My P1 are also perfect. And super comfortable, one of the most comfortable I've ever worn, I can even sleep on my side with them, which is rare for me.
Comfort issues people are having are probably related to the tip, and the tip placement. The bore on the p1 is pretty long, but the edge for where the tip should be is very close to the end, so I just pushed my tips over that edge/lip almost all the way to the housing. This improves the sound as it bring the opening closer to your eardrums, and also helps with isolation.
Tips: Until today I was using Large SpinFits (my normal tip size is M) but I think spins runs just a few mm smaller than others, and I need more of that soft silicone to get a good seal. However these Symbio W tips just arrived today (from ebay) and goddamn are they good. As close to the Sony silcone and foam hybrids as ever seen, and maybe better??? The ebay seller I got them from is sold out, but hopefully the symbio site will be back online soon with restocked W's (they were sold out there recently).
Here's the link, but site is down for maintenance right now:
