Brainwavz, a high-end earphone company owned by GPGS, has used resin 3D printing to make the B400, its latest audiophile-grade earphones. The earphones make use of four balanced armature drivers and a 3D printed housing.

We don’t like to admit it, but it’s undoubtedly true that some businesses have used 3D printing more “for show” than for any real purpose. A few (not all) automotive companies are probably guilty of this approach, which sees an association with additive manufacturing as something of a PR exercise.

That’s why it’s actually quite refreshing when a manufacturer uses 3D printing because they have to, as was the case when earphone company Brainwavz tried—and ultimately failed—to make its new B400 product using liquid injection molds.

It’s not clear exactly what went wrong during the prototype molding, but Brainwavz says the failure ultimately led it toward resin 3D printing, presumably in the form of a Stereolithography (SLA) or Digital Light Processing (DLP) 3D printer.

In the end, 3D printing was used to produce the housing for these cool audiophile earphones, and Brainwavz doesn’t seem to regret a thing.

“3D modeling and printing means we can innovate faster and experiment more, enabling us to create a unique system that lets the the Balanced Armatures perform above and beyond expectations,” Brainwavz says, adding that resin 3D printing allowed the company to fabricate a shape that wasn’t possible with molding.

The Brainwavz B400 uses a four-driver system, with each driver focused on its own specific range of the sound spectrum. Brainwavz says this results in a true audiophile-grade sound. Industry standard MMCX cables are provided, and their detachable nature serves to extend product life span, allow for additional features, and create a “custom product experience.”

The base price for the B400 is $190, and the kit comes with a whole bunch of accessories: 2.5 mm balanced and 3.5 mm stereo MMCX cables with gold-plated plugs, a hard-shell carrying case, a cleaning kit, two sanitary wipes, six sets of silicone ear tips (various sizes), a set of Comply T-100 foam tips, a shirt clip, and a Velcro cable tie.
