If you're referring to the adaptor someone else mentioned buying here, the concern was going from a 3.5mm SE to a 4.4mm balanced, due to how it's wired internally. But 4.4mm balanced to 3.5mm balanced should be fine, and vice versa provided the manufacturer knows what they're doing.
I hope Sony will be releasing some adaptors themselves too
No I mean if you want to adapt a 4.4mm balanced iem cable to us it on DAP with 3.5mm SE jack
