Designed to Be Heard. Built to Be Seen.
Most IEMs look the same. The OS1 BEA1 doesn't.
The diamond-faceted crystal shell catches light like a gemstone, printed with Opera Factory's signature graffiti artwork. Whether you're commuting, at your desk, or at a listening session - these make a statement before you hit play.
HI-RES AUDIO CERTIFIED
The OS1 BEA1 carries official Hi-Res Audio certification, meaning it reproduces frequencies up to 40kHz - well beyond the 20kHz limit of standard earphones. Pair it with a lossless FLAC library or a dedicated DAP and hear details most earphones simply can't deliver.
10MM GRAPHENE DYNAMIC DRIVER
Graphene is one of the stiffest, lightest materials on earth - and that translates directly to audio performance. The OS1 BEA1's graphene diaphragm moves faster and distorts less than conventional drivers, delivering:
- Deep, textured bass with real sub-bass extension
- Clear midrange that doesn't get lost in the low end
- Controlled highs without harshness
Tuned for modern genres: hip-hop, electronic, pop, R&B.
DETACHABLE CABLE - UPGRADE WHEN YOU'RE READY
The BEA1 edition features a 0.78mm 2-pin detachable cable system. The included 5N oxygen-free copper (OFC) cable delivers clean signal transfer out of the box. When you're ready to upgrade - swap to a balanced cable and pair with a DAC/amp for a significant step up in performance.
This is the feature the original OS1 didn't have. It's why the BEA1 exists.
