Anker SoundBuds Life Wireless Lightweight Neckband Headphones. I got a chance to try them and they are absolutely amazing headphones. Battery life is amazing 20 hours. I have been using 1-2 hours for past 4 days and it is still going so I believe it will last 20 hours.
You get multiple ear buds to fit your ear size. Also, it has magnetic ends so they don’t dangle by themselves. I thought wearing this on the neck might look weird but it doesn’t look that bad. It is so light that you don’t even notice it is there.
My only discomfort was when I was stretching/exercising while wearing it and for certain movements, I had to take it off so it doesn’t just fall off my neck. Therefore, I can’t say this is perfect for workout, but it would be perfect for running.
It also has IPX5 rating so you don’t have to worry about this getting some water or some of your sweat.
The button operation was pretty standard and easy to learn if you never used it. Volume up and down, answer calls, etc...
I am not sure how exactly noise cancellation works though. I did hear much less noise from a box fan while I was wearing it but I could still hear some noise from the fan. Other than that, sounds from it was perfect for daily use for regular audience.
