I can vouch for how good the CH700N's are, so I can't wait to get my hands on these. They sound like the perfect upgrade for this price point and the inclusion of transparency mode is a welcome surprise. Sony is really pushing the envolope on what is considered a budget pair of ANC Headphones. I just hope they sound as good if not better. Sony seem to know what they are doing working with 30mm drivers now so all things point to yes.
