SANWA SUPPLY Waterproof Bluetooth Single Ear Headset FREE MM-BTMH41WBKN

【Voltage Compatibility】 When using electrical appliances, please note that they are designed for Japanese voltage specifications (90-110V), so if you use them with a different voltage, it may cause a malfunction. 【Plug Type】 Our products use Japanese plug types (A or B type). Please use a conversion adapter if necessary. 【Important Note on Transformers and Adapters】 A transformer adjusts voltage to match your device’s requirements. A conversion adapter only changes the plug shape and does not adjust voltage. Using only a conversion adapter without a transformer may result in damage to the product. 【Liability】 We are not responsible for malfunctions or damages caused by improper use, such as operating the product without a transformer. It supports Bluetooth 5.2. This headset features IPX4 water resistance, so you can use it even if you sweat or get caught in a sudden rain shower. These eartips don't block your ears, so you can hear outside sounds and use them safely. This headset features an integrated ear hook that allows you to switch between the right and left ears without having to remove and reattach the ear hooks. The power can be easily turned on and off using the slide switch.
