So I've got Bose X's in the 172 (still building my 9A), and my wife is wanting something lighter and smaller, she saw a picture of my cousin using Halo earbuds and really wants to try those, but they are not available in ANR versions (not surprising, really no place to put the microphone in the earbud). My question is this, for those of you that are using them - are they sufficient without the ANR or am I stuck with the bulkier full-cup design?
