Ahhh Spot, you just made another hole in my pocket...

Thanks :P

If you have ears that wax up a lot (mine do in the spring from allergies) make SURE they send an extra filter kit. You'll get a small kit to change the mesh inserts.
B&H just started carrying these, I think they might have good prices. I've bought mine at tradeshows from Etymotic.

I already have the musicians earplug and I'm scheduled at the doctor each 6 months to get my ears cleared, they get pretty waxy too.

I was thinking about using them in the subway which is quite noisy, with normal earbuds you have to put the volume way too loud which isn't good at all for the ears, I guess this will work out well for this usage ?

:-) You can barely hear muffled screams at low volumes. This is what I love the most about them. One other small caveat, if you use them for shooting vid, it's VERY easy to lose your equilibrium because you're hearing audio from a source other than your natural ears and there is no true sense of spatial relation. I've fallen off curbs and gotten dizzy in large dark spaces when shooting with these. They cut you off from the outside world better than molded in-ear monitors.
Get ready for super sub lows in your head. It's a ball.
For a really trippy experience, get Pink Floyd's "The Dark Side of the Moon" or Dire Straits "Brothers in Arms" and the spaciousness of the mixes take on a whole different meaning. On the DS album, you can hear Mark Knopfler breathing hard at the beginning of a guitar solo in "Walk of Life"

Wow can't wait.
I'll also order the earmold adapters so I can try them with my custom earmolds. I doubt I will use them much with the earmolds because when I use them a lot (several days a week) my canals get irritated because they go really deep and rub against the super-thin skin.

Thanks for the advices, I'll report back when I get them to tell my impression.

I asked a few time ago about these ear plugs and after a trip by plane and work on field now (I'm just back since yesterday by evening).
On the plane, it is simply t - e - r - r - i - f - i - c .
Working on field, ythe only problem is that between the takes, you have to remove them so you can hear the other people on the set, unless you keep your boom mic opened all the time and "hear" with it. I'm eager to try in exteme windy conditions, compared to standard phones which induce some physical/mechanical noise in high winds. I guess under a tuque, these plugs will do miracles too.

Oh, by the way, I didn't go with the Etymotics since it was easier to get the Shure plugs here in Canada (considering the delays i was into). But these comments are surely relevant to the ER-6 too, no?
Oh, a note about the Shures: the cheaper ones are said to have a little more bass than the mid-range model, which is good considering a few people think these mid-range ones **lack** bass... so "one shot, double hit " ...

FuTz, I only tried the Shures briefly, and didn't care for them. Some folks rave about them, others don't. On paper, they aren't nearly as good as the Etymotics, but paper often doesn't tell the entire story.

Oh , yes. And since I noticed the Etymotics have been sold by LocationSound for "at least" 4 years now (first time I noticed those was in their 2001 catalog, it may be more than that), they've probably got more research involved than Shure so they may be one lap ahead. Looks like Shure "followed a potential trend"... (?)
My "experiment" here was to try the thing and if it suits me, buy the best ones later and use these first ones as backups. So I didn't want to invest too much for a first try.
Doing some research on the net, I found a review from a guy who tried both the entry-model and the mid-range model and he preferred... the entry-level model concerning the "sound fidelty". He sais the mid ones lacked bass compared to the entry ones, which had sufficient bass to be used as a reference (ie no obvious "boost").
One guy on this forum who bought the mid-range model also said that he seemed to have to crank up the volume to get sufficient bass from the plugs.
These two commentraies lead me to buy the cheaper ones for obvious reasons... ; )

And one more positive comment for the folks who might want to buy this type of phones for field work : if you're under the sun around noon by 90 degrees or so, GOD is this a relief concerning sweat'n'heat compared to my Sonys big black phones... you simply forget you're wearing phones.

My etymotics are on their way from bh photo :)

would the er4 or er6 be good for mixing & mastering? I have always read/thought to not do a final mix/master with headphones, as the bass response in your head is un-natural compared to what would come out of speakers -
