No - I have the uncapped version.

I have the uncapped zx100, and purchased the matching nc earphones. The noise cancelling is adequate, but I rarely use the earphones, since the sound quality out of them is average. Unless you work in a noisy environment, I wouldn't bother with them.

FYI, I tried the shirt clip from my Ety ER4xr's. Perfect fit. You can get them for $5.00 if you're interested. http://www.etymotic.com/consumer/accessories/er4-new/er38-55-4sx.html

Please let us know.

Agree on syncr. I've been using it for years. Works beautifully.

I have. The bluetooth cable. Also. Try cinching it up against the back of your head. Seems to work for me.

Comply makes some tips for it, which I tried. They stay in my ear ok, but significantly degrade the sound unfortunately.

Agreed. Ergonomics are a pain tho.

Thanks for the clarification ! Amazon it is then. :)

Apparently Etymotic will issue a credit of around $100 if you trade in your HF3 on a new er4xr/sr. Anyone have any experience doing this?

Yes, I got some last week. They stay on the drivers and in my ear ok. Sound is a little degraded in my opinion.

I purchased mine for a good price from Sonic Electronix. They're an authorized dealer.

I ordered some, I guess we will see. I'm thinking positive.

Comply is making foam tips for the ie800 now. http://www.complyfoam.com/products/sen-isolation/

Westone makes a Bluetooth cable with mmcx connectors if that interests you.
