Summary: I purchased this for my wife's birthday. Of course I had to verify the quiet factor. I installed the battery, nestled my ears into a comfortable position and flipped the switch. All T.V. sound terminated. I'd like to tell you I listened to my favorite tunes, but I didn't. I have tennites (ringing in the ears-like a million crickets). The sound deadening, however, lives up to all expectations.
Cons: Should contain a lithium ion battery that you can recharge like your cell phone. I can't believe these babies cost $300.00 bucks and you have to replace a stupid battery every 4 to 8 hrs.
Summary: My first pair of Bose noise cancellation headphones have indeed delivered their promise of fantastic sound. The noise cancellation feature is the best i've experienced. Compared to the beats cancellation the Bose's are vastly superior. when you switch them on you clearly tell that sound from the outside is being reduced but not completely gone.Though i will say depending on what is making the sound you wont hear it and this is without music going.
Pros: Very light for the size Battery life is quite long Inline mic with controls for IOS fully functioning
Cons: The jack wire is too long would've liked if the travel case was hard plastic inline mic controls not fully functioning for android 4.4
Excerpt: These are wonderful headphones. Very comfortable and block out so much unwanted noise. I use them while riding the subway to and from work every day. I can actually hear my music over all the train noise! I would definitely recommend them to friends.
Summary: I prefer the sound from my Beats Studio headphones, but the noise cancelling on the Bose is outstanding. I use them when mowing and doing other loud yard work. I tried several other brands hoping I could get a deal and still good noise canceling. After several failures, I caved and bought the Bose.
Pros: Noise cancelling with good sound.
Cons: Sound (IMO) not as good as Beats Studio headphones. Construction feels fragile vs. other brands.
