Microphone Performance

I tested the microphone of the Endorfy Viro Infra Wireless in 2.4 GHz wireless and Bluetooth modes. To review its sound and to compare it to other similar headsets, I used the Adam A7X speakers and Shure SRH840 headphones, both studio monitors, connected to the powerful Topping DX5 II DAC/(pre)amp. The testing was done in Discord and Audacity, and I also used Audacity to record sound from the microphone. The sound was recorded with microphone sensitivity set to 100% and was not post-processed or edited in any way.

For reference, this voice recording was made with the Rode NT-USB, a high-quality studio microphone:



These are the samples recorded in 2.4 GHz wireless mode and in Bluetooth mode.




Here are two samples recorded with the more expensive Viro Wireless for comparison.




Somewhat surprisingly, the Infra's microphone sounds significantly cleaner and clearer than the one supplied with the more expensive Viro Wireless. My voice comes across as natural and intelligible, with much less of the compression typical of wireless headsets, and the capsule's output level is sufficient for voice chat and calls. There's no ENC noise cancellation, though, so background noise such as PC fans or keyboard clatter could be picked up more easily than with the Viro Wireless, if you have ENC enabled on the latter. For a €60 wireless headset, this one has a great microphone.

As with the Viro Wireless, there's no secondary built-in microphone, so the detachable boom microphone is the only one there is. If you want to use the Infra outside the house for Bluetooth calls, you'll have to take the boom microphone with you.
