Campfire Audio - Honeydew

Cheap ones: Kbear Rosefinch, Whizzer/Opera Factory OS1 Pro, CCA CRA, More pricey ones: 7Hz Legato, QKZ x HBB Hades, Campfire Audio Honeydew. In case you are looking for a cheap one I would go for the Rosefinch. If you have more money to burn, probably the Honeydew would suffice. :) I only have the Castor Bass and I also had the QKZ x HBB Khan (not the standard QKZ x HBB), but for me the Castor was way better.

I use bass iems with my Meta Quest VR headset which has music games but tinny output on its jack and no EQ. I need big booms for explosions and thundering bass for Beatsaber. If you want cheap, soft, oomph sound the Opera Factory OM1 is a great beginner bass. The 13mm driver might not be the clearest, but there is no replacement for displacement. If you want something more refined that cuts out harsh upper vocals, the Campfire Audio Honeydew is lovely even at higher volumes. The Thor Mjolnir has great bass and attack, but needs EQ to tame its upper range, especially at higher volumes. My ideal unit would have the type of driver from Mjolnir in the size of the OM1 and tuned like the Honeydew.
