The LSs are not bulletproof but their customer support is outstanding.
The passive NR is poor but so are most ANRs. I carry an old pair of
DCs just in case something goes wrong with the LS that a fresh battery
won't fix on the spot. The 30-3g has outstanding stereo sound for
music usage, plus automatic mute when a radio transmission goes either
in or out.

I doubt that in-ear types provide good ANR even if they exist. Heavy
ear canal usage can also produce irritation and ear infections, though
you can probably prevent the latter by changing foam pads often and
making sure they are always clean before use. Also, you wouldn't want
to use in-ear types for passengers because of possible infection
transmission.
