Hi. I know that this post wasn't refreshed for some time but maybe I will be able to help someone.
I was looking for some BT headset with ability to plug my own headphones. If you are looking good quality BT headset you may check some SONY devices. Yeah, I know... Samsung user with SONY headphones. :P I bought Sony SBH50. You may be also interested in two other models SBH20 and SBH52.
