Additional Information

Customer Review Summary

I recently tested the Soundman OKM I Classic Solo D1 microphones as an addition to my Sony 100 D recorder, primarily for field recordings.

These microphones offer an interesting way to capture a stereo image, allowing for hands-free use in busy locations without drawing attention to oneself.

Sound-wise, the OKM I Classic Solo D1s produce a fairly central tone, which can be rectified with a bit of EQ. I was able to record at 96kHz without issues, although the higher frequencies do come off a bit thin.

One downside is the self-noise, which is quite noticeable. If you have access to editing software like iZotope RX, you can manage this, but I wouldn’t recommend these microphones if you lack editing options.

Additionally, the build quality is a concern; the cable feels very thin and fragile, leading to apprehension about accidentally damaging it during use.
