Summary: Listeners of melodic trance music with these QC15s might fall into a deep stupor... natural highs (w/o substances) might be evoked by the vibrant layers of crisp frequencies that seem to manifest life of their own like fireflies in the dark, dancing in a dimension within and around your head...
Pros: The entitlement of superiority over hipsters sporting Beats... shows you appreciate music more than abiding fashion trends... c'mon, it's Bose!
Cons: Cups get stuffy and humid after 30 minutes of wear... also, you might not realize the fire alarm has went off, or nearby jealous folks talking trash
Summary: I love my QC15s! I have had them for close to 2 years and I don't think I could live without them anymore. They are surprisingly comfortable and light although they get hot if you wear them for a long time.
Pros: Blocks most noise, is surprisingly comfortable, has a great battery life, very sturdy and Boise has a great warranty (when my first pair broke after 3 months they replaced it no questions asked).
Cons: A little bulky to carry around, weird noise if you lay down with them on but the music off.
Summary: These headphones are amazing if you value sound canceling above all else. These are so unbelievably comfortable, and the quiet that you can achieve when flying justifies the price tag right there. My only real gripe is that the sound is not necessarily the best out there.
Pros: Sound canceling is unrivaled, Extremely comfortable, Decent sound
Cons: Better sound can be found for less money, Relies on a battery to function
Summary: I think the headphones work great when traveling. They are comfortable and do a great job cancelling the noise of the engines of a plane or the crying baby sitting next to you. However, if you were to fall asleep and push the headphones against the head rest, there seems to be a low pressure created...
Pros: The headphones are quite comfortable and offer a low and high setting depending on what setting you are in. Also, they cup the ears very well which helps with the noise cancelling abilities.
Cons: Some cons with the headphones are that if you lean to a side and compress the headphone over your ear, it sort of hurts and creates a really loud weird noise. Also the cord is pretty frail and rips near both of the ends. I am already on my second.
Summary: My system had a problem with the audio. It was missing some sound frequencies to my ear when compared to other same model systems. Went many times to customer service and the unit returned the same until they replaced all the boards with a note "just for custumer satisfaction, no problem found".
