Thank you for viewing. This is the well-known SHURE SM10A wireless headset. After the announcement of its production completion, I wanted to buy two, so I inquired everywhere and managed to get one. I intended to keep it as a collector's item, so I haven't used it at all after purchasing it. (I opened it for the photos, but I haven't taken the main unit out.) I think this is a rare item that is unlikely to be found in this condition. 【Specifications】 ■ Headset dynamic microphone ■ Cardioid unidirectional ■ Frequency response: 50Hz-15kHz ■ Output impedance: 150Ω ■ Open circuit sensitivity: -65dB re 1V/Pa ■ Connector: XLR3-pin, male ■ Cable length: 1.5m ■ Weight: 78g (excluding cable and connector) ■ Accessories: Windscreen, connector belt clip, carrying case
