Review: ２つ目のヘルメット用に購入。 高価だけど付け替える手間を考えたら致し方無い。
Review: Perfect for use on a second helmet or replacing a broken / damaged mic or ear pads. Installs and works exactly like the one that comes with the transponder from SENA. Check the reviews on the Helmet you want to install this on to see how much difficulty you'll have mounting it. Some helmet makes are less installation-friendly than others and require you to use the adhesive strips instead of clamping. There should be enough cord to reach the ear and mic mounting areas without issue. Check the instructions OR look for installation tips on SENA's site and from YouTube contributors.
