Description

The EPOS | SENNHEISER ADAPT 135T USB II is a wired, single-sided supra-aural headset designed for office, hybrid and call-centre environments. It delivers a frequency response of 20–20,000 Hz for clear audio, features a discreet folding boom arm and offers plug-and-play connectivity via 3.5 mm jack, USB-A or USB-C.

How to use

Connect the headset to your device using the appropriate connector (3.5 mm jack, USB-A or USB-C). If using a Microsoft Teams-certified variant, use the dedicated Teams button for quick access to the app. Position the boom arm microphone towards your mouth for optimal voice pickup; fold the boom arm into the headband when not in use. Adjust the headband and earpad position for a comfortable fit and allow the leatherette earpads to provide passive noise damping during calls.

Usage recommendations

For best call clarity, keep the microphone boom approximately 1–2 cm from your mouth and avoid covering the microphone with clothing. Use USB-A or USB-C connection for consistent digital audio on compatible systems; the 3.5 mm jack is useful for mobile devices. Store the headset in the carry pouch and fold the ear cups flat to protect the earpads when transporting.
