Beat The Buzz

Is your audio still plagued by hum and buzz?

Using multiple plugs within your audio chain means separate earth/ground points. These multiple earth or ground points cause a ground loop problem. This creates an unwanted chain of noise, buzz and distortion.

Struggle no more. the iFi Audio iDefender+ provides the simple, effective solution you need.

Break The Loop

When plugged into the source device’s USB socket, the iDefender+ from iFi Audio detects whether there is a ground loop problem.

It breaks the ground loop by ‘intelligently’ disconnecting the computer’s earth and, as well as eradicating audible ground-loop hum, it lowers the system noise floor, improving resolution and dynamic contrast.

Using a USB DAC?

Are you using the iDefender+ with a DAC that relies on USB power from a computer rather than power from the mains or a built-in battery?

Good news. The iDefender+ offers an additional benefit. If an external power supply is plugged into the USB-C socket on its side, it blocks power from the computer and instead feeds the DAC with ‘clean’ power from the external supply.

If a high-quality, low-noise power adapter such as iFi’s iPower X is used, the performance of the USB DAC will be significantly improved.

New and Improved

iFi Audio has upgraded the circuitry; low-ESR tantalum capacitors have been added for improved input and output filtering. Filtering capacitance has been increased 10-fold.

The iDefender+ now comes in 3 versions and includes the newer USB-C connector.

  • USB-A to USB-A
  • USB-C to USB-A
  • USB-C to USB-C

Beat the buzz with the iDefender+.

Customer Reviews (4.8 / 5 · 5 reviews)

Mia L. ★★★★★

Was tired of that faint ground loop buzz ruining quiet passages in my recordings. This little USB gadget completely killed the noise, and it was truly plug-and-play—no drivers or settings needed.

Joshua G. ★★★★★

Plugged this between my computer and DAC, and the background hum that's been driving me crazy for months is finally gone. It's a simple USB add-on but it isolates the ground loop perfectly.

Ella N. ★★★★★

The hum from my turntable setup was driving me nuts until I put this in the chain. It kills the ground loop between my phono stage and amp completely, and the noise floor is dead silent now.
