SEVIZ Wireless Bluetooth Headphones, 40 Hours, The Best Sound and Powerful bass, Noise canceling, Ear-Friendly earpads, Foldable, Built-in Microphone, Stereo Headphones 11, Black

Good sound, they do block sound more than my other headphones however the "Noise Cancellation" button seems useless. I don't notice any difference in sounds with it on or off. These do help me focus but for anyone wanting this for overestimulation, like woth autism, these may not be good enough for blocking sound.

Need to make them adjust down a little smaller for when you have a shaved head

i love these tbh they do what they are supposed to and for 1/3 of the price :) im happy to say the least

I wished they would sell more of these! They are the best inexpensive set of headphones I've bought on a whim. I ended buying another set, but they quit selling them after that...I would buy 10 more if they were selling again!

Teach online classes with these headphones and they are a life saver. My family was getting annoyed with the level of noise created during my online class and PT sessions.Now only I hear my clients, our conversations are private and I can tune out the noise my family makes in the background which was a headache to me and a distraction to my clients and students.Great buy for the price. Great quality.I'm not sure about battery life, as I habitually charge the headphones during any break between class/ client, but the headphones have lasted 4 1-hour back-to-back sessions, so they are good for at least 4 hours of use at a time.

The headphones connect easily to my cell and the controls are simple to use. I take them to the gym when I work out and since they are inexpensive I don't feel bad about sweating on them. The sound quality is good enough for the price, of course you wouldn't compare them to expensive 'phones. They are comfortable to wear, and I have had them on for almost two hours with no significant problems.The only thing I found lacking was that when running on the treadmill, you can't use the noise-canceling feature as it produces a thump. So you turn it off and crank up the volume a bit, then it doesn't matter. Otherwise the N-C works great and it seems to allow voices and other normal sounds to pass through so you won't be completely isolated.After a few weeks of use I have yet to run out the battery. Just charge them now and then and you are always ready to go.For what they cost, I am quite satisfied with these headphones. Would strongly recommend them to a friend.

Been using it for about a month or 2 now. So personal point of view, it's great for a zone out session but not completely noise canceling. Battery wise it last an average of 4-6 hrs, maybe more on a full charge but I'm not sure I have charged it for that long yet. Overall, great for the price so far.

Noise cancellation really just kind of blurs background you can still here it just goes a little lover it's kind of an irritating feeling like you're under water so I don't use it much. Sounds good keeps in sound pretty well can go almost full blast without much leakage, comfortable too, it also came very nicely packaged was happy bout that, but it doesn't come charged or not for me anyway.

Power button not working after 3 months of usage.
