Product details:

● Use original TPA3116, NE5532With Bluetooth 4.2

● The precision SMT resistor is used to ensure a good signal-to-noise ratio of the whole machine.

● The PCB adopts 1.6mm thick double-sided sheet, 2.0 oz copper thickness, and the whole process of tin-spraying ensures the good passing performance of the current. First-class PCB quality.

● With fully enclosed dust-proof potentiometer, the performance is more stable and more durable than ordinary potentiometers!

● The red-grey ring audio special high-current inductor is used to ensure the sound is crisp and powerful.

● It adopts full aluminum chassis, and all the surface of the chassis is processed by wire drawing oxidation coloring process!

● Bluetooth is connected in the same way as a normal device.
