Audible Vibration with Car Kit and Podcasts (BOSE)

[EvilPostIt]

Hi all,

I seem to be getting vibration in my speakers every now and then when using the car phone kit or listening to podcasts... This is seems to be down to something to do with spoken voice but i dont seem to get it when listening to the radio shows when the DJ is talking. Has anyone else had this issue?

Thanks in advance
