Review on Bluetooth Cancelling Waterproof Headphones Microphone by Ryan Hart

These headphones sound very good IF I hold them in the exact right position. As soon as I let go of them, they pop out a little, the bass disappears, the sound becomes tinny and there is outside noise. Maybe I have weird ears. The Revain listing says noise reduction. I don't see anything about it in the tiny manual, and I don't see how to turn it on. Definitely won't work as there is a lot of noise around the headphones. The Bluetooth connection is faulty. My Samsung S8 connected to it normally but while I was walking the signal was glitchy or disappearing every 5-15 seconds. I've found this to happen with the phone in my back pocket - it can't even get the signal from my ass to my ears!? So maybe they're good for listening to podcasts. Not for music, not for my ears. And do nothing active.
