*** My update is that Cowin customer service is great. They read this review and asked me questions about my experience. They asked if they could send me another pair to try, and if they were better, would I change my rating. I agreed. I wish I could give them a half star for customer service. The headphones are 3 stars due to the microphone issue. They aren't 4 stars, but the customer service is top notch. I'll give Cowin a shot on other headphones/earbuds when the time arises. They've earned it if they can fix the microphone issues. *** These are good, solid, Bluetooth headphones. The ANC works very well. Battery life is great, and they pair easily. They are a bit heavy and the cups make my ears sweat, but overall they are comfortable. I am giving these three stars instead of four because the microphone is terrible. I was hoping to use these for Skype calls on my laptop, but you sound as if you're in a tunnel. I thought it might be the poor Bluetooth driver for Windows 10, but the sound is exactly the same on my iPhone. The microphone is useless. View these as Bluetooth headphones with ANC. Compare them to others in the price range and make a decision. I listen to music and shows on planes and trains, and they are a good value for that purpose.
