Product information

Description

EPOS ADAPT 135 USB-C II is an on-ear, single-sided wired headset designed for office and call-centre environments as well as hybrid workplaces. It provides USB-C connectivity (adapter/USB-A available), a detachable cable, a discreet fold-away boom arm, and large on-ear foam pads for extended comfort. The headset is lightweight (105 g), has a cable length of 2.312 m and a frequency response of 20–20,000 Hz, making it suitable for clear voice communication and daily professional use.

Advantages

The headset combines business-grade call quality with a stylish, compact design: the boom arm folds into the headband for a neat look when not on calls. Plug-and-play connectivity via USB-C (and USB-A where applicable) ensures straightforward setup across devices. Large supra-aural foam ear pads improve wearing comfort and provide passive noise damping, while the fold-flat ear cup design and included carry pouch make storage and transport simple. An integrated noise limiter switch can be managed with EPOS Connect to meet relevant European and Australian standards.

Suitable for

Office workers and home office use
Call centers and customer support agents
Hybrid workers who move between desk and mobile work
Any professional requiring clear voice calls and a lightweight wired headset

How to use

Connect the detachable USB-C cable to a compatible device or use the USB-A connector where required. Position the headband so the on-ear pad rests comfortably over the ear and adjust the boom arm toward the mouth for optimal microphone placement; fold the boom arm into the headband when not in use. Use in-line call controls to answer or end calls and adjust volume. Install EPOS Connect software if you need to configure the noise limiter or apply firmware updates.

Usage recommendations

For reliable call performance, use the headset with a stable USB port and, if available, the EPOS Connect application to enable or calibrate the noise limiter to regional standards. Store the headset in the carry pouch and fold the ear cup flat to protect the ear pads during transport.

Specifications

Ear coupling: Ear coupling describes the way in which headphones or earphones stay attached to, or inside, the ear. There are three common types of ear coupling: circumaural, supra-aural and intra-aural. Circumaural headphones enclose your ears with large pads that suppress external noise. Supra-aural headphones are typically more lightweight and sit on top of the ears with small pads. Intra-aural headphones come in two basic designs and neither style sits on the head itself. The first are ear buds, which sit just outside of the ear canal, on top of your ear lobes. The second type is actually inserted directly into the ear canal and offers some external noise suppression.: Supraaural
Connectivity technology: The technology that enables connectivity of the device, e.g. wired or wireless.: Wired
Headset type: A headset is headphones combined with a microphone, or one headphone with a microphone. Headsets provide the equivalent functionality of a telephone handset but with hands-free operation. Types of headsets include single earpiece (monaural) and double earpiece.: Monaural
Recommended usage: What the product should be used for, and how it should be used (e.g. ambient temperature).: Office/Call center
Product type: The sub-category of the product.: Headset
Product colour: The colour e.g. red, blue, green, black, white.: Black
Wearing style: The way in which the device is worn.: Head-band

Headphones

Total Harmonic Distortion (THD): Total harmonic distortion is a measure of non-linear harmonic distortion and is given in %. Non-linear harmonic distortions are signals which were not present in the original before the signal was converted by the headphones. These unwanted signals are caused by the diaphragm, whose movements do not precisely move in time with the electric signals that cause it to move. Unfortunately, this is a feature of all electroacoustic transducers. Although it cannot be completely eliminated, suitable steps can be taken to minimise it. However, the user is not interested in why this distortion takes place but in how great the level of distortion must be for it to become perceptible. According to the findings of several research projects, a total harmonic distortion of 1% in the frequency range of 100 to 2000 Hz is imperceptible. Below 100 Hz, the perceptibility threshold lies at 10%.: 55 %
