Query: Flaky reception and Uncomfortable

I could not get these headphones to work properly with either of my two Apple computers.I had constant dropouts on my MacBook Air and it disconnected mybluetooth keyboard and mouse on my Mac Mini each time I turned onthe headphones. My WiFi connection became choppy anytime theheadphones were turned on.I worked with Apple tech support and we could not come up with what waswrong. I tried every option I could think of.I found the headset to be VERY uncomfortable. It was hot and was toosmall to fit over my ears, so they "smooshed" my ears and gaveme a headache. The control buttons were so small that I could notreliably use them. Worst ergonomics I've seen in quite awhile.I gladly returned these headphones.
