The Prophile 8 is an 8-way balanced armature universal-fit in-ear, made in Germany by InEar. This is an IEM made by pros for pros. It’s a super linear monitoring and mastering tool, so don’t expect a “wow” either in bass or treble when you have the Reference sound version. If you want the truth and nothing but the truth, this is for you! If you prefer a bit more of a fun “V-shaped” sound (more bass and treble), choose the V-shaped sound version or go for the switchable sound version, which allows you to choose the bass and treble of either the Reference sound or the V-shaped model. Whatever version you choose, you will get a super-ergonomic shell design, which sets a new standard as far as fit and comfort are concerned. We don’t know any IEMs that are more comfortable to wear.
