Review on Black Sony WI-1000XM2 Wireless Behind-Neck In-Ear Headset/Headphones with Mic and Alexa Voice Control for Phone Calls - Industry Leading Noise Cancellation by David Elam

Do not buy these headphones, they do not withstand the slightest moisture and heat. Even in wet weather, they don't last long. And when it's hot outside, they lose their Bluetooth connection and you have to reset your headphones to allow them to pair. When I'm a little sweaty, everyone I talk to says I sound very distant or can't hear myself at all until I let them sit in my house for a few hours, after which they start working again. That's probably why Sony dropped the price by $100 to get rid of them. You have to fire the engineer who brought these things to market before they were finished. They have good noise cancellation and I think the sound quality is good. But the headphones keep falling out of my ears and it drives me insane. Sony, you are the best company, you need to think more about your products.
