Klein Curl Wired PTT Headset for XP3

The CURL Wired PTT Headset rests on the ear for comfortable, all-day use. The CURL headset may be worn on the right or left ear by simply rotating the earpiece.

Klein custom designed the CURL headset to reliably connect to Sonim’s SecureAudio 3.5mm Connector on the XP3 handset. This allows the CURL headset connector to twist into place into the handset. The CURL headset has a large, easy to access PTT button, compatible with heavy work gloves.
