Since the microphone and speaker are integrated into one piece, you can listen and speak with just this one device by plugging it into your smartphone! It's the perfect earphone-type bone conduction microphone for use while driving or in noisy environments.
The "EM21" is an earphone-type bone conduction microphone that utilizes a self-developed bubble-type bone conduction mic. It significantly reduces cable noise caused by rubbing cables, allowing for conversations with just one ear wearing it, making it ideal for situations where you don't want to draw attention to the conversation, such as in security or store operations. The bone conduction microphone detects sound as signals transmitted to the outer ear wall, enabling clear communication even in extremely noisy environments while wearing noise-canceling earmuffs or protective masks that cover the face.
