Bluetooth headsets for Apple Watch

Hi folks!

So I finally caved in several weeks ago, and I decided to buy the Apple Watch sport, 38 MM.

I got it last night. Initially, the user experience was not very good for me until I restarted the watch after having just started it after the unboxing, which I thought was rather strange, but I digress.

Since I will probably not want my conversations broadcast all over the street as I walk, I thought it would be nice to talk Bluetooth headsets.

What do people use? So far, I considered the <a href="https://jawbone.com/headsets/era&quot; target="_blank">Jawbone Era® Bluetooth® headset</a>
and perhaps the <a href="http://www.bose.com/controller?url=/shop_online/headphones/wireless_headphones/soundlink_oe_headphones/index.jsp&quot; target="_blank">Bose SoundLink® Bluetooth® Headphones</a>
but I can't quite decide.

Both of those I have looked at, and they are obviously in a different price range from one another. the Era seems to have one earbud, whereas the Bose headphones obviously have two. I would feel slightly strange using just one earbud at a time because I'm not really used to it, although I honestly doubt I'd be listening to music very much on the Apple Watch. However, given that I can use them for my iPhone too, perhaps the more expensive headphone options would be better that include two earbuds.

I mostly prefer in-ear and on-ear. There are a lot of variables here, so hopefully I can get some advice based on user experience here.

Thanks!
