Audioquest JitterBug FMJ Full Metal Jacket USB Filter

The AudioQuest JitterBug FMJ is a USB noise filter and improves on the success of the original JitterBug with a full metal jacket for better shielding and an RF-absorbing front cover to reduce interference. It still eliminates unwanted noise travelling through your USB connections but now features enhanced noise dissipation for even cleaner audio. Acting as a passive filter JitterBug FMJ blocks RF and power supply noise before it reaches sensitive audio equipment. You can use it in-series between a USB source and your device or in-parallel in an unused USB port to absorb additional noise. For best results AudioQuest recommends pairing it with DragonFly Black or Red DACs.
