I have the latest software update for the watch. When using Aukey true wireless earbuds while listening to Spotify music on the watch, after about 5 minutes I get a ”power off” notice in the earphones and they shut off. As far as I can tell, the watch is still playing the music. The headphones are fully charged. This has been consistent behavior. When I pair the Aukey headphones with my iPad there is no problem. They work fine and play as long as I like. Conversely, when I pair a Sony headphone to the Pro Solar watch, they work fine together and do not cut off prematurely. To restate the problem, I get a “power off” notice aurally in the headphones and they shut off with the watch-Aukey combination. Naturally, such a combination is useless when working out. Imam reluctant to buy another headphone set for workouts, if there is an underlying watch problem. The Aukey use Bluetooth 5, A2DP, AVRCP, HFP, HSP, SBC, and AAC.
