All,
I know this topic has come up before. Just dont see anything recent. Pretty much everyone who wears wireless Bluetooth buds paired with these watches, and wears the watch on the left hand is aware that there are problems with BT connection loss while exercising outdoors. We've been told to wear the watch on the right arm instead (I find that awkward, and annoying). My remedy with my Bose Soundsports was to just wear them with the wire hanging in front, which helps a lot.
I recently picked up a set of Samsung Buds that are totally in-ear similar to apple ear buds. I ran with them outdoors this past week, and they were totally unusable with the watch on left wrist outdoors. Seems like the BT signal needs to be bumped up a bit?
