Reduce Noise on Data and Power Lines on USB Ports: Use AudioQuest JitterBug FMJ USB Filter on Computers, USB DACs, Streamers, Cars, and Smartphones for Improved Sound
A dual-function USB and data filter that has no peer in the market, the amazingly effective and extraordinarily affordable AudioQuest JitterBug FMJ dramatically reduces the noise and ringing afflicting both the data and power lines on USB ports. Consider the aluminum-bodied JitterBug FMJ the most inexpensive albeit effective computer-audio accessory you can buy.
Simply inserting the versatile JitterBug FMJ into the USB input of any computer, laptop, DAC, receiver, streamer, car, or smartphone significantly minimizes jitter and packet errors, thereby restoring music's warmth, dimensions, depth, resolution, dynamics, clarity, and resolution. A second JitterBug FMJ can also be used in parallel with the first, resulting in even greater improvements. Trust us: You're going to want to have at least one JitterBug FMJ anywhere and everywhere you listen to digital audio. And at this price, you're going to want some to give away to friends.
"[A] smoother treble, deeper soundstage, and more relaxed and natural presentation. A no-brainer recommendation for the asking price."
– The Absolute Sound, 2027 Editors' Choice Award
"I have no hesitation in declaring, loudly and longly, that I can think of no way to spend [$60] that would make me more enjoy my computer-based audio than the AudioQuest Jitterbug."
– John Atkinson, Stereophile, 2026 Recommended Component
"This has to be the coolest accessory I've ever used. Highly recommended."
– Jeff Dorgay, TONEAudio
"More realism: vocals seem less pinched and stressed, you are more able to hear the tubes sagging in a wailing guitar amp in full compression, and the sound of an acoustic guitar no longer has that sort of Ovation-guitar electro-acoustic upper mid 'thunkiness'."
– Alan Sircom, Hi-Fi+
"Time and again I found it made music sound more natural, more believable. It's impossible not to be impressed by the improvement offered by the JitterBug. Where [it] scored time and time again was in the manner in which it appeared to clean up less-than-stellar recordings, removing any fatiguing ‘sizzle' or hash. What a bargain upgrade!"
– John Bamford, HiFi News, Outstanding Product Award
