Product information "ddHifi DJ44 Gold"
4.4mm Female to 3.5mm Male Adapter (Black Gold Edition) 

New Color Scheme – Black & Gold 
In the HiFi era where 4.4mm interfaces have become standard for players and earphones, the 3.5mm jack still retains its irreplaceable charm. The DJ44Gold Black Gold Edition features a solid gold-plated copper grounding shell paired with a black top cover, creating a striking new aesthetic. 

Optimized Compact Design 
The DJ44Gold achieves a 2.1mm height reduction (excluding plug) compared to the DJ44Pro. The redesigned stepless 3.5mm plug design enables an additional 1.9mm reduction, achieving 4mm total height savings for improved portability. 

Premium Material Upgrade 
The DJ44Gold seamlessly adapts 4.4mm balanced earphones to 3.5mm single-ended outputs by repurposing the negative pole as a ground return path, while its gold-plated shell functions as a shielded grounding enclosure, effectively blocking external interference for a more stable audio performance. 

Pentaconn Earphones Socket 
Lower resistance than traditional balanced jacks, reducing signal loss during transmission. 

Nyx-Series Internal Wiring 
High-purity OCC internal wiring with silver-containing solder for purer audio signal transmission.
