An Excellent Neutrally-Tuned 4-Driver Custom IEM

Posted

Pros: Flat tuning with no dips in the frequency response makes this perfect for people who want a neutral sounding CIEM; Clarity is very good.

I still have my 4.A and still enjoy the heck out of it, as a mostly neutral, but slightly forgiving model with very broad appeal. But I gotta say the Noble 4C is probably better for most people. Those who remember how much I enjoyed the 4.A will know how big of a statement this is.   Why? You may recall some complaint about the 4.A having a rather potent "dip" in the response centered around 4kHz. This was measured in the 4.Ai which was the universal model, and I have to say I did hear that fairly...
