The open ear design headsets enter market around 2014, starting from bone conduction headset, sunglasses, hats, and hearing aid. Air conduction headsets step into market around 2019. 

New users to open-ear headsets may be confused about the difference between bone conduction headset and air conduction headset.  The editor here will brief the differences from five perspectives. 

1. The difference of Sound transmission methods

Bone conduction headset: The sound is transferred via the vibration through your cheekbones, without entering your external auditory canal or eardrum.

Air conduction headset: The sound is transferred via the air vibration.


2. The difference of sound quality

The frequency response curve of bone conduction headset is narrow, projecting unitary sound.


In contrast, the frequency response curve of directional air conduction headset is wide, to better present the high, medium,low sound as well as human voice.


 3. The difference of sound leakage

Under the same test environment: 1meter range, the external sound is captured from the headsets.

The sound leakage of bone conduction headphone is below 50 decibels

The sound leakage of directional air conduction headphone is below 30 decibels.


4. The difference of hearing aid.

The bone conduction headphone transfers sound via vibration through bones, which can help people with hearing impairment to recover.

However, the open-ear directional air conduction headset doesn’t have the same function in hearing aid. It's more used as sports headset, as painless even for long time wear.


5.The difference of water-proof ability.

The bone conduction headphone can reach the ultimate IPX8 waterproof level, just like G8 bone conduction swimming headset.

However, the directional air conduction headphone can reach the level of sweat-proof, but enough for people who don't demand high on the waterproofness, check the AS air3.
