⚠️ IMPORTANT COMPATIBILITY WARNING:
This speaker is compatible with the SM-621D Plus 9V transmitter and its matching 9V charging base ONLY. If you own multiple SM-621D Plus sets, do not mix up the charging bases. Do NOT place this 9V speaker on a 5V charging base, as using the wrong-voltage base may permanently damage the speaker.
Replacement speaker only. The transmitter, charging base, and power adapter are NOT included.
Before ordering, please confirm that your existing SM-621D Plus system is the 9V version. You may also power the speaker directly using your original 9V power adapter instead of placing it on the charging base.
