That's a nice setup you got there [@]@shure or bust[/@]

Jesusio is my handle.  I currently run a Shure SE846 into a Fiio X7.  I would like an empire ears because from the reviews I gather they are fantastic.

LunaC No, you're right. It's a dual BA. But yes, the x20i is what I have. My mistake.

Also you could probably email Etymotic with the serial numbers from the drivers and they could tell you when it was produced.

@Hutnicks For sure one of my best audio purchases. Absolutely zero regrets and they hold up to new multidriver (Noble 5) and hybrid releases (Klipsch X20i), for me.

I've had a pair for about ten years, and they work just fine.  So probably not.

Those are the (relatively) newer versions.  The old version has the red and blue connectors and a green resistor at the cable tie. 

Got my P1's in from Jet yesterday. They are getting burned in on a balanced cable with my Pono. After an initial listen they seem like ER-4's with an exaggerated bass (in a good way). Excited to see how they sound after burn in. Also, they are retail packaged and perfect. Not worried about the...

I just emailed MEE and asked them. Will post if they reply.

Well I fear the Jet ones may be a grey market batch of bad products. I'll check my serial when they come in. Thanks for the info.

Was it the connectors or the cables? Now I'm concerned.
