What are open-style Earphones?

• Open-style Earphones are the opposite of in-ear Earphones. They are designed to coexist with ambient sounds rather than block them.

• Open-style Earphones are designed based on natural sound field principle which aims to replicate the auditory experience of the human ear in a natural listening environment. This means users can hear both music and some ambient sounds simultaneously. As a result, they are not ideal for use in extremely noisy environments.

• Open-style Earphones do not have the same limitations on speaker size imposed by the ear canal, allowing for significantly improved sound quality. The speakers are positioned outside the ears, and they use directionalair conduction technology to vibrate the air around the ears and transmit sound to the eardrums.

• By keeping the sound source away from the eardrums, open-style Earphones promote hearing protection and ear health, making them suitable for long-period wear.

• Allow for normal social interaction during use.

• Open-style Earphones can fully reproduce 3D soundscapes, creating an immersive 3D surround sound experience that is distinct from in-ear products.

What are in-ear Earphones?

In-ear Earphones are designed to block environmental sounds by creating a sealed chamber within the ear canal, thus providing noise isolation. However, they come with several significant drawbacks:

• Limitations on Speaker Size: The size of the speakers is restricted by the size of the ear canal, which can impact the potential for further improvement in sound quality.

• Direct Sound Transmission to Eardrum: In-ear headphones deliver sound directly to the eardrum, which can lead to ear canal  inflammation  and hearing loss over prolonged use.

• Inability to Engage in Social Conversations: When wearing in-ear headphones, it can be challenging to have normal social conversations because they block out external sounds.

• Safety Concerns in Outdoor Use: In outdoor settings, in-ear headphones can pose safety risks because they block out external sounds, making it difficult to hear important cues like traffic signals.
  

Does sound leak?

Under normal usage conditions, with the volume set at 60-70%, sound leakage should not be an issue. When the volume is turned up to 80-100%, there may be some sound leakage with certain songs. This is a common issue with all headphones, but it might be slightly more noticeable with open-style headphones. It is the only drawback of the directional air conduction technology that awaits an innovative solution. 

How about the volume?

The volume of NEBULA Series products is designed with EQ curves after thousands of tests by professional sound engineers and is suitable for the vast majority of users. The fixed volume remains constant, so when used in extremely noisy environments, the volume may be perceived slightly lower even though the actual volume does not change.

Why do I feel like the volume is low when others find it fine?

The perception of volume can vary due to differences in individual hearing sensitivity and the inherent volume of different music tracks. Different phone models, operating systems, audio output devices, media players, and audio formats also can lead to noticeable differences in output volume. In such cases, users can balance the output volume by adjusting the output device.
