Better sounding, more comfortable TRRS headset!

The Ultra Ergo TW110 was designed exclusively by ThinkWrite Technologies from the ground up with the singular goal of creating a better sounding, more comfortable headset. Informed by professional classroom experience, the Ultra Ergo provides sustained comfort, superior sound, and ThinkWrite’s signature durability.

Featuring ergonomically angled earcups and an optimized audio curve, ears remain protected from the stress of compression and strain of damaging frequencies over longer listening periods.
