Distinguishing between genuine and fake bone conduction headphones is crucial. Genuine bone conduction headphones transmit sound through the vibration of the temporal bone, bypassing the eardrum, which is more comfortable and healthier. Be cautious of counterfeit bone conduction devices that have open speakers on the earpiece. When considering comfort, choose devices that are open-ear, sweatproof, and stable during activities such as running. They should be lightweight and comfortable to wear, allowing unrestricted movement and training. Sound quality is also essential. Select devices with excellent sound production technology to ensure a clear and immersive listening experience. Lastly, consider communication experience. Look for headphones with privacy protection through anti-leakage technology and clear communication through noise reduction technology, which are practical features during phone calls.
