If you're getting frequent disconnects, my guess is that either you are near a source of bad interference, such as a power line, or one or both the devices have an old bluetooth chip that doesn't support newer versions of the spec. The improvement in bluetooth over the past decade has been surprising and admirable. Not that it's perfect now, but for many use cases, it is pretty good. Only your use case will decide whether you can, or would want to, use only wireless audio devices.
