Fosi Audio continues to be a rising force in the budget hi-fi market. While best known for its affordable desktop amplifiers, the brand has recently expanded into more traditional hi-fi.
In the last several months, for example, Fosi Audio has introduced its first over-ear headphones, i5 ($550), as well as its first turntable, the Luna3 ($349). And now it is continuing the trend with the IM4, its first pair of in-ear monitors.

Fosi Audio’s IM4s are in-ear monitors aimed at burgeoning audiophiles. They have an open-back design that, similar to open-back headphones, promises to deliver a natural sound with a wider soundstage compared to most (closed-back) in-ear monitors.
And, because of their open-back design, these IM4 in-ear monitors are intended for use in quiet spaces — not only will outside sounds interfere with your music, but others will also be able to hear what you’re listening to.
