M-Fidelity is a custom in-ear-monitoring and hearing-protection company based in Norway. They were formerly known as “Starkey Norway”, but since their lab’s contract with Starkey has ended they have became “M-Fidelity”. The company has quite a few CIEM offerings in their line, ranging between a large range of prices. Their flagship is called the SA-43 and it has 4 balanced-armature drivers inside of its shells, but there is a twist to that – the user can choose if he wants to turn on the 4th driver in order to change the sound or not. The product of theirs that I am going to write about in this review is called the SA-33. It is very similar to their flagship, and in fact it differs only by not having the 4th BA-driver, meaning that it is actually an SA-43 without the user-controlled sound.
