I'm going through this same decision process right now. I really want to use my own headphones. I'm under no illusion that my earphones (Shure E530) will sound great over BT, but they're comfortable and I like them.
I've been using a Jabra Clipper for a while that I borrowed from a friend, and it just sucks. The range sucks, the sound quality sucks. It's just weak. I've been looking around, and I've found a few alternatives:
I have been unable to find stock on the Sennheister model, and I can't stand the styling on the Street2. For me, so far the BH-221 looks the best of the bunch. It has a tiny OLED display to show incoming caller, it has a built-in FM radio (I don't want this feature, but whatever), the styling is decent, and the clip swivels.
I welcome other people's ideas about these, and any other models you've been able to find. I actually found my way back to this web site because I have some headphones to sell. I lurked for years, and never posted. My post count is 1. So I'll be hanging around posting where I can until I hit 15 and can put my headphones up for sale :) Proceeds from those will pay for my Bluetooth :)
