The ear muffs work great. Have had zero problems with them. Some people have mentioned they had problems with the instructions but it's pretty simple. Plug in a cord and it works without cancelation. Then push the volume button in and hold until you hear a beep to turn on noise cancelation. Also works with Bluetooth.

These are all you could ask for for their price. If youre on the fence, go for it. The noise reduction is on par and the augmented sound is high quality.

Works very well

After a few hours they are not the most comfortable but I feel thats the same with most over ear muffs. They do their job well and you can't beat the price if you catch them here on sale. My only issues thus far is the long term comfort, you can buy gel pads to replace the foam if its really a big issue for you. And they seem to go through the battery power pretty quickly at higher volume, especially if you forget to turn them off.

De muy buena calidad

Functional and comfortable.
