According to what I've read, the P2 has a2dp support, so the S9's should run great.
I use my s9's with my ipod/bluetooth adapter, and my iphone.
You can link to two devices simultaniously. So say you are listening to music on your DAP, and someone calls, the music stops and you can answer the call. The music resumes as soon as the call ends.
They sound surprisingly good for a product that isnt dedicated to audio only.
The s9's are simmilar to earbuds. They isolate a decent amount depending on the tip you use, but not as much as iem's.
SQ wise, they supprised me. The have good, maybe slightly enhanced bass. I consider them better than shure e2c's, and the se210's I tried were only slightly better. You get what you would expect from 100 dollar iems.
I have two extra NIB, and I can give you a good deal. pm me if you are interested.
