Okay, so couple of clarifying questions for us to try to help. What BT lanyard config did you order from Trinity? The Trinity 2-pin or MMCX? If it's the Trinity 2-pin, it should work with the Sabre.
The Atlas Delta may not even work with this BT cable anyway. I don't remember if there were any updates about if the Atlas Delta is using the new y-split system or not, but my impression is that it will be, which means it's not gonna work with the BT cable you have.
Trinity's 2-pin system uses recessed pins (not recessed sockets, so it's the same style as something like the UE TF10). It also uses 0.75mm pins like the UE TF10. However, on a Trinity 2-pin cable, there's also an extra plastic nub to make sure it only plugs in one way to avoid plugging in the pins the wrong way around.
What's referred to as a "standard 2-pin" is what many manufacturers in the industry use for removable 2-pin cables; this connector uses 0.78mm pins. You will also see these noted as "Westone 2-pin" as well, but that's just another name for the "standard 2-pin". Summary: standard 2-pin is 0.78mm connectors designed for recessed sockets and used on most IEMs with 2-pin removable cables such as Westone/JHAudio/64Audio/EmpireEars/etc.
This is the best Rosetta Stone about the 2 pin situation I've ever seen regarding .75vs.78 and what is "standard 2-pin"
Can someone sticky this?
