PW Audio 4.4mm Tuning adapter for Astell&Kern A&ultima SP3000 (1960s Silver Ver.)

The PW Audio 4.4F tuning box adopts 2.5mm + 3.5mm (with ground wire), thus possessing extremely high audio filtering and original audio retention characteristics, allowing you to enjoy the original sound. It uses the 1960s Silver internal wiring to make the sound sweeter and more melodious.

Advantage of 4.4mm TRRRS
The positive and negative poles of the left and right channels of the balanced terminal are independent, and the noise interference is low when the signal is transmitted, the sound is cleaner, and the distortion is low. The 4.4mm balanced plug (TRRRS) is divided into five sections, which are the positive pole of the left channel, the negative pole of the left channel, the positive pole of the right channel, the negative pole of the right channel, and a ground pole. When the ground pole is grounded, it is used as a shield. Noise is further reduced, and the sound is more pure, so it has been loved by music enthusiasts in recent years. In addition to having balanced features, the volume is thicker than 2.5mm TRRS, it is not easy to break, the durability is greatly increased, and due to the increased contact surface, it can transmit information more effectively.
