Review on FosPower Bluetooth Headphones: Water Resistant Noise Cancelling Sports Earphones with Bluetooth 5.0, Mic, Volume Control - Ideal for Gym, Running, Exercise, Hiking & Outdoor Activities by Troy Larson

First, the sound is pretty good for a pair of inexpensive bluetooth headphones. You'll only notice the noise cancellation when the volume is cranked up to around 80%. I have a feeling it has to do with the fit of the earbuds. I just wish these headphones fit better because they fall out easily. They're fine if you plan on using them while you're studying and not moving too much, but if you're thinking of buying them for work while walking or jogging you might want to look elsewhere. In terms of battery life, it's around 3 hours as advertised, so that's good!
