For wireless convenience, it's great. Unfortunately, there are too many shortcomings
First when you take them out of the packaging, it looks very fragile. Couple of major issues with this BT cable. First, they are made with Micro USB and not USB-C. Second, there is no real good way to place the battery/control module; they sort of have to dangle near your neck. Clips they provide are very inconvenient to use as they also dangle off the cable. What they should have done was to have those clips to be able to secure onto the control module. Seems like the design of this cable was an afterthought. As far as pairing goes, if you pair to only one device, it works great. However, you CANNOT remain paired to multiple devices then move the stream from one device to the next one automatically. For example, it does not allow you to connect to your phone and PC at the same time where the audio from say PC to automatically switch to phone when a call comes in.
Lastly, the battery life. At best, you can get couple of hours if you use continuously. If you're thinking of purchasing these, I would do your homework as there are better options out there. Only issue with that is that this is for T2 connector so in order to be able to find the one you like, you may need to use an adaptor such as T2 to MMCX.
In conclusion, sound quality is nice but I think there are better options available at this price point. Hands down, wired option would be best but if you absolutely need the wireless option, consider a dedicated ear buds to those use cases.
