JitterBug FMJ (Full Metal Jacket) is easy to use:
Place one JitterBug in-line (in-series) between any
computer, smartphone, NAS, streamer, or car audio
system and a USB input.
For an additional improvement in audio performance,
you can use a second JitterBug in another unoccupied
USB port—that is, in
parallel
to the first.
When using Ethernet, digital coax, Wi-Fi, or Bluetooth
(at home or in a car), plug JitterBug FMJ into an available
USB port to reduce noise.
Note: We always recommend using a JitterBug in-line
(in-series) with DragonFlys Black and Red. However,
because two filters in-series can degrade performance,
