Custom In-ear monitors (CIEM), widely used by musicians and performers. These earphones are custom fitted to the individuals ear for superior isolation and comfort.



It began when I wanted a pair of CIEM, just to realize that the cost for one has well surpassed my budget. So, I wondered if it's possible to make one myself and turns out there's a big community for DIY CIEMs! aka DIEM(DIY- IEM)



This Instructables will document the process of building your own CIEM at a fraction of the price :D
