AudioQuest JitterBug FMJ USB 2.0 Data & Power Noise Filter

Many tens of thousands of music lovers are already enjoying better audio enabled by the original AudioQuest JitterBug USB Noise Filter—plugged into cars’ USB jacks, laptop computers, USB “service-only” jacks on Ethernet Streamers, and more. Now, JitterBug FMJ, with its Full Metal Jacket raises the stakes. Whether used in series (in-line) or in parallel, JitterBug significantly reduces contamination from RF generated by a computer, car, or other device—JitterBug FMJ also thoroughly addresses everyday RF Noise taking advantage of this vulnerable interface. The new metal case is the most obvious change, though even the seemingly innocuous hinged “rubber” piece covering JitterBug’s output is crucial to JitterBug’s improved performance. That little black “door” is RF-proof thanks to the material being substantially RF-absorbing Carbon. Employ one JitterBug in series between any computer, smartphone, NAS, streamer, or car audio system and a USB input. For an additional sonic improvement, use a second JitterBug in another unoccupied USB port—in parallel to the first—except with JitterBug FMJ’s front door closed. Noise reduction and noise dissipation is AudioQuest! One can’t hear our modern world’s pervasive RF Noise itself, but the compromises it causes robs us of detail and contrast, and outright buries so much subtlety. Fight back with JitterBug FMJ.
