Add-on earphones/monitors for ACS & Elacin musicians earmoulds
– ERM-Series™ plug-in earphones
We have developed a unique series of plug-in IEM’s to use with the well known and widely used ER musicians earplugs. As the ER-filters are exchangeable they can now just as easily be replaced with an ERM plug-in monitor so you can use your custom earmoulds for listening to music or for in-ear monitoring on stage.
If you own or plan to buy ER musicians earplugs, this is the easiest and cheapest way to get proper custom earphones!
NEW! ERM-Series now also available in black!
You can choose between several models:
ERM-1 – entry level
ERM-2 – great bass
ERM-3 – compact and musical
ERM-4 – New!
ERM-5 – The Classic
– The ultimate solution for full flexibility
For professional IEM use, the ERM-line can be built together using separate parts. You’ve got your earmoulds and acoustic filters, and can now get your IEM’s too as separate parts – Two earphones and a cord. If one part breaks you can easily replace it. Worried about a cable breakage on tour? Keep a spare in your gig-bag! Perfect for technicians, artists on the road and anyone else in need of a thrustworthy IEM solution 24-7.
