As someone who upgraded from a Samsung S21 FE to a Samsung S24 FE late summer while I still had the Jabra EP10’s, the improvements in range and both staying connected was pretty good. A month later I bought the EP30’s and there was another jump in the streaming connection, especially after the upgrade to Android 16 and One UI 8.0.
You need a Samsung phone with both Bluetooth hardware version 5.3 and Android 16 to maintain a good streaming connection. Anything less will be problematic. You will not be happy with the S21 and it cannot be fixed sine it uses older bluetooth technology.
There are still problems when switching between an transmitter and a stream from your cellphone but they appear to be phone software related. An example is that a notification sound or YouTube stream will pause the Auracast stream and restart automatically when the audio from the phone stops, but a video from X does not interrupt the Auracast stream. Have also found that after repeated Auracast use that the incoming call volume is reduced and can only be reset by restarting the phone.
