250 Ohm Headphone Testing
We tested each device below with a variety of activities. For each activity, you can find the headphone volume setting that we used to get a full volume experience with the Beyerdynamic DT990 Pro 250 ohm headphones.
All devices generally worked well except USB Audio Interfaces. When we tested USB Audio Interfaces, we found that they worked well for music listening, audio editing, and video editing. Still, they didn’t have enough power to monitor a live vocal recording (podcast, voiceover, Youtube Video, etc.). For this purpose, we recommend a headphone amp or the 80-ohm version of these headphones.
