Note: the idefender+ is only a solution for noise generated by having too many grounded devices in your audio chain. Room for more solutions - use an ipower 5v power supply sold separately into the side USB C port for clean DC power on USB powered devices. Not to worry, other 5V power supplies used will benefit from additional noise filtration. Improve sound quality - significantly reduces system noise floor and increases dynamic contrast, warmth and resolution in your music with a measurable difference.

Defend against too many earths - disconnects the USB power from the PC, laptop, or other USB music source to eliminate multiple earths which cause noise interference. If the noise is created by any other source, we’re happy to help discover an alternative. Retains USB 3. 0 high speed data transfer technology for optimal signal transmission.
