Eliminate Ground Loop Noise

Break the Ground Loop, Enjoy Pure Audio

The iFi iDefender+ is the ultimate solution for eliminating buzz, hum, and distortion caused by ground loops in your audio chain. Plug it into your USB source to detect and intelligently disconnect the ground loop, lowering the noise floor and enhancing audio clarity.

Perfect for USB DACs

If your DAC relies on USB power from a computer, the iDefender+ can block noisy power from the PC and provide clean power through its USB-C port when paired with a high-quality adapter like iFi's iPower X. This dramatically improves the DAC’s performance.

Enhanced Design for Better Performance

With upgraded circuitry, low-ESR tantalum capacitors, and increased filtering capacitance, the iDefender+ significantly reduces noise and improves audio dynamics. Its gold-plated connectors ensure optimal signal transfer for seamless performance.

Flexible Connectivity

The iDefender+ is available in three versions: USB-A to USB-A, USB-C to USB-A, and USB-C to USB-C, making it compatible with a wide range of devices. Its ‘SuperSpeed’ USB 3.0 compatibility ensures fast and reliable audio transfer.

Inject Clean Power

Using the USB-C port, you can inject clean 5V power from an external adapter, disconnecting noisy USB power from the source. Pair it with iFi's iPower X for ultra-low-noise operation.
