Haylou PurFree BC01 (SL-BT-HLOU-018)

Bone conduction:Principle: Through the vibration of the transducer, the sound is directly transmitted to the auditory nerve through the bone without passing the ear canal, directly transmitting from the skull to the auditory nerve of the brainAdvantages:Free both ears: no pressure on the ears, reducing the damage to the eardrum Safer: no blockage o... moref the ears when worn, better receiving information around More hygienic: no entry into the ear canal and no dirt, reducing the growth of bacteriaAir conduction:Principle: The sound is transmitted to the auditory nerve through the ear canal and vibrating the eardrumAdvantages:Sound quality: more complete sound information and clearer sound qualityPrivacy: Less leakage of sound from the ear canalSkin-friendly siliconeSkin-like silicone material makes it more comfortable to wear. Resilient front cavity fits more close to the skin and effectively reduces sound leakage.High-sensitivity vibration transducerHigh-sensitivity bone conduction vibration transducer transmits sound directly to the cranial cavity. Specialized vibration reduction technology can suppress sound leakage for full sound details.Qualcomm QCC3044Qualcomm QCC3044 flagship chip, Bluetooth 5.2 chip, two-way communication technology and seamless switch between left and right headphones.
