Review: The Jitter bug works ! - I got the jitters when I thought I needed two of them to sought out the digital jitters & errors in my AV equipments. What the heck you only live once to find out.. So I got two ! And voila it does some kinda magic that makes the music sound impeccable! Sure has stopped my jitters too !
Review: I was skeptical at first, lots of mixed emotions for these, but these absolute make a difference for car audio. It is likely that for home amplifiers these make minimal/not noticeable differences, but for car audio with lower quality components and lower quality amps, especially as vehicles usually have noise/hiss or ground loop issues, this has really helped my setup to sound need factory with an aftermarket android unit for my CLA45 AMG. For anybody else interested, I’m running a 12” Android head unit from AliExpress - had hissing/high pitch interference - i have installed this jitterbug for the Aux to USB converter that is provided to get audio for NTG 5.0 systems, along with a Aux to Aux ground loop isolator and some ferrite filters along the cables - and damn! This setup has made the audio quality near perfect!! (I also tested the same setup without the JitterBug, and you can still hear very minor hissing/high pitch at high volume without this plugged in…. The jitterbug has cleaned this up for me!! Very happy i found this!!

## Questions & Answers

**Q: Is it worth upgrading from the original jitterbug to the fmj?**
A: I certainly wouldn't say you shouldn't upgrade, but if there's a difference in sound quality, it's so subtle that my ears can't detect it.

**Q: I am using df red on my cell phone.  would this improve sound quality of cell phone as a source, or is is mainly for reducing noisier pc sources?**
A: I have the blue and it works great with my cell phone.  Add some high quality noise cancelling headphones and you'll have a high end quality listening experience.

**Q: Can the jitterbug be plugged to my bluray player usb port and improve my listening experience when I watch movies. I have a nice home theater set up.**
A: If your USB on the DVD is a USB standard port then yes it will function. As far as improving your sound, the only thing that this thing does, as far as I know, is filter noise between devices. If your thing that needs improvement is a noise issue then this could help. If you have other issues you are trying to improve then this product is not likely to do anything for you.

**Q: i have a cb radio on my motorcycle and get interferance when transmitting. will this help reduce this noise**
A: i would say no. interference on your cb is most likely from the ignition system on your bike. make sure you have resister sparkplug wires and resister spark plugs.

*by M***Y on 20 June 2024*

I am 60 years old and have been an audiophile for 50. Always trying to improve the sound quality of my audio system. Although I never went crazy and purchased audio equipment in the 10K+ range, I have heard many hours of what expensive audio sounds like. I have found most of it out there is snake oil, but every once in a decade or so, you find a diamond worth it’s value. The JitterBug FMJ is a diamond, not snake oil. It really works. I’d actually pay 10x its value for what it does. It improved the sound of my digital music 25%-50%, along with an AudioQuest (Cinnamon) USB cable, a computer/music server, a DAC with a Saber chip and a Vac-Tube Amp. I have yet to compare headphone sound quality. Everything musical has: more stereo separation, clarity and imaging detail along all frequencies more realistic and open sounding (out of the speaker box sound) a little more soundstage (surrounding sound outside the speaker edges) most all Music Genres sounds more balanced and open Musical Instruments will have: more analog sounding realism, while still retaining its digital sharpness less digital jitter and muddiness (its most noticeable feature) string vibration- can be heard more (guitar, piano) percussion- is clearer and stands out more voices- have more authentic raspiness and realism Synthesized Waveforms- you will hear more- wobble during smooth wavy sequences graininess during distorted sequences You will also get Black as Pitch quite parts, with zero background noise. Your music collection will sound noticeably different…better.
