What’s Open Ear Sound Tech?
Open Ear Headphone technology refers to headphones that have an open-back design, allowing air to pass through the ear cups to the speaker elements. This design provides a natural and spacious sound experience, but it has its unique characteristics and trade-offs.


Inspired by Road Running
Our Founder Mr Choi is a keen outdoor runner and found that using headphones while running on the road often leads to various dangers. They are not sweatproof, uncomfortable to wear, and cause ear pain after wearing for a long time.

Benefits Of Langsdom Open Ear Headphones

Superior Sound Quality
Open Ear headphones provide a wide and realistic soundstage, making it feel like the music surrounds you. This is ideal for genres such as classical, jazz, or acoustic music, where spatial accuracy is crucial. The open design minimizes internal sound reflections and resonances, resulting in a cleaner, more detailed, and balanced sound.

Comfort During Long Listening Sessions
The open-back structure allows air to flow through the ear cups, preventing heat buildup and reducing sweating, which enhances comfort during extended use. Open-air headphones often use fewer materials for sound isolation, making them lighter and more comfortable to wear.

Reduced Listening Fatigue
The open sound reduces the pressure and "in-your-head" feeling that some closed-back headphones can create, offering a more relaxed listening experience.

Social Awareness
Since these headphones don't isolate you from external sounds completely, you can remain aware of your surroundings, which is beneficial in home or office environments where some level of interaction might be necessary.
