I realize I'm new here, but this is something I've experienced first hand... let me know what you think.
I've noticed several threads about issues with mirror mode and 3.5 mm jack issues. NOT REFERRING TO THE HIGH PITCH BLEED OVER ON BIONIC. But a good cable with adequate shielding can help this, it did on mine .To some people a cable or chord is a chord, and the cheaper the better ....... WRONG!!!
I'm a musician, sound is my bread and butter and let me tell you that all cables are not created equally. Typically MOTO and Verizon offer pretty good stuff, with good fitting jacks and plugs on the ends with good shielding. Fit and shielding as well as wire diameter are important.
The difference in a 5.00$ cable off of Amazon and the 25.00cable from moto could be the difference in your phone performing as it should and it running like crap.
If you doubt this, and by chance you play something like the guitar.... and hopefully u have a decent amp.... Hook up your guitar with a cheapo cable and play it, see how thin it sounds. Then go get a cable like a monster or better yet a custom grotes cable. That's who makes mine, 100$ for a 15 ft cable.... now play your guitar ... huge difference.
You could do the same test with the 5$ cable from amazon, vs the more expensive cable from whomever. Its just like using cheap ear buds vs shure ear buds but I personally prefer Altec.
Sorry for the rant but a lot of people are cheating themselves and their phones.
For any of you more tech oriented guys on here, feel free to chime in on impedance levels and such.....
