Summary: I think these are well designed and would buy them again.
Pros: These headphones have the ability to pair with 2 devices at once which is great when I'm in the office. I pair with my music device and my iphone and it automatically detects incoming calls and pauses the music. Once the call ends, the music picks back up. Buttons are well placed. Music quality is very good for bluetooth. Headset is comfortable.
Cons: The music is not as loud as I like, but I suppose that is a good thing on my ears. It's not bad, but if you're a metalhead you may wish they cranked up a little higher.
