With the launch of the Austru, Cypher Labs have developed their first hybrid IEM with a triple BA design in keeping with the C6IEM but with an additional 10mm dynamic driver underpinning the low end of the Austru’s performance.
The Austru filter switch is positioned at the crossover point of the dynamic driver. This selector switch is designed to deliver either a 50% roll-off or 50% increase in low-end performance of the Austru depending on how you view the default setting of the switch. The BA design is divided into 1 for the mids and two for the high-end response.
As with the C6IEM, the Austru is also a 3D printed shell (in keeping with the original process of the C6IEM development) which to my knowledge only a handful of boutique manufacturers are deploying this technique right now in making IEMs and mostly in the CIEM sector such as 64Audio and Own Phones.
The nozzle design is quite short actually compared to the likes of Noble and Campfire Audio and is terminated in an aluminum filter at the tip. A lot of the fitting issues are likely to be determined by the width and length of the tip you use for the Austru which will give you the “last mile” in term so insert depth and comfort.
Sitting in between the nozzle and bass port on the side of the acrylic shell is the bass filter switch which is discreetly color in black to blend in with the shell. It has an average resistance to the finger so it is possible to knock it forward or backward accidentally but only with a bit of focus in that area from your fingers. Otherwise, it is in an accessible location and not too fiddly to get access to on the go.
The shell connectors are a traditional 2-pin recessed connection which makes the Austru very accessible indeed for aftermarket cables. The cable itself is more or less the same as the original C6IEM cable in looks though this time the memory wire is is color coordinated in black and slightly softer than the
