Question 1

How well do these reduce noise? Do these active noise cancelling headphones block out airplane noise?

Accepted Answer

No. Despite what the manufacturer, and other (probably paid) reviewers state, there is zero active noise canceling on these headphones. True noise canceling requires an electronic feedback mechanism where soundwaves of a given frequency are opposed by soundwaves of an opposing frequency. These do not have any such electronic mechanism. They are cheap, falsely advertised, and poorly engineered. Not only do they lack any true noise canceling, but--for whatever reason--are practically worthless, because they only achieve a max volume of about 6/10ths of what they should--even when input volume levels are set to the limit.

Question 2

How is the quality of sound in these over ear Bluetooth headphones?

Accepted Answer

Totally. Unacceptable. A waste of money. Cranked at max volume, they are around 1/2 as loud as they should be. I have excellent hearing, and I tried them on multiple devices; same thing, on every single one. Plus, the headset is imply too small for any average adult. I do not have a large head, and they still hurt my ears after 30 minutes.

Question 3

Do these block out people's conversations? I have noisy neighbors

Accepted Answer

Hello, thank you for your inquiry.
The noise cancelling of our headphones mainly focuses on canceling out lower frequency sounds like engines, aviation environment, trains, traffic noise, etc. ANC does not cancel out noises like snoring, talking, music or high-frequency sounds, etc.  But when you listen to music you can have a nice experience with a powerful active noise cancelling function. So, maybe you can focus on what you want to hear more rather than the noise from your neighbors. As our advanced active noise reduction technology quells the noise of airplane cabins, city traffic, or a busy office, makes you focus on what you want to hear, enjoy your music, movies, and videos. 
Hope that helps! Thanks again！
