Hi , You good people,

MR4 IEM from Paiaudio, COMING SOON:)
Quad bA drivers IEM ( it's a single low, dual mid, single high crossover configuration).
These are the pictures of MR4's demo units.

They look kind of look like MR3, you can only see one driver through the transparent housing lid while you can see two if it's mr3.
