Description

The EPOS ADAPT 135 USB-C II is an on-ear, single-sided wired headset with USB-C and 3.5 mm jack connectivity, designed for hybrid workplaces and UC professionals. It features a detachable USB cable, a discreet fold-away boom arm for business-grade call quality, and lightweight construction for all-day use. The headset includes large on-ear foam pads, a fold-flat ear cup design and a carry pouch for portability, and an in-line call control with a noise limiter switch compatible with EPOS Connect.

Advantages

The headset combines reliable plug-and-play connectivity via USB-C or USB-A (with appropriate cable), clear audio across a 20–20000 Hz frequency range, and a comfortable supra-aural fit with newly designed foam ear pads that help damp ambient noise.
