【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. Etymotic High-Fidelity Earplugs are designed to maintain clarity in speech and music by evenly attenuating low, mid, and high frequency bands by up to 20dB. Etymotic High-Fidelity Earplugs utilize resonators and acoustic resistors developed and designed based on years of development experience and accumulated data to reproduce a natural response. They protect your hearing from all kinds of noisy environments, such as live music venues, nightclubs, construction sites, motorsports, and airplanes, reducing the risk of hearing damage. The ear tips are replaceable, so they can accommodate various ear sizes and shapes, allowing for clean and long-term use. [Features of the ER20XS Series] Stemless design for a discreet fit.
