Edit after long time use: audio streaming is fine for me now. 2 days in a row for 2 hours of music, it works without any problems. I suspect there was some disruption in the early days, although I don't know what was removed from the environment to fix it. Rating stars have been updated to reflect due satisfaction. Customer service contacted me about my first negative review and offered a refund or replacement. I declined both but agreed to try longer tests. First review, removing comments about audio issues: Everything works fine in terms of setup and initial connection. I use bluetooth headphones for a wall mounted candy bar over a treadmill. I added an extension so the adapter is in line of sight with my headphones. Headphones are less than 3 feet from the adapter. I have been using this treadmill for almost 3 years, these headphones are for 1. Previously connected to tablets or phones in the same place as a new computer. This adapter is probably suitable for data synchronization with/with BT device. : Works great for headphones and real-time audio streaming. Initially there were issues with buffering, dropouts and distortion, but I assume it was my environment. Note that if you have audio issues, the adapter may be more prone to interference than a phone or tablet. In this case, turn off other BT devices or move electronic interference (microwave oven, fluorescent lights) between the adapter and your audio device and see if the problem is resolved. The adapter may be more susceptible to interference than a phone or tablet.
