*Revised - Good Noise Cancelling Headphones for the price
July 9, 2019
*Update: I wanted to update the review on these headphones after normal use. I have used them now for nearly a month for the purpose I acquired them (mowing the lawn) and can now definitively say that they work wonderfully for blocking out sound. I turn on the headphones and enable the ANC and the volume of the riding lawn mower becomes a faint hum. I continuously have to verify that the edge trimmer that I use is still functioning because I can not hear it at all when I'm using these headphones. For noise cancellation they are truly top notch!
I purchased these headphone because I didn't want to wear my $200 pair of NC headphones while mowing and trimming the yard. That said, I was pleasantly surprised at the quality that these headphones provide. I initially had them on and listening to music and was not impressed, but then noticed that there is a separate Advanced Noise Cancelling (ANC) switch to enable that feature and it was night and day difference. You can use the ANC feature w/o Bluetooth enabled or the headphones "on" or you can use the Bluetooth and not have the ANC enabled and get standard sound quality, however, when you do both it is noticeable.
I use these to protect against the sound of using a riding lawn mower as well as when using a weed trimmer. For both of these purposes they work really well. I have had someone come up and talk to my while I had them on and I could not hear them over the music and the ANC enabled. For the cost on these they seem to be a solid set of headphones.
