Earcup Rotation 

• Each earcup is rotatable 90 degrees 
• Rotate earcups slowly and carefully
• Resistance will arise with rotation in the wrong direction or outside of a 90-degree capability
• Immediately stop rotating when resistance arises
• Ignoring arising resistance and forcibly rotating earcup in a wrong direction or beyond 90-degree capability may result in hinge damage

Earpad Replacement

• When replacing earpads, be aware of earcup rotation resistance 
• Whenever possible, keep earcups in a 45-degree position during earpad replacement 

Elastic Rubber Band Packaging

• The elastic rubber band in the traveling EVA case is tight, which means users may have to push headphone earcup to pack or unpack headphones
• To avoid hinge damage, remove the rubber band by cutting it off at both ends
