Please note that if your phone doesn't work with the HF3, it will not work with the HF2 (opposite is also true). If you do know your phone supports headsets, you can always get an adapter that swaps out the ground and mic contacts. MEE sells such an adapter for 10 dollars + shipping: http://www.meelec.com/MEE_TRRS_Adapter_for_P_Version_Headphones_p/adptr-trrs-35.htm
I should have been more clear. The HF3 is SPECIFICALLY designed for the iPhone in that it has volume controls. The HF2 works on the iPhone, but has no volume controls, just one button that pauses or plays your music/answers or hangs up phone calls. Etymotic introduced the HF2 first, marketed mainly towards the iPhone (which is when I purchased them). They then later came out with the HF3 which are the same thing but with the addition of volume controls. The volume controls on the HF3, I believe, aren't meant to work on other devices besides those running iOS.
I owned the HF2, and now I have the HF3. Used both with an iPhone.
To the OP, I'm not sure if you should be experiencing those problems just because the HF3 is marketed towards iPhones. I think they say they are for iPhone just for the controls, but I doubt that there is a difference in sound quality if you are using a different source (just controls might not work). You might have a defective pair... My first pair, the HF2's, had a malfunctioning mic which only worked when the headphones were plugged into the phone at a certain rotation, but I was too lazy to send them to etymotic haha.
