Type C male to 3.5mm/2.5mm female adapter with a short roughly 9 cm cable. It uses an aluminum housing produced by an oxidation process to deliver good conductivity and durability, with low resistance and clear, detailed sound across three frequency bands. The device employs a dual chip configuration (31988 and 97220) to provide signal to noise ratio and a wide dynamic range. Key benefits Expands compatibility: connect USBC devices to traditional 3.5 mm or 2.5 mm audio accessories such as headphones or microphones, enabling use with cars, PCs, phones, amplifiers, sound cards, and decoding microphones. Reliable signal quality: aluminum construction with low resistance supports clear audio detail and stability. Balanced performance: three frequency balancing helps preserve accurate sound across lows, mids, and highs. Clear listening and recording edges: dual chip architecture enhances signal fidelity with SNR and wide dynamic range.
