Inquiry (采购产品): Noise canceling headphones What is the price on this headset? Are they comfortable enough to sleep in? I need them for sleeping. I have a train near me which rolls by every 15 minutes. I also have upstairs neighbors which get ready for work at 2 p.m. They are loud and wake me up. I need soundproof or noise canceling earphones. Are these headphones suitable for my needs? Grateful for any information. Rosalie **** Hidden Message ***** rosalie garibay P.O.
