You and I have the same guess. But I do think Sony had the deal with them so that they (and Kimber) could read and follow the design and data from Pentaconn. I think the problem with 3rd party is because they don’t know the data of the Pentaconn design parameters

So I totally agree with you, Pentaconn if you can, and Furutech if you must.

Friendly reminder
The 4.4 is a JEIT standard - RC-8141C
Pentaconn is just a brand name, and all parameters are open to anyone.

(but the U sharped female jack seems patented though)

I have a few converter made with Bispa jack and they work extremely well imo.


Honestly, nobody would expect the Bispa plug have the same quality as Pentaconn OFC, but it only cost around 15 USD or so and it is precisly made in Japan, why not?


Upper Bispa , below Pentaconn OFC

Pricey stuff you got there. lol...
Not one but 2 Bispa to Furutech adaptors, one for 2.5mm and the other for 3.5mm. That's $115 a piece.

Trying out my Grado SR325e with my WM1A... very nice so far.
BTW I was looking here in head-fi to get an used WM1A and I ended up founding a new sealed WM1A for around $700 dlls online at a department store in Mexico :ksc75smile:.

Aw man I didn't think I'd have to worry about having a spec made connector. I bought two cables and spent 100 to have balanced connections and really don't want to spend more. Anyone see any obvious issues with these?

Preliminary findings (fully burned by @purk thanks for this again :)) .

They sound better than the Z7, like more clear, that Z7 veil is lifted. Those have bass presence but more controlled, not boomy. Mo crispy and foward mids, Highs seem like that of the Z7 or a bit more, for these i need to listen more and get a definitive review.

Stage is big, damn, like If i was sitting at 1st to 3rd row at a Berliner philharmoniker, wow

edit on stage hmm i am not sure how to define it: as if i was listening to speakers on a big room or like being there live on a concert Hall. CPE Bach Harpsichord concerto H. 415

My cable is actually a sony branded kimber. apologies for the mistake

This happens to me maybe once in a while with Sony kimber cable for z1r but never with EA lionheart cable.. both have 4.4 mm connector. I assume the Sony connector is inferior

Just a matter of two weeks till the Z5 gives up it's position to the IER-Z1R.

Bigger is better with plugs I think. Those look great. Folks who have issues have maybe slightly bent their internal connection parts. That's the thing, bigger plug results more leverage to do damage.

Time to let the slappa case go, it fit the MDR-Z7 fine, but the MDR-Z1R are just too big for it

I use that case with my Z1R and have no problem with the size but it is a very snug fit and the cable has to be removed
