Ah!! To be rich, and throw money away!

Wow!

I have to admit, they look to be a lot better built than the E1's I took apart to repair a few years ago.

Interesting. Here's the folks who make the bass driver, according to the part number in the pics:

Interesting data sheets for part No. CI-2955, for anyone who may be into that sort of thing.

it's from a mainland chinese site. who knows, maybe it's a headphone company out there that took one apart to reverse engineer.

Doesn't look so expensive....but looks aren't the issue here

As an aside, two of those Knowles 2955 (3505S3 though) seem to work in the UE-10 as well, while the high frequency transducer obvouisly is a UE proprietary design. No, I don't had to pull my UE-10s apart - I just have the clear ones.

if these iems use off the shelf transducers then i'd guess that most of their proprietary design went into the design of the cross overs.

Knowles 2955

======
My Digikey catalogue shows these at around $11 each in lots of 100.

heh,
i am just learning these crossover circuits in class today

hopefully i can construct a dual driver headphone myself someday

I wander if I will be able to see the sensa drivers when I get them in?

Most likely the same drivers here....lol
