Hi: I am looking for the following in a headphone for the iPhone: 1. Great sound quality 2. Over-ear 3. Has microphone so can use it to make calls on my phone. 4. Noise cancellation is good but if the over ear design physically cancels noise pretty well that is o.k. 5. I have a big head so adjustable is good. 6. Being able to fold up and compact is a nice-to-have. I've been searching through Google but haven't seen much that fit this category except for the Monster Dr. Dre headphones and the latest Bose Over-Ear. I might go for the Bose, as I suspect the Dr. Dre headphones are good but overpriced. Any recommendations from people with personal experience with headphones with these characteristics would be great. Thanks!
