This enclosure fits the NwAvGuy Objective2 headphone amplifier.

Objective2 was originally designed for a Box Enclosures B2-080BK. In the early 2010s, now-defunct German retailer Head'N'HiFi produced a streamlined enclosure, which was distributed to JDS Labs and Mayflower Electronics. This is the enclosure seen in most O2 pictures 2012-2024.

As of 2025, JDS Labs 3D prints enclosures for its remaining Objective line offerings. This model is perfect for those building the DIY Objective2 headphone amplifier.
