Hubby and l have been using Etymotic In Ear headsets for some years now. We just bought the HF3 "in ear" ones, which also double as headsets with our iPhones. Nice feature of these is that Etymotic has released a free iPhone/iPod app called Awareness so that even though they are noise canceling, if the mic detects a certain decibel level it will pause whatever is playing on your device and "let thru" the sound. So when a cabin crew member speaks to you, or the crew do a PA announcement you will hear it with out having to remove the ear buds from your ear. I am quite sure that there is an android version of the awareness app. They are also great for walking/running as if a car comes up behind you, you can hear it.
I have a set of Bose over-ear. They are indeed excellent.
Only downside is the bulky case.
