Yes. I work in pro audio, and have owned two sets Etymotic ER4 in-ear
headphones for nearly ten years. I first bought them to use in my live
recording work, where I'm mixing a jazz band in the same room with the
musicians, and they're often playing pretty loud. The isolation can be
quite good, in the 30 dB range that Bill talks about, but it depends on
how well they fit your ears. The standard fittings are quite soft, and
they happen to fit my ears very well. Every person's ears are different,
and some need custom "ear molds" from an audiologist for the ultimate
isolation.
As I've gradually slowed down my pro audio work, I've ramped up ham
radio and when I got back on the air in 2003, the Etymotics almost
immediately found their way into my ham shack. They're quite
comfortable, and I can wear them for a long time.
The real question is, ":how much isolation do you need?" When I'm
working a SSB contest, I'm very happy with the sound, comfort, and
isolation of the CM500 headset, but I haven't used it yet in a
multi-multi operation. I suspect it will perform pretty well.
