Etymotic HF2 + Iphone 4?

Hi guys, I just wanted to know if the HF2 works with the new iphone, because i've seen some very mixed responses online but I don't understand if they're complaining about the buttons not working or no sound coming through the earpiece.

I don't really care if the buttons are a bit unreliable as long as you still get the music out and on that note, do the Etymotic HF2's work with any MP3 player (without the use of the buttons and mic).

I also wanted to ask if they've started selling the HF3's in the UK yet because I can't find them anywhere.

Thanks everyone in advance.

P.S. I've heard that etymotics tend to be a bit weak on the bass, would anyone reccommend using the device equaliser, because I could swear that all phone equalisers do is ruin the music?

Thanks for the quick reply (and useful information regarding the equalisers) but they don't sell the MC3 or the HF3 in the UK, the only ones i've seen are the ER-6i, HF2 and HF5 (and the er 4p which is outta my price range unlike the other three which all cos the same)

That's great, thank you. I'm not going to bother getting the HF3 or the MC5 because they are going to be a load more expensive when they finally come out. I'm just getting the HF2 so I don't get mugged! Plus it's way more convenient to forward etc. using a button than taking it out
