Microphone: Clear, but in Need of Improvement
The built-in microphone is located on the left side of the headset and can be unscrewed. The distance to the mouth can be changed minimally. In the test, the microphone was easy to adjust and delivers a decent performance.
In principle, ambient noises are recorded, but can be filtered out as far as possible by the noise suppression that can be activated in the software. Dull noises are filtered out by a low-cut already without noise suppression.

Voices are recorded absolutely clear and understandable, but don’t sound quite like in nature due to an abruption at approx. 8 kHz. Unfortunately, most headset microphones have this problem. Overall, the recording quality is therefore good, but unfortunately not perfect.
Battery: Comes Loosely over the Day
The battery life is specified by the manufacturer as sixteen hours in dongle mode. In practice, we were not able to achieve this quite high value, but this is also due to the fact that we have fully exploited the headset. The runtime is then about two hours below the specified value. But if you are moderate, you can certainly reach the sixteen hours.
If the headset is operated via a Bluetooth connection, the battery life should be even longer. Sennheiser speaks of twenty hours here. In our estimation, that can actually work.
