Ummm a new connector? Like The square one at Fir audio?
Echoing
@rantng's post, it isn't new. It's currently a standard used by the likes of Ultimate Ears and InEarz.
The connectors are not currently easily available, and neither are the FiR RCX connectors. I assume it will take a while (if it all)
JH 7 pin is also not available anywhere I can find yet,
This is exactly what I meant with my post. What I was trying to say was, now that a "bigger" brand like 64 Audio have picked up IPX, it'll hopefully encourage companies like Eidolic, Pentaconn, Oyaide, etc. to come out with higher quantities and more premium builds of the IPX plugs to use with aftermarket cables. And, it'll also encourage newer designs like the right-angled form factor that 64 showed off in their video. The only IPX plugs I've seen thus far from, say, Null Audio have looked pretty basic and bare; definitely unideal for more high-end IEMs and aftermarket cables.
I think this exact problem is what's holding back OEMs from similarly adopting the RCX and the 7-pin standards. They're currently only used by one company with comparatively limited demand for aftermarket cables, so they don't see the need to devote resources for them yet. Once FiR's in-ears become more popular among cable-rolling audiophiles (which I'm confident they will) and JH phases in the 7-pin connector to more of their products (or, better yet, more details are unveiled as to what the 7 pins are for, i.e. their rumoured DSP system), then I'm sure we'll see more adoption of these standards among OEMs and upgrade-cable brands.
UltimateEars and others
are already using the IPX connector and there are several aftermarket cables. However, I have always understood that these connectors spin freely, wear out, and develop “works if it holds right” problems. Yet in 64Audio‘s video, IPX connectors are portrayed as being more robust for musicians who sweat and perform on stage with one monitor out. It’s interesting they acknowledge the 2-Pin connector as being a favorite among audiophiles perhaps only because of the abundance of aftermarket options. For me it’s too early to know which of the two connectors is best—personally I’d pick the one that is less prone to failing in a way that damages the CIEM.
I'm aware that other companies have used it in the past. But, now that a more mainstream (among musicians, anyway) brand like 64 Audio are picking them up, it'll hopefully prompt OEMs like the ones I mentioned above to come out with better-looking, better-made and more comfortably-shaped plugs for the IPX standard. Also, it'll hopefully encourage upgrade-cable makers like Effect Audio or Eletech to adopt it as one of their standard options. I have quite a bit of experience with the IPX standard through my UE LIVE. It definitely does
not spin freely. In fact, that's one of my favourite qualities about it over similar standards like MMCX. After numerous plugs and unplugs, it hasn't loosened one bit. So, I'm definitely for the standard. The only thing it has against it is what we're talking about right now: Limited adoption among brands and OEMs relative to mainstays like 2-pin. Like I said, hopefully, 64's adoption of the standard here will resolve this.
I find it a little strange as they just released the premium silver cable in 2 pons so I assume the new stock premium cable with new connector is the same stock premium cable with new connector simply.
But what if we want new premium silver cable with the new connector? Means you are locked to the stock cable for ever?
A little strange unless they intend to make that option for the premium silver as well.
Personally, I think it makes perfect sense. Keep the premium silver cable on the 2-pin standard, because it's the standard most audiophiles prefer/already have, and they're the demographic most likely to pay for a premium silver cable to maximise their signal chain. And, give the stock cables the IPX standard, because it's preferred for on-stage use, and professionals would care more about durability and water-resistance than minute bottlenecks in the signal chain (as if the mic packs and monitor mixers they're plugging them into aren't big enough bottlenecks to fidelity already). Plus, they're less likely to want to shell out the cash for a premium silver cable anyway.
