Why the X4A Standout Design Works

• Advanced attenuation features new foam ear cup inserts and spacers that enhance attenuation, paired with upgraded ear cushion foam for a tighter acoustic seal.
• All-day comfort comes from wide, soft foam ear cushions and tilting ear cups that align with your head for a secure fit.
• Extended wearability is supported by an internal stainless steel wire in the headband that maintains consistent force for up to 8 hours, plus a twin headband design to help reduce heat buildup.
