The AudioQuest JitterBug FMJ is a premium USB noise filter engineered to eliminate RF contamination that degrades audio clarity. Its reinforced metal chassis and carbon-lined output door provide superior electromagnetic shielding compared to the original JitterBug. Deploy it in-line between your source device and USB input, or position a second unit in parallel across an unused port to further reduce noise from the power bus. Ideal for computers, smartphones, streamers, and automotive systems, the FMJ restores the detail and contrast masked by environmental RF interference. Compatible with DragonFly DACs and other USB audio components, this filter reveals the subtlety your music deserves.
