips used inside lightning cables, some Lightning to C cables may not be suitable for AkLIAM products. ▶ The bottom of the product is designed with grooves to avoid scratches on the acrylic, and there is a protective film on it,you can remove it when necessary. ▶ Please feel free to contact us if you have any doubt or need help.
