Offered here is ONE PIECE(1) BRAND NEW EXCELLENT QUALITY (we call it LUXURIOUS or LUX) aftermarket Remote Speaker Mic that works flawlessly with Motorola Radio Professional series HT750, HT1250 and HT1550 radios. If you currently have an ear mic / earbud for your GP300 series radio, don't throw it away. It will also work with your HT radios via the adapter (included) shown in picture 1 and 2. Simply unplug the speaker mic and plug in your earbud PTT (which we also sell and list separately at eBay). This speaker mic is expensive for good reason!
The adapter's model# shown in picture 1 is 9716.
