Audio interface or DAC for IEMs

[whole quartz]

As someone with the 215, 535, and 846, the audio quality on the 215 is going to be lacking

For the drivers in the unit, you aren’t going to be getting a high fidelity experience. You will get the benefit of the feel and noise canceling. It’s good enough for referencing playback or a click track, not so much if your use case requires the audio to sound… good 😂
