Question about Logitech M705 Marathon

I would consider it rather quiet.
The up and down bottoms do not make any noise.
But clicking, scroll wheel and that other button right below the scroll wheel do make noise. It is not loud to my ears.

I would say the mouse click is quite loud compared with others

Its standard mouse not quite mark "silent mouse"

Silent like all optical mice, but with the tiny feedback clicks from the buttons - you can't avoid them if you want tactile feedback from a device.

mouse is not chatty, but yes, it clicks
