Title: Great for the price
Review: Used these on a 10-hour flight to/from South America. They do not block out all ambient noise, but did make movies and music much clearer and easier to understand. Battery life excellent--never replaced them either direction. Work well just as earphones (switched off) also. Other noise cancelling earphones may work better at blocking noise, but they are several hundred dollars!
