Review on 🎧 HS-3 Bluetooth Headphones with DSP Audio Algorithm, True Voice Recognition, Rotatable Ear Hook, Graphene Driver, and Fast Charging - Ideal for Workout, Gym, Running and Sports by Brando Carpenter

They were easy to set up and connected almost instantly the moment you turn them on. The sound quality is good. Noise canceling is acceptable. The battery life is about 2.5 hours. That's less than stated, but I don't remember the claim? My biggest problem is that they turn off after about 30 minutes of use. Sometimes for no apparent reason, but sometimes when I crouch. I carry my phone in the front pocket of my pants/shorts. My theory is that when I crouch, my stomach is interfering with the signal?
