5S+ Music/Headphone Feedback Thread

Since I noticed the other similar headphone thread seemed to be skewing toward feedback on recommendations for the 5+, I thought I would start a thread centered on the 5S+ since the smaller watch may have its own unique issues with bluetooth connections.

If anyone wants to provide feedback on their attempts at using music on the 5S+ with headphones, I think it would be helpful to have the following information:
1) Have you tested your headphones indoors only, or outdoors too? (Bluetooth connections may not work as well outdoors.)
2) Did you test while walking only? While running?
3) Did you test with GPS on? (If so, which types?)
4) Did you test with the watch on your left wrist? Right wrist? Or both?
5) And most importantly, did your headphones work well with the 5S+ and would you recommended using them?

I would NOT recommend.

Two tests thus far: outdoor running with the watch on both the left and right wrists. GPS + Galileo on. (I plan to test again outdoors with week and will update if results materially differ from the below.)

Test 1: a 3.5 mile outdoor run on the left wrist. Music almost immediately began cutting out as I started my run (although it seemed to be working OK during my warm-up walking). A good connection was never re-established and I had to eventually turn the headphones off because it was so unlistenable.

Test 2: a 4 mile outdoor run on the right wrist. I was more hopeful this run would yield positive results since the headphone bluetooth receiver is on the right side. The connection stayed pretty solid with some intermittent skipping through about 2.5 to 3 miles. However, with about 1 to 1.5 miles left, the connection kept skipping just as badly as during test 1 when the watch was on my left wrist. I again had to eventually turn the headphones off because it was so bad.

Suffice to say, I'm pretty disappointed. I'm willing to purchase a pair of headphones that will work well with this watch, but with how delicate the bluetooth connection is, I'm afraid to order some and have them also not work well after testing.
