I just did a bunch of overhead/visor and under talent car tests with the 4061,4098 and 4080.
I was surprised.the 4080 sounds pretty mid forward and very present around 1-4khz ,very very little low end under 120hz.it definitely affects voice range.
the cardiod pattern is nice but sonically sounded a bit hard compared to the 4060/4098.
mind you not unusable but to my ears the least favorite.
I still like the 4061's for reasonably close visor mics.w/ an 80hz hpf, sounds very natural.large suv's/trucks or ambient vehicles are a little more challenging reach wise.
these days we almost always wire talent w/ 4061's or 4071's as well .[whispers and last second open windows]
the 4098 [higher self noise/lower output]is still useful when you need a bit more reach and less extreme head turn stuff...or from below.still a bit too directional for head turns imo.placement crucial.
I've seen the trew 4080 gooseneck version in person,my problem is the head assembly[not the actual gooseneck] is still way to long to hide/stash properly up in visors.its about as long as the 4098..over 2".
so the 4080 demo goes back and my quest continues for the ultimate compact/easy to hide,fast and robust sounding car rig.
Ive gotta try the 4011 cardiod cap and active microdot cable to lectro next.
