I'm just being objective

Free is awesome! I will be using them, and I'm still debating on returning the Purity's.
I mainly use ear phones when I'm on the bike. The Purity controls are big and easy to use, even with gloves on, just can't hear with the helmet on (smashes the earbuds into my ears). Without the helmet, they are the best sounding I've tried so far.
The Samsung's: I can hear fine with the helmet on, just can't work the buttons. Even sitting on the couch they are difficult to use, let alone when on the road.
I've been Scosche earbuds, but the volume control is a linear resistor. I have to set the volume on the phone to max, then use the inline slider. It works, but sucks battery life keeping the volume at max.
When I first got my WP, I hit every big box store, and electronic store in my area, and tried every brand that had inline controls. Everyone of them (android or iPhone earbuds) the middle button worked, but the volume control didn't. Which lead me to eye the Purity's, but they cost so much. When I finally saw the sale, I jumped. I forgot to think about the actual size of the buds.
