I picked up the PK3s a year ago and they had the Y-cord, I think they switched to the Y-chord a good while ago. They were really nice, warm sounding and detailed, good bass. However, the buds were too large for my ears, and got uncomfortable in extended listening sessions (might not be a problem for you). One side eventually stopped working, I can't remember why though. So I'm actually looking for the exact same type of earbud you are, just an alternative to the PK3 with no volume control.
