Joe 4.0 out of 5 stars Mind you, the sound quality is just fine, but I am not rating it from a perspective of acoustic perfection. I am the person that just wants to be able to get on a plane and watch a movie or sleep without being disturbed. For things like in flight movies, it really does make it easier to hear the movie and improves sound quality. The downside is that some of the jacks on the plane are worn making it hard to get the connection just right (so you get audio to both sides). As for noise cancellation, if you think you can buy anything that will make a baby screaming next to you go away, you should just get earplugs and even that won't totally work. However, it does do a noticeably good job at cancelling out background noise and hushing other annoyances. If I could improve, I would add an extra battery. For some reason mine came with only one battery. I would also buy the over the ears version next time. For long flights they start to hurt my ears even though they are very comfortable for anything under 4 hours. All said, I don't ever fly without them.And never had a issue or problem with them until the padding around the ear portion started to chaff and peel.http://coastalcanineresort.com/images/bose-quietcomfort-3-acoustic-noise-cancelling-headphones-manual.pdf Happened to be at the Mall of America and notice an (BOSE) store and stopped in to inquire about replacement ear pads. The sales person took a look and went on about trying to find out on their web-site if anything was available. With them being old and dis-continued from production. Please keep in mind that she referenced several times how well I had taken care of my head phones. For the newer modal of BOSE noise cancelling series 700. Cover the entire ear. Great sounding tap the right side to answer calls or control the three different levels of noise cancellation. I have nothing bad or derogatory to say about these BOSE products. What I will say or share is this. I know I would not be doing this review. The moral of this review is this. I allowed myself to be indulged to thinking that my QC3 wonderful sounding head phones. Were not worthy of resisting one's soul purpose of replacing them with the newest and better model. Please keep in mind that after all was said and done got back home to Ohio. Started to search out of curiosity for those replacement ear pads for my previously owned QC3 BOSE head phones. Lord and behold found a pair of the exact ones given up. Now I feel complete and comfortable having back what I shouldn't have gotten rid of.I'm the type that will usually get used things of quality to save and this was a good strategy this time. The QC3 are much improved with better bass response than I remember from the QC1s. I was skeptical of the wireless types since conversion to Bluetooth degrades the signal (probably not noticeably since most music is already digital, but that was my thinking). One surprising thing is how long the battery lasts. I haven't timed it but I listen a lot at work and I only have to charge it every few weeks. The built in Mic is great and I can easily take calls on my phone and it goes right back to the music when I hang up.http://thefutureofgolf.eu/wp-content/plugins/formcraft/file-upload/server/content/files/1626c4a2243cae---95-pathfinder-manual-hubs.pdf After hours of listening, my ears will get a little tender, but I have much worse experience with other speakers. Heck, the headset we used at my last job hurt as soon as I put it on. I highly recommend this bargain. Get the tried and true instead of the flashy new. (Ha--I just made that up!)Once I got over the ocean going to Africa, I plugged them in and ONLY THE RIGHT SIDE WORKED. Tried other cords (hard to find because each end is different size!). I'm running all over the Denver, Frankfurt and Cape Town airports trying different cords. Tried this unit in three different players including the airplane's inputs.I was having difficulty hearing books on tape or music from my iPod while flying using regular ear buds - what a world of difference these make. I could still hear voices coming over the aircraft speakers, and some other background noises, but these head phones have such good sound quality, and are so good at masking droning noises, that the background noises I could hear were not bothersome. I've started wearing them around the house (hubby and kids don't like that).:)Cancels general annoying noise, like all airplane background noise the actual plane makes. Generally comfortable for a few hours, but if you wear a very long time they start to ge that around the ears and make you sweat. I suspect most noise canceling headphones are like this however due to the need for a secure connection. I also love BOSE customer support. I have never had an issue with these, but my in-ear BOSE have broken a few times and they replace them no questions asked.Sorry, we failed to record your vote.
