Born to be natural

Born to be designed to meet powerful function and usability Modeling thinking but become simple and complex Simply do not need to deliberately pursue the curve or shape of the design Complex is every body every key to be repeated to test its interactive, reliability This is the right design

Array microphone

High sensitivity High-end stereo sound quality Enhancing voice quality while inducing environment noises

Craftsman’s spirit

Every detail have been in many trials before it to be determined

Stable and reliable

Continuous recording up to 15 hours 15 years lifetime Full-metal body for better anti-interference capacity
