I bought these for my wife who was flying to Israel. She loved them. Then I flew across country and borrowed them from her; what a relief they were from the roar of the plane engine. I've never tried the Bose, but these were great and at a fraction of the cost. Highly recommended for any duration of flight.
Of course it's bulky for traveling, but I can't deal with the little in-the-ear phones. This unit is just right for airplane use. It works on the plane's own built-in headphone jacks as well as my iPhone and iPad. It's so quiet when not listening to music that a tap on the shoulder is the only way I can tell that a cabin crew member needs my attention! We also use it at home, with computers and game devices (Nintendo DS and XBox) and even when my grandson wants to watch television and we don't want to hear those annoying, screechy character voices that plague kid's cartoons. Good value for money, and the battery lasts a long time. I'd much rather use an AAA than a rechargeable - I carry spare batteries just in case.
Do not buy these. If you even turn your head or open your mouth the music cuts out. Impossible to use in a car or bus, the slightest movement will cause the sound to cut out. I returned them to the company they said they would check them and replace or repair. Four months later and many phone calls and emails later I finally got them back and they are worse. These headphones are only good for non noise canceling mode, basically I paid a hundred bucks for a 20 dollar set of headphones. Got a 45 dollar set of AblePlanet headphones at Costco and the work great. Will probably buy electronics locally from now on.
