Based on consumer feedback we have reworked our Master 4 to create the new Master IEM.
We are opening our Trade-Up scheme to all Trinity Sabre, Vyrus, Master 4 and Delta V-II owners.
How this works is simple, you can trade up to the new Master for a ridiculous £60.00 by entering discount code TRADEUPPROGRAM at the checkout. The great thing about our trade-up scheme is that you don't need to return your old iems, you get to keep them!
Production has already started and will start shipping in March 2017.
