Feature. 01

Open Ear Control (OEC)

Why?

Now, you don’t have to take risks and listen to music on the street. Also now, you can communicate with people while listening to music.

What?

OEC allows you to open your ears and listen to ambient sounds. With this features, you can protect yourself from dangers by detecting external sounds.

How?

To make it sound like your ears are open, we analyzed features of microphone and speaker and acoustically tuned them to play the same sound as when the ears are open. Also we optimized quality tuning to minimize sound delay, which the sound played from the speaker is heard later as it’s the sound firstly captured by the microphone.

Feature. 02

Active Noise Canceling (ANC)

Why?

Is it hard to listen to music well because of the loud noise while using bur or subway? Is it hard to sleep because of the loud noise while traveling on trains or airplanes. Is it hard to concentrate because of the loud noise while studying in a cafe? ANC is a feature for these people.

What?

ANC is an excellent feature for using in public transportation such as buses, subways and airplanes or in places like cafes where there are many people. ANC reduces surrounding noise up to 97% (-28dB) and enhance hearing sense to focus on music, study or relax.

How?

Typical earphones simply block ears to reduce noise. However, besides a microphone for phone calls, each side of Sgnl N50 earphone has one microphone on the outside that detect external noise to enable noise canceling. The audio processor analyzes the sound wave that the external microphones collect to produce the opposite sound waves. When these sound waves are heard in your ear together, they offset each other so you can to listen to music comfortably without disturbing by ambient noise.

In comparative testing with other brands, they received very good performance rating in audible frequency band.
