I am looking for something that is known to play bass lines that extend down to 25 hz audibly and accurately. For example, I used to have 2 Kenwood 12 inch woofers rated to 25hz driven hard and properly by an amp rated down to 20 hz, but they still wouldn't audibly reproduce the lowest note from "I Put On" by Jeezy, which I believe is 28Hz. I am past using loud systems that annoy other people (for now at least), but I want to know if an iem or headphone exists that will deliver in this aspect while maintaining clarity, balance, and decent soundstage?

The deepest bass I've heard is from the Audio Technica ATH-AD2000. It should satisfy your other requirements as well.

If you want to find something a bit cheaper and closed I'd recommend the Ultrasone PRO750.
