BOSE QC15Nothing else.
ive had the qc3's and the qc15's and i think theyre pretty much the same noise cancelling wise
QC15 has more passive noise cancellation than QC3 (although it may have less active noise cancellation, which makes them balance out) and are more comfortable (due to less active noise cancellation and their surround-the-ear design as opposed to on-the-ear design) IMHO.
some people think that on ear is more comfortable. to each his own
I'd say the two things which stand out about them are, for ear buds, they've got to be of the most comfortable. And I've had them for a year now and they are still like new. I've never had a pair of ear buds last that long without one ear losing sound.
And without headphones its even more comfy, except the noise cancelling is way better on the QC15.
the bose qc15's are $300 on amazon..any way to get a better deal? that's more than a new ipod will set me back...
