Both cameras I have tried to increase gain (increase the volume) in my quiet room which makes these sound louder than they are.
Other boards:
1. Weaven. Carbon fiber plate, 78g tactile Zealios with GMK keycaps. Foam inside
2. Leopold FC660M. MX Clears on steel plate. Thick PBT keycaps. Bitumen mat inside.
3. Clueboard. Matias Quiet Click on aluminum plate. Thin DCS profile ABS keycaps.
4. Duck Orion TKL. Vintage MX Clears on stainless steel plate. GMK
Quiet to loud (to my ears): Clueboard > Leopold > Orion > Weaven. Still not that loud and I'd say the Orion and the Weaven are really close in sound and not that bad compared to my Déck Legend for example.
It's just that most of my boards tend to be very quiet.
