Oh dear

here is the reply from Fostex:-
We have no plan to have the HP-P1 approved for iPhone 5, but will do
for new products in the future.
well, that's interesting. Do they have a new updated product in the pipeline and have no reason to want to certify the HP-1 for this reason?
I'm amazed that it seems so difficult to find something suitable that's works with and is certified with apple?
surely I'm not the only person in the world to want to play music through good quality headphones :-0
Hi LeDave, to your question on the iPhone battery life. I don't (at the moment) play music through the Line out from my iPhone 5 so can't really advise on the battery life. I did notice that on my iPhone 4 when used through its line out would use the battery much quicker than the headphone socket. One or two colleagues at work initially moaned about the battery life on the iPhone 5, but it seems on par to the iPhone 4 as far as I can see. I think it's the same battery capacity, but its supposed to be far more economical and efficient.
Well I'm still tempted to get a HP1 (especially as nobody seems to stock the Sony PHA over here and I don't want to stump up £100s of pounds in import duty

(
why are these things sooooo difficult! Grrrrrr
