Question: Do they cancel the noise of the person next to me talking on cell phone, say on an airplane or bus, while I listen to music?
Document: Well, I used to think my iPod nano(5g) sounded horrible, like a canary singing in a canyon. It was bad enough that I started using my cell phone to listen to music. These headphones have brought a new love for the Nano. The sound quality is great. But it wasn't great straight out of the box. It took around two weeks to really get burned in. So now the sound is perfect with just enough bass and adequate treble.
I read the reviews for these headphones, and it seemed like an amazing product.I had a pair of Beats by Dre, and have used the Sony Noise-Isolating headphones(can't remember the exact headphones). But by far this is the best pair of headphones I have ever used. They are completely what they say. They cancel out any noise. I use them generally for weight lifting, and cardio. I don't hear other people talking or dropping weights.
First I want to say I am not an earbud person...mostly because I struggle to find any that I can wear comfortably. This is the first set of earbuds that I can say I can live with. They do not produce audiophile quality sound however they are very durable, have a ton of different earbud inserts for all size ears and they have a ton of bass. You will know when you have the right fit as they are like earplugs and cancel out almost all outside noise.
I have to say that the bud portion of the ear piece feels absolutely amazing to my ear. Equivalent in feeling to ear buds that cost 5-10 times the price of these.I worked out using these today - elliptical and bike. Then lifted weights. The ear buds never slipped a bit out of my ear.Why not 5 stars? When listening to video or talking on the phone, the sound is very natural. However, when listening to music, there is very little bass.
It doesn't cancel any noise out, because the volume simply is too low. I found myself constantly trying to press them deeper into my ears, so I could enjoy the music. After a few days, I gave up and put them aside.I wouldn't even re-gift this product to a person I disliked or donate them to charity. The experience is like watching a movie with the volume too low to hear the dialogue. Incredibly frustrating!
I use the largest size becuase they give a better seal and better noise isolation. This is the reason why i give them 5 stars, flying via propeller airplane is horrible if your trying to listen to music or watch a movie, this headphones do an amazing job at drowning out airplane noise. The tips will get gunky so you have to clean them out.Case: When i travel i like that i can pack this headphones in their carrying case and not worry about tangling or losing eartips.
I love these and use them for in-ear monitors when playing live music.They stay on my easy and cancel outside noise as well. I even used them to mow once. I was able to listen to audio books on a loud mower.They have multiple fittings that come with the headphones so the fit perfectly.
Having the microphone is handy for those times I forget my Bluetooth headset for my cell phone, but the primary use of these for me will be as headphones to listen to my iPod during workout sessions. Once you take the time to find the proper fit with the rubber tips, they are comfortable (even for people with narrow ear canals!) and with the adjustable wire that hooks over the top of your ear, they remain securely in place while I move around.
My son is very picky and we have had trouble finding a pair he loves.. These are perfect! They have different gel ear buds so you can adjust, they stay in place and cancel noise around you so you can really hear your music or movie. My son takes them everywhere. I also have a pair as well. Can't say enough good things !
I may play around and switch them up to see if these so called "sound-isolating" headphones really isolate the surrounding noises. Today they did not. I guess I am just used to all of the other crummy pairs taking care of that issue.I hope these will last me longer than the others. I run 5 times a week and am training for a marathon. Needless to say, I use earphones more than my cell phone.
Answer: I have used them in a work lunchroom and have completely shut out the noise of the random chatter.  Depending on the level of speaking (which we all know people like to shout in their cell phones) I think they will greatly cut down if not eliminate the noise for you.
