Juhall V4.2 Bluetooth Bone Conduction Headphones Review

Juhall V4.2 Bluetooth Bone Conduction Headphones Review

The idea of bone conduction headphones appears to be futuristic, but the concept has been in use for over a century. Famed 18th-century deaf composer Beethoven used this technique to hear his piano notes, via a stick that was connected to his jawbones.

Instead of sending sound vibrations through the air like normal headphones, bone conduction headphones send the vibrations through the human skull, bone labyrinth, and the inner ear, which transmits the signal to your brain’s auditory center via the auditory nerve. 

Bone conduction technology has also been used in hearing aids, sports headphones (especially for runners and cyclists), professional police headphones, call center employees, and in the military. Apart from benefiting those suffering from a Recession Type Hearing Impairment, bone conduction headphones also come in handy when you need to listen to an audio transmission while paying attention to your immediate environment.

Since bone conduction headphones do not occupy your ear canals, they will not block out the sound waves from your surroundings. You can think of them as the opposite of noise-canceling headphones

Despite marketing claims that bone conduction headphones are “safer” in terms of preventing hearing loss, listeners should note that they do not prevent the risk of cochlear damage with prolonged use. Both bone-conducted and air-conducted headphones transmit sound waves that are transduced by the cochlea.

Marketing claims that bone-conduction headphones do not cause eardrum damage are technically true, but their earphone counterparts can also make the same claim if their maximum output level does not exceed 100 decibels (this is the recommended upper limit for MP3 player volumes that has been recommended by the European Union Consumer Affairs Commissioner).
