PWAudio Ground Resonance– Noise Reduction & Sound Quality Enhancer
PWAudio Sound Resonance connects the 3.5mm ground to the player’s internal ground circuit, creating a common-ground effect that optimizes the return path. This results in a more focused, transparent sound with tighter low-frequency control.
Functionally, it is similar to PW DAP Output Adapters for Astell&Kern and Sony, but in a simplified form—retaining the core grounding benefit without PWAudio’s premium grounding
What is the core working principle?
The core principle behind this PWAudio plug is not simple—it works by connecting the 3.5mm ground (Ground) to the motherboard’s ground circuit, thereby creating a “common ground effect” that effectively influences and optimizes the ground return path. The overall improvement is noticeable: the sound becomes more focused and transparent, and the control of the low frequencies is significantly enhanced.
Usage Tips
Since there may be residual protective oil on the plug from the factory, for better conductivity, it’s recommended to clean the metal contacts with an alcohol wipe first. Insert the plug while the device is powered off, then turn it on and plug in your earphones to listen to music. During regular use, you don’t need to keep unplugging it—just leave it plugged in all the time.
