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. ## Customer Reviews ### ⭐⭐⭐⭐⭐ Produit haute fidélité exceptionnel *by on Reviewed in Canada 5 June 2022* Le AudioQuest JitterBug FMJ est un produit essentiel et exceptionnel pour relier vos appareils électroniques iPhone ipad iPod à votre amplificateur ou à votre lecteur CD.Je l'utilise pour filtrer les jitters de mon iPhone branché à mon Marantz CD6005 via un cable AudioQuest Cinnamon lightning-USB. Le Marantz possède une entrée USB pour profiter de son excellent DAC.Avant de placer le JitterBug entre mon Cinnamon et mon Marantz, le son était excellent grâce encore une fois à l'excellent DAC du Marantz CD6005 et à l'excellent cable AudioQuest Cinnamon.Depuis l'installation du JitterBug, je dois dire que nous sommes dans une autre dimension sonore. Les timbres des différents instruments s'enrichissent substantiellement, la scène sonore se précise davantage étant donné l'impact du filtre JitterBug sur tous les aspects qui concernent la musicalité. Les basses présentent un impact supérieur, les hautes fréquences restent précises et prononcées s'il y a lieu avec moins de tendance à déborder. Bel équilibre sonore et douceur dans un gant de fer solide. Les médiums ne sont pas en reste et s'épanouissent splendidement.Bref ce filtre garde intact la musique et les qualités sonores et musicales de vos appareils en enlevant simplement et efficacement les parasites et jitters qui occasionnaient avant quelques désagréments à l'écoute.Tout sonne plus juste...Courrez vous procurer ce produit si vous utiliser des appareils électroniques pour accéder à votre musique. Pour ma part, je redécouvre en quelque sorte une joie renouvelée à faire du streaming via l'application Tidal.En résumé...Plus de définitionPlus de transparencePlus de solidité et de maîtrise des différents registresPlus de précisionPus de détails font surfacePlus de profondeurTimbres encore plus fidèlesBref plus de musicalité ### ⭐⭐⭐⭐⭐ Excellent to improve aftermarket car audio (Aux to USB converter) CLA45 AMG Android unit *by on Reviewed in Australia 9 February 2024* 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!! ### ⭐⭐⭐⭐⭐ Smooths out any drop in internet connection, so less intrusive noise *by on Reviewed in the United Kingdom 11 January 2022* Used in front of AudioQuest Dragonfly Red.
