I use Audio-Technica noise cancelling headphones (ATH-ANC23) with Comply foam tips. Runs on a single AAA battery. I like them because they fit comfortably for me and the AAA battery can easily be replaced. The instructions specifically state not to use rechargeable batteries so that could be a drawback for some. I paid ~$50 a year ago and now it appears they can be found cheaper. Haven't experienced any QC as of yet but the online reviews I read before purchase were mixed.
