A:AnswerThis is the question I asked before I purchased them and I was told that it was some of the best noise cancellation available extremely disappointed
A:AnswerYes they do work well with an iPod. Just make sure to use the Jabra EQ App to make all of your adjustments and then pair them to your iPod. I always use them with my iPod.
