Overview

Our take on the AudioQuest JitterBug™

We're big fans of AudioQuest's award-winning DragonFly® plug-in USB DACs (digital-to-analog converters). Now AQ has developed the JitterBug, an innovative device made to enhance the performance of the DragonFly Red v1.0, DragonFly Black v1.5, or any other USB DAC. You simply plug the ultra-compact JitterBug into the USB port of any computer, DAC, receiver, streamer, NAS device, or car stereo to reduce noise and restore your music's clarity, dynamics, and warmth. You can even connect it to your smartphone.

An easy sonic upgrade for your USB DAC

We're big fans of AudioQuest's award-winning DragonFly® plug-in USB DACs (digital-to-analog converters). Now AQ has developed the JitterBug, an innovative device made to enhance the performance of the DragonFly Red v1.0, DragonFly Black v1.5, or any other USB DAC. You simply plug the ultra-compact JitterBug into the USB port of any computer, DAC, receiver, streamer, NAS device, or car stereo to reduce noise and restore your music's clarity, dynamics, and warmth. You can even connect it to your smartphone.

How does it work?

The JitterBug is a dual-function filter that cleans up noise in both the power and data portions of the USB interface. It performs like a line conditioner for the USB voltage bus, as well as acting as a signal filter for the USB data bus. In both cases it suppresses electrical noise that interferes with your DAC's sensitive circuitry. The JitterBug can reduce timing jitter as well, but it doesn't re-clock the digital audio stream to eliminate jitter.

Slightly smaller than the DragonFly, the JitterBug has a male USB plug on one end and a female USB port on the other. If you already own a DragonFly, the JitterBug is an easy, affordable upgrade. Simply plug JitterBug into any of your computer's available USB ports, then plug the DragonFly into JitterBug's USB port. If you're using a different USB DAC, you plug the JitterBug into an available USB port, and use a USB cable to connect the JitterBug to your DAC.

Features

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

Dual Discrete Noise-Dissipation Circuits: JitterBug'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 purposely decelerates the device to USB 2.0 specifications.

Jitter Reduction: The JitterBug 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 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.

Applications: JitterBug is extremely easy to use and will offer reliable results for many years to come. It can be used with external USB digital-to-analog converters (DACs), mobile phones and portable media devices, and network streaming/storage devices. Use the Audioquest JitterBug in the following applications.

  • Use one JitterBug in line with any computer and USB DAC (digital-to-analog converter).
  • Use an additional JitterBug in parallel with the first for improved playback performance.
  • Use JitterBug with other locally connected USB devices; such as hard drives, printers, and cameras, to effectively reduce audio interference.
  • Use JitterBug with USB-enabled network devices, such as routers, NAS devices, and streamers.
  • Use JitterBug with mobile devices into audio systems in the home and in the car.
Note: The JitterBug draws no power from the source. It will not inhibit your mobile device's ability to charge its battery

Optional DragonFly: Audioquest's DragonFly (703DGNFLY2, sold separately) is a digital-audio converter and headphone amplifier with an onboard 64-step analog volume control. It has a USB plug at one end and a 3.5mm minijack at the opposite end. It connects to any Mac or Windows PC and bypasses the computer's compromised audio circuitry to deliver cleaner, clearer, more naturally detailed sound to headphones, powered desktop speakers, or complete audio systems. Insert JitterBug the in series with DragonFly to further reduce noise and resonances.

Why did you buy this?

