I'd like to get noise canceling ear phones for upcoming air travel (my first time in 9 years and I have a lot of anxiety issues and think blocking ambient engine noise could help--I have relaxation tapes and music). After looking closely through all of the over the ear models I would go with the audio technica pair (ATH-ANC7), which are $120. The downsides with these that I see is that they do take up more space and I assume they would have the pressure feeling I experienced when trying out the Bose QC line. The benefit is that they look comfortable than ear-canal models and can block sound even when you're not listening to music, and I assume block more noise overall as you're not relying on just the music and physical block to block out noise. But then I started to also consider the idea of in-ear canal earphones. I am writing to ask how good these function as noise-canceling earphones. Is sound blocked out pretty much only when combined with music being on? Would it drown out much of an airplane engine? Also does anyone have experience with the apple in-ear headphones with regard to much sound they block out? Or do you think it's better to go with a line designed for noise canceling, such as some by senheisser designate as travel in-ear canal earphones? I feel like I know more about the over-ear models than in ear-canal, and if I went with over the ear I am pretty sure I would go with audio technica, but I really don't have much clue about in ear canal models. I would like the Apple ones for the price, that they're Apple and are supposed to have good sound quality.But I'm guessing the sound canceling wouldn't be as profound? It would essentially be like having the sound protection of silicone ear plugs while simultaneously blocking out noise with music, I'm guessing? Also does anyone have any experience with anxiety caused by the pressure feeling active noise canceling causes? I experienced no anxiety when I briefly tried in QC 2 and 3 headphones in a store, but I definitely noticed the sensation, but I noticed one reviewer at Amazon said the pressure made him feel "sick." I can be sensitive to things, like fluorescent lights or vibrations,so I am curious if the pressure over the long run would cause dizziness or anything like that. Thanks for any input you have.
