These are ear cuff type, open-ear earphones that clip onto the ear. They don't block your ears, so you can hear the surrounding sounds. Recommended for home use and work indoors, so you won't miss family voices or the intercom! They achieve a sound similar to bone conduction while using air conduction. In my subjective opinion, the sound quality is not bad for the price. The comfort of earphones that don't go in your ear is addictive! #AirConduction #BoneConduction #OpenEar #WirelessEarphones #BluetoothEarphones
