Review on Cancelling Wireless Bluetooth Cancellation Waterproof by Robert Correa

I've been using it for about a week on a single charge for at least 2-4 hours a day and it's still not dead. But other than that it works as stated in the title. Definitely noise cancelling, because even before I turned on the music, the sound around me was definitely reduced, probably by around 80-90%, which is perfect. I'd also recommend checking the volume before turning it on to hear anything because it works, and going deaf isn't an ideal idea (I had an average volume and it was still too loud for me). Also, I wanted more control over the headphones so I got the recommended app and it works better. I prefer to set it to ambient noise as I'm still getting used to noise canceling headphones.
