5. What is the housing material of the FT5? How is the wearing experience?

The FIIO FT5 features a magnesium alloy construction. Thanks to magnesium alloy being only 64% as dense as that of aluminum alloy, the FT5 can be made to be much lighter in weight for long yet comfortable listening sessions.

The FT5 inherits the excellent 3-axis swiveling design used on other FT series of headphones. This allows the earcups to freely rotate and attach to your head no matter the angle or size of your head, for improved quality and better seal.
