An Adapter That Delivers High Fidelity

Independent decoding chip

It uses Realtek ALC5686 for the audio decoding chip, which supports up to 32-bit 384kHz PCM decoding. It can fully decode and play music in lossless format when using Apple Music on iPhone.

Equipped with T-Shaped Lightning OTG plug

ddHiFi developed this new generation of T-Shaped Lightning OTG plug, which has optimized the circuit layout to improve power supply stability, so as to make the output of decoding chip more stable. The plug is made of powder metallurgy and welded with special stainless steel reinforcement.

Ultimate space layout

The design with side socket has many advantages, which can reduce the length of the mobile phone when put into the pocket or backpack, and will not interfere with the palm of the hand when playing games.

Overall CNC aluminum alloy, new color matching

Aluminum alloy is light and has great advantages when used in adapter. The black and blue color matching used this time caters to the popular color of iPhone, and the special treatment process of shell also enhances the metal texture.
