Product information

Description

The Headset EPOS ADAPT 135 USB II is a wired on-ear (supraaural) headset designed for office and call-centre environments. It offers a frequency response of 20–20,000 Hz for clear voice and media reproduction, a 2.317 m cable for flexible movement at the desk, and a lightweight build of approximately 107 g for prolonged wearing. The headset features a single-sided head‑band wearing style in black, a discreet folding boom arm and detachable USB cable with in-line call control, supporting both USB and 3.5 mm jack connectivity for plug-and-play use.

Advantages

This headset combines wired reliability with a compact, foldable design that tucks the boom arm into the headband for a neat appearance when not on calls. Large on-ear leatherette ear pads are designed to improve comfort and provide passive noise damping during extended use. The detachable cable and multiple connector options (3.5 mm jack and USB) make it straightforward to switch between desk phones, computers and mobile devices. An in-line call control and a noise limiter function via EPOS Connect contribute to consistent call quality meeting applicable regional standards.

Suitable for

Office telephony and unified communications
Call centre agents and customer support teams
Hybrid and remote work where clear voice communication is required
Users who need a portable, foldable headset for travel between work locations

How to use

Connect the detachable cable to the headset and to your device using the 3.5 mm jack or the USB connector according to your workstation setup. Position the head‑band so the on‑ear pad rests comfortably over the ear and the boom arm is directed towards the mouth for best voice pickup. Use the in-line call control to answer or end calls and adjust volume as supported by the control. Fold the boom arm into the headband when not in use to maintain a compact profile.

Usage recommendations

For optimal call clarity, ensure the boom arm is placed 1–2 cm from the mouth and aligned with the mouth centre. Use the EPOS Connect software to enable the noise limiter and to check that firmware and audio settings match your communication platform. Store the headset in its carry pouch and fold flat when transporting to protect the ear pads and boom arm.
