JitterBug FMJ USB 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 environmental 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.

A JitterBug in series with AudioQuest DragonFlys Black or Red always helps those wonderful creatures fly higher and faster. However it’s best to experiment when putting a JitterBug in front of a DragonFly Cobalt—which itself employs some of JitterBug’s filtering and so the two filters in series can help or hurt performance depending on specific equipment and context.

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.
