--------------------------------------------------- 【Voltage Compatibility】 Our products are selected to support international voltage ranges (e.g. 100–240V). However, please make sure your local voltage is compatible before use, as incorrect voltage may still cause 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 appropriate voltage or equipment. --------------------------------------------------- This wearable speaker is easy to wear by simply placing it on your shoulder and does not block your ears, so it puts less strain on your ears even when listening to music for long periods of time. The speaker unit's position and angle have been carefully selected to ensure that sound reaches your ears properly, allowing you to enjoy music clearly even at low volume levels. Since they are wireless, you can move freely anywhere, and since they do not block your ears, you can enjoy music while taking in the sounds of your surroundings. You can also listen to TV audio wirelessly by using the optional Bluetooth transmitter (MM-BTAD5/for TVs). *If you are using a computer without Bluetooth, please see the Bluetooth adapters MM-BTUD45 and MM-BTUD46. The neck part is made of soft silicone for ease of wearing and to reduce strain on the neck.