I chose the AudioQuest jitterbug to act as a filter between my head unit and USB flash drive. AudioQuest quality is outstanding! [ Tom  Oct 09, 2018 ]
My v2 Dragonfly impressed me. Thought I'd see if this might tidy up some of the noise I've noticed in my 5 year old laptop. Whadda ya got to lose for fifty bucks? [ Jon  Jul 11, 2018 ]
I own the dragonfly red. I read the reviews and wanted to see if it would improve my audio on my MacBook Air and iPhone as I also use Audio Quest Night Hawk Carbon headphones. [ richard  Jul 10, 2018 ]
Good reviews about remove noise and improving sound for DAC's using USB connection. [ Keith  Jun 14, 2018 ]
Getting static from laptop in B&W PX + Dragonfly Red that I didn't get with P7. Hope this does the trick. I'll follow up in the comments. [ JORDAN  Jun 13, 2018 ]
looking for additional improvements with computer based music streaming and to complement my Dragonfly black. [ George  May 20, 2018 ]
I own one already, and I want a second unit for my office. It makes sense to galvanically isolate the computer from the external DAC for maximum sound quality. [ Zvi  Apr 12, 2018 ]
I'm always looking for inexpensive ways to improve the quality of my music. I cannot afford high dollar equipment, so this seemed like a good use of my money (based on reviews). [ DAVID  Feb 14, 2018 ]
Hopefully to help my iPhones music sound better through my cars usb [ Joseph  Dec 14, 2017 ]
To go with the Dragonfly black and Grado Rs-2's I recently purchased [ Nicholas  Sep 04, 2017 ]
Very good reviews [ DavidEFLube  Jul 30, 2017 ]
I read some very positive reviews on it on the web. [ Michael  Jun 06, 2017 ]
I have heard good things about the Jitterbug on Head-fi and Reddit when paired with a Schiit Wyrd and Bifrost. So I decided to get it to give it a try with my setup. [ Joseph  Feb 23, 2017 ]
Have not used it recently. Not sure it made a difference in my system [ Larry  Feb 11, 2017 ]
I purchased this Item so that I may use it with my Dragonfly DAC, To Improve Performance./Give It That Little Extra Oomph!!! [ Alejandro  Dec 30, 2016 ]
In an attempt to improve sound quality [ PHILIP  Dec 23, 2016 ]
I have the Dragonfly Red and figured I would try this to see if I am missing out on any more quality from it. [ Bradley  Nov 02, 2016 ]
Like the Dragonfly (on my 3rd - Red), saw lots of good reviews on Jitterbug, so worth a try. [ Keith  Aug 25, 2016 ]
I love JitterBugs, I have a few of them and they really warm up the sound. They're a small investment for a huge payout in sound smoothness... [ Aaron  Jul 06, 2016 ]
noise when streaming from PC [ Joshua  May 12, 2016 ]
To complement the performance of my Dragonfly DAC installed in my laptop ,streaming music to my stereo system. Good reviews noted in several audio magazines. The Dragonfly made a big improvement in sound from my system, I expect the Jitterbug to yield further improvements. [ HOWELL  Jan 24, 2016 ]
Consistently good-to-great reviews as a cheap way to reduce noise in stereo components. [ HOYT  Dec 31, 2015 ]
Read review at Stereophile and thought it might improve my USB DAC sound. POY award winner. [ Brian  Dec 21, 2015 ]
Wanted a product that could minimize any digital packet loss or line noise from the USB output of a MacMini. AudioQuest was the manufacturer for my Dragonfly DAC, so it only made sense to go with the Jitterbug to make sure the DAC was getting the best quality digital signal to convert. Music sounds great both via floor standing speakers and especially headphones. If you prefer the least possible noise & highest sonic quality in your digital music, why don't you have one of these? [ Stephen  Dec 16, 2015 ]
Audio reviews in my magazines. [ ROGER D  Dec 04, 2015 ]

1 question already asked

If your CD player has an USB out that streams and your Integrated amp has an USB input and a builtin DAC for streaming in. First try to connect the CD player to the Integrated amp without the jitterBug before you buy if that works? Then your chances of the Jitter Bug working in line are very good. Note some times some units do not hand shake with the jitter Bug inline, see AudioQuest Forums. [ JAY  Mar 19, 2017 ]
Probably not [ FRED E  Mar 19, 2017 ]
The Jitterbug is placed in a USB pathway; for example: computer USB out > Jitterbug > DAC. The Jitterbug cleans up the USB signal, eliminating jitter. [ DONALD  Mar 19, 2017 ]
No, Not unless the CD player has a USB output, not saying that might not exist somewhere, but that's nothing I've ever seen. I use my Jitterbug in line & in conjunction with a Dragonfly DAC at a USB output from a MacMini personal computer. [ Stephen  Mar 19, 2017 ]
