Product information

Description

The EPOS ADAPT 135T USB-C II is a professional-grade, wired, single-sided headset engineered to meet the rigorous demands of modern hybrid work environments. This headset combines high-quality audio performance with a sleek, minimalist design, making it an ideal tool for office professionals, call center agents, and remote workers who require reliable communication equipment. With its lightweight construction and ergonomic headband, it is built for extended periods of use without compromising on comfort.

Advantages

This headset stands out due to its versatile connectivity options, featuring both a 3.5 mm jack and USB-C compatibility, which allows for seamless plug-and-play integration across various devices. The device is specifically certified for Microsoft Teams and optimized for Unified Communications, ensuring a streamlined user experience with dedicated controls. Its unique design includes a discreet boom arm that can be folded neatly into the headband, transforming the professional office headset into a stylish pair of headphones for personal use. Furthermore, the large on-ear foam earpads provide excellent comfort and passive noise damping, while the fold-flat ear cup design ensures easy storage and portability for professionals on the move.

Suitable for

Office environments and call centers
Remote work and home office setups
Video conferencing and virtual meetings
Professional communication on-the-go

When it may not be suitable

This headset is a single-sided model, which may not be ideal for users who require full stereo immersion or complete isolation from ambient noise in very loud environments. Additionally, as it is a wired device, it may not be the best choice for users who prioritize total wireless freedom and mobility while moving around their workspace.

Key specifications

Wearing style: Head-band
Ear coupling: Supraaural (on-ear)
Connectivity: Wired (3.5 mm jack and USB-C)
Frequency range: 20 - 20000 Hz
Weight: 105 g
Cable length: 2.312 m
Color: Black

How to use

To use the EPOS ADAPT 135T USB-C II, simply connect the headset to your computer, smartphone, or tablet using the integrated USB-C or 3.5 mm connector. The device is plug-and-play, meaning it should be automatically recognized by your operating system as an audio input and output device. For Microsoft Teams users, the dedicated button allows for quick access to meeting controls. Adjust the headband for a secure fit and position the boom arm near your mouth for optimal voice pickup. When not in use, the boom arm can be folded into the headband, and the ear cups can be folded flat for storage in the included carry pouch.

What to consider before purchase

Ensure your primary devices support USB-C or 3.5 mm audio connections.
Consider whether a single-sided headset meets your specific audio isolation requirements.
Verify if your primary communication platform is compatible with the Microsoft Teams optimization features.

Usage recommendations

For the best audio experience and longevity, keep the foam earpads clean and store the headset in the provided carry pouch when traveling. Ensure the cable is not pulled tightly during use to prevent strain on the connectors.

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 %
