Sorry if im asking the obvious here ....
Have you used Add New Device in the wearable app with the buds in their case open sitting next to your phone or tablet. The wearable app should pick them up immediately
If you have... and this doesn't work, I must ask where you purchased them because fake ones will attach via Bluetooth but not via the wearable app.
There is one sure way of checking them, and that's contacting samsung customer service to check the serial numbers. I've done this myself after purchasing from Amazon before I cut the seal on the box.
