Now, the JitterBug FMJ, with its Full Metal Jacket, raises the stakes.
Whether used in series or parallel, the JitterBug dramatically reduces RF contamination generated by a computer, car or other device - the JitterBug FMJ also deals thoroughly with environmental RF noise that takes advantage of the vulnerability of this interface. The metal casing is the most visible change, although even the seemingly innocuous hinged "rubber" piece that covers the JitterBug's output is essential to the JitterBug's improved performance. This little black "door" is RF-tight thanks to a material that is essentially made of RF-absorbing carbon.
Use a JitterBug in series between any computer, smartphone, NAS, streamer, or car radio system and a USB input. For additional sound enhancement, use a second JitterBug in another unoccupied USB port, in parallel with the first, but with the front door of the JitterBug FMJ closed.
