I used this for few transatlantic flights and they completely removed the engine noise, allowing me to enjoy the in-flight movies. They will not, however, completely remove the sound of a baby crying or a drunk shouting at the flight attendant.

Quality- Over all best product compare to the price. Noise cancellation good but it is less than QC35. Weight or force- Some time it gives little pain on Jaw line near ear. Feature- Battery required, if battery dead headphone still work without but the noise cancellation stop working when the...

Great for cancelling out surrounding noise so you can listen to YOUR music in peace. Comfortable and stay on your head when others may slip off. Great case to protect your investment. Only downside, not Bluetooth.

When it comes to noise cancellation headphones, nobody does it quite like Bose and its the latest QuietComfort 25 headphones are easily at the top of their class. Bose has overhauled the excellent predecessor – the QC15 – and somehow has made it even better with the new QC25.

Good product . But not comfortable for extended wear I bought previous edition on my trip to USA which was very comfortable throughout my flight of 8 hrs flight .

Exquisite Bose quality. Well worth the money. Now I can practice playing my Les Paul into the wee hours of the morning in real gig time!

I bought these headphones for my wife for Christmas. She hasn't tried them yet, but she heard so much about it from a friend of fears. I'm sure she will love them once she uses them.

Typical Bose superior quality product. Build quality very very good, sound quality excellent.

Was angry when I bought these QC headphones then months later a wireless version launched. I bought this device that sits flush with the headphone jack port. It's kight and discreet - if you didn't know the headphones you may not even recognize it's an attachment. Audio via Bluetooth is great.

Seems to work pretty well. I used it on ferry and airplane. it did reduce noise and I could still hear people talking to me. Not a conservation of course. And I could listen to my Ipod which I could not do before>
