Absolutely awesome. No problem connecting, the design looks good and fits over the ears very well, sound quality of excellent. I think the "connected" voice is funny but it happens before you can even get them to your ear so you really have to TRY in order to hear it. Make sure you get the right model to fit your specific buds. I don't plan to go back to other headphones any time soon. Highly recommended.
