Features:

USB Data & Power Noise Filter: The Audioquest JitterBug FMJ is designed to remove unwanted noise currents and parasitic resonances from both the data (communication) and Vbus (power) lines of USB ports. JitterBug FMJ meets all USB 2.0 speed specifications. JitterBug FMJ's excellent performance is the result of careful design and craftsmanship, comprehensive technical measurements, and thorough listening tests. As a result the JitterBug FMJ improves dynamic contrast, warmth and resolution of your audio.

Environmental RF Noise Inhibitor: The JitterBug FMJ also thoroughly addresses environmental RF Noise through its full metal case and hinged rubber cover over its USB input. The JitterBug FMJ's full metal jacket helps to shield against RF interference, while the carbon-loaded RF noise-dissipating input-cover helps with the reduction of RF interference when used in parallel.

Dual Discrete Noise-Dissipation Circuits: JitterBug FMJ's dual-circuitry works on both the data (communication) and vbus (power) lines of USB ports. The latter reduces noise and prevents EMI and RFI from contaminating the associated digital-to-analog converter (DAC) and/or cable. The former minimizes parasitic resonances created by the computer and USB bus, and is optimized to remove noise above the USB 2.0 frequency specification, making it ideal for audio playback.

Note: When used with USB 3.0 devices, the JitterBug FMJ purposely decelerates the device to USB 2.0 specifications.

Jitter Reduction: The JitterBug FMJ also measurably reduces jitter and packet errors (in some cases, packet errors are completely eliminated). The result is a clearer and more compelling sound and overall better audio experience.

USB 2.0 Connectors: The JitterBug FMJ features a female USB 2.0 (type-A) port on one end and a male USB 2.0 (type-A) connector on the other end. The JitterBug FMJ draws no power from the source. It will not inhibit your mobile device's ability to charge its battery

Series or Parallel Applications: JitterBug FMJ is extremely easy to use and will offer reliable results for many years to come. It can be used in a series or parallel application. Employ one JitterBug FMJ 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 FMJ in another unoccupied USB port in parallel to the first with second JitterBug FMJ's front door closed.

• Use one JitterBug FMJ in line with any computer and USB DAC (digital-to-analog converter).
• Use JitterBug FMJ with other locally connected USB devices; such as hard drives, printers, and cameras, to effectively reduce audio interference.
• Use JitterBug FMJ with USB-enabled network devices, such as routers, NAS devices, and streamers.
• Use JitterBug FMJ with mobile devices into audio systems in the home and in the car.
• Use an additional JitterBug FMJ in parallel with the first for improved playback performance.
