RadiArmor Electromagnetic Wave Prevention Stereo Earphones That Cut Electromagnetic Waves with Air Tube Earphones. 99% Technology. (black)

【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. Summary: Compared to holding a smartphone directly to your ear, it cuts electromagnetic waves by 99.9%. Compared to regular earphones, electromagnetic waves are reduced by 97%. Built-in microphone, volume control, and call response button. Compatible with all smartphones and devices with a 3.5mm earphone jack. Air tube method: Sound is extracted from a speaker approximately 17 cm away from the ear and delivered to the ear through an air tube. There are no conductors or speakers in the earphones that are inserted into your ears, so you can listen and speak safely without electromagnetic waves coming close to your ears. Sound quality: Distortion occurs when passing through the air tube, so the sound quality, especially in the high range, deteriorates. As a countermeasure, it has a built-in high-quality 8mm speaker to complement the sound quality in the high to midrange range. However, please note that the sound quality is not as high as expensive wireless earphones. Features: Volume control and built-in microphone. Compatible with 3.5mm earphone jack. A 3.5mm jack adapter is required for use with iPhone 7 and later, and an Apple genuine Lightning adapter is recommended to use the full functionality of the volume controller. The earmuffs are noise-cutting. If you feel uncomfortable with the earmuffs of noise-cutting earphones, we recommend pod-type earphones. The pod type is available as a separate product. About RadiArmor: RadiArmor develops products that protect the human body from EMF, from pouches to caps. The earphones come with a 1 year warranty. The International Agency for Research on Cancer (IARC, headquartered in Lyon, France), a specialized organization of the World Health Organization (WHO), has announced the results of a study on the relationship between electromagnetic waves from mobile phones and the risk of developing cancer. Therefore, electromagnetic waves from mobile phones have been designated as the third level from the top on a five-level risk assessment, ``2B'' = ``suspected to be carcinogenic to humans.'' Radio Armor earphones protect you from electromagnetic waves emitted by mobile phones and earphones. Our air tube technology blocks up to 99% of the electromagnetic waves from holding your phone directly to your ear and 97% from regular earphones.
