Flew an almost 3 hour leg with it today. Unfortunately, it's getting returned and an A20 with Bluetooth will be going in it's place. The sound quality is very good and the noise cancelling is surprisingly good for how it's supposed to work. However, I just can't quite get used to the ear tips. The biggest problem, though, is it squeezes my giant melon uncomfortably. I was developing a headache by the time we landed. The pressure points are just weird on it.
I really wanted to like it.
