２台目のbluetoothヘルメットインカムを買う

嫁と一緒にバイクに乗るためインカム買い増し

鳥取砂丘に行くため、ナビとＢＧＭにでもと買ったヘルメットインカム、スマホが死ななければかなり有用なので阿蘇ツーリングでも大活躍した。もちろんサインハウスのＢ-ＣＯＭやデイトナのインカムと違い、激安中華の中でもさらに激安の￥3500ぐらいのものだ。少し長いがスペックを引用してみる。

接続は２台まで、５００ｍまでは通信できるらしい。購入した当初気づかなかったのだがＦＭラジオもある、試してみたがまぁ聞こえるというレベルで使えないことはない。製造元というかメーカーはsikeoというらしい、アマゾンに出品されている中華インカム群にもなく、aliexpressでも１0セラーぐらいしか取り扱っていいない超マイナーブランドである。
