LID, or Linear Impedance Design, enables a consistent, reliable sound regardless of what you're plugged into. All of our current in-ear monitors feature LID except the A18t, U18t, and Fourté™ models.
LID is a proprietary circuit that corrects the non-linear impedances of the drivers, restoring proper interaction with the source and preserving the desired sound signature.
PLUG INTO ANY SOURCE
Smartphones, body packs, amps, and DAPs produce audio with different output impedances. The interaction of the earphone impedance curve with the sources may result in the same IEM sounding different with different sources. LID mitigates these inconsistencies, so you can enjoy the same sound across sources.
