DD DdHiFi TC44A Lightning To 4.4mm Adapter

4.4mm Miniaturization Realized through Exquisite Technique

Independent decoding chip

It uses CS43131 for the audio decoding chip, which supports native DSD256 and 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.

4.4mm Single-ended

For 4.4mm earphone cable users, when they want to listen to music on their mobile phone and don’t want to connect too many devices, a simple adapter is the most ideal way at present. The conventional 4.4mm terminated devices are generally large in size, but the TC44A adopts a brand new process structure, so as to make the 4.4mm socket look so small.

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.
