Answers to frequently asked questions

Is the EPOS ADAPT 135T USB II also suitable for video calls across different platforms?

Yes, thanks to the universal wired connection and high-quality microphone, you will easily use the headset for video and audio calls on various platforms such as Teams, Zoom or Skype.

How comfortable is the headset when worn all day?

The headset is designed for office and long-term use, so the cushion and adjustable headband ensure greater comfort even after hours of use.

Does mono sound good enough for listening to music?

Mono headphones like this are not primarily intended for listening to music, but rather for clear communication. For a musical experience, we recommend stereo models.

Is this model suitable for working in a very noisy environment?

The mono design means you'll still hear your surroundings, so in a very loud room, complete isolation isn't possible. If you're looking for more external noise reduction, consider binaural or active noise-canceling models. You can learn more about the differences between models in our headphone guide .

How easy is it to connect the headset to your computer?
