Hey, I bought the HF3 a few days ago and didn't realise they were specifically made for iphones/ipods. I have a samsung galaxy s.
When I first put them on in the tube, I noticed that they sounded very distant and muted.
Last night I was experimenting, and I found that when I press and hold the middle button on the volume control, the sound becomes much fuller and much better.
This must be something to do with compatibility. I am considering taping something over the middle button so that it is permanently pressed, because they sound pretty terrible when it isn't pressed. Is this a good idea, or could it damage them ?
the reason this works is that your phone has the TRRS contacts mapped to left/right/mic/ground (in that order), but the HF3, which is designed for the iCrap has its TRRS contacts mapped to left/right/ground/mic. The middle button of the HF3 short circuits mic to ground. The reason it sounds "distant and muted" when the middle button is *not* depressed is because you are routing the audio output through the microphone. When you press the middle button, you remove the microphone from the system and things sound as they should. You can run it with your button hack permanently without worries, but I wouldn't be satisfied with that solution. Instead, I bought male and female TRRS connectors, some shielded cable, and soldered my own adapter. It took about 1/2 hour to do. You would need cable with 3 leads plus shield.
