Re: QC20 or QC30?
I know this is an older thread...but I'm gonna comment anyway. 😉 I've owned the QC 20's for almost two years. By far, they are the best headphones I've ever owned. Recently, within the last two weeks, I decided to "go big". I bought the QC 35II's. Great sound and wireless. Not the greatest with someone that wears glasses. I took them back to Best Buy and got the QC 30's. Again, the wireless option was very enticing. Overall, very good for the money. Due to the fit of the ear pieces, I think anyone would be hard-pressed to find a better set of in-ear ANC headphones. That being said, IMHO, I feel they are inferior to the wired QC 20's as far as noise cancellation.
