Seen these posted recently and intrigued me enough to justify a bit of research.
It's 6 Knowles BA per side total 12 (confirmed by seller); I'm gonna ask further for BA models and a FR.
Same one in AVCCK store, not sure if stores are related or product is sourced from a third party.
Any users that can tell about them or pointers to impressions anywhere? Can't find anything about them.
