The thing is my K750's volume is so low when playing Mp3's like two times lower than normal output. I got this HPM-70 headphone set which also allows me to connect the phone to any earphone but there is no difference in volume. When I connect it to a sterio I have to turn up the volume to full to get a "resonable" output.

I did notice something though, when I connected my phone to a multi-media speaker set and plugged my earphones to ITS output the volume is so amazingly high and blows my ears! And NO quality reduction what so ever! The multi-media speakers amlifier seems to be boosting the output. I'm trying to make something portable out of the circuit but as it needs 9V I'm not sure if it will be exactly "portable" and "affordable".

I heard that this so called "low volume" is due to a law. Never the less is there a way to modify the phones firmware so I can get the volume to "normal" levels on the earphone.

Thanks

you should change the acoustic then. it increases your volume considerably.

the path: FS=>ifs=>settings=>acoustic

do this with xs++(i recommend the v3.0)

Hey, you get a low sound also coz as per the software setting, that is tha max limit to which the sound level can go.

You will have to change the drivers of that phone to get a higher output, however please make sure the drivers are safe before you install them, or else you could loose the current settindgs as well.
