Oh my .. this is not another used iem .. this is ier-z1rBought another (used) IEM to use with my A307 and bloody hell, sounds amazing. My M9's may be in the box a while
... Of course it will be marvelous 
The A300 series has a 4 pole 3.5mm socket for split L/R earth. Means you don't get true balanced but get better L/R channel seperation so maybe less cross-talk and use existing balanced cable.Oh my .. this is not another used iem .. this is ier-z1r
But what is the purpose of that adapter ??
psi , teach me your ways on how to roll IEM cables like that for the life of me I can’t never get my M7 to stay best like you have done for that M9 and Z1R.The A300 series has a 4 pole 3.5mm socket for split L/R earth. Means you don't get true balanced but get better L/R channel seperation so maybe less cross-talk and use existing balanced cable.
This adapter is a 4-pole TRRS 3.5 to 4.4mm.
My twins, using Sony Kimber 4.4mm cable with the Z1R.
Also allows me to keep my IEM's witth 4.4mm cables for my BTR7 and not swapping cables all the time.
here you go, qualcomm qcs2290, 4gb ram, android 12, usb c
Search Z1R holder on youtube for a start. Someone posted a video
Ground separation is there since the ZX2 but has nothing to do with balanced. Its neither true nor false balanced, its just not an balanced connection.The A300 series has a 4 pole 3.5mm socket for split L/R earth.

I already know, some like to refer to it as false/pseudo balanced while its just seperate earth for left &right channel, same as ZX2 when I used it previously.Ground separation is there since the ZX2 but has nothing to do with balanced.

Here is an simplificated explanation from Sony itself. Sadly only in Japanese, but an auto translation should work okayish.
So even though it may be possible to reduce the crosstalk, it doesn't eliminate it because even though the ground is seperated on the plug, it is one device. You only have one walkman, that means the two grounds will, in the end, share the same chassy and so are finally the same ground again. The device has 1 Master ground that all grounds will lead to. And you also don't have any of the other advantages of the balanced connection. You only have 2 LCs instead of 4, and, of course, much lower output power (1/4)
Splitting up the GND is unrelated to a balanced connection and doesn't replace it.
i use it either via aux cable or ive got this Bluetooth receiver that also plugs into the aux that works well. i have an older car tho with no usb in or built-in Bluetooth.
Does anyone know the easiest/best way of importing one of the non capped versions into UK? Amazon Jp won’t ship to UK. Is it accessory jack?
I used zenmarked.jp to import it to Germany. Very reliable.
