【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.
3M 1100 corded type (each pair is individually wrapped in vinyl so they are clean until just before use)
Although the package is written in English, the product is exactly the same as 1110 written in Japanese. (Country of origin: Brazil)
Sound insulation performance (29dB) pursues high soundproofing effect and comfort, and maintains a comfortable fit. While it suppresses noise and background noise, it is still at a level that allows you to hear someone talking to you next to you.
One simple instruction manual will be included with each order. (If you have a desired quantity, please feel free to let us know)
We will distribute a PDF version of the Japanese simple manual to purchasers by email upon request, so please contact us from your Amazon account. I will attach the PDF file to the reply email.
