11.Introduction to the optimization effect of structure on sound.

We have placed the drivers in a side-mounted and direct-driving manner in the FH5s, which has made great use of the space and given better consideration to the acoustic requirements to be able to include a 12mm dynamic driver inside the earphone.

The rear cavity utilizes a semi-open design and the tuning hole is hidden in the front cavity. The balanced pressure relief technology applied to the front and rear cavity reduces air pressure on the ear, leading to more comfortable and long listening sessions.

In addition, it inherits the patented cavity design of the FH5 with a 3-point fixation manner to help reduce excess resonance and distortion. The precise 4-way crossover ensures that bass, mids, and treble seamlessly blend without interfering with each other.
