In music systems, when we use headphone why the sound is reduced unlike it was in speakers. Please don't tell logical answers. I want technical reason.

can you rephrase your question? Do you mean it sounds different through your headphones, or less loud? Or do you mean; "why is there all of a sudden no sound from your speakers when you plug in your headphones"?
If it's the first... I don't know... Could be because they're bad or broken or are made to protect your ears from sound that is too loud and will damage your hearing...Or because it has a special "headphone listening"-mode
If it's the second... It's because there's a sensor of some kind (could be either mechanical or electronic depending on the hardware) that automatically shuts off the speakers because it assumes you don't want to use both speakers and headphones at the same time...
-edit- or option three;
If you mean why is the electrical signal of a headphone-output lower than that of a speaker output? It's because the speaker-units in headphones are much smaller than those in loudspeaker-units because they need to produce far less sound than loudspeakers so they require a much smaller electrical signal... Obviously...

The sound level is reduced because the output signal given to the headphone jack is usually lower then the gain on your receiver. This is due to the fact that most headphones can handle a max of about 3 watts and to reduce blower headphones manufacturers reduce the voltage on the headphone jacks output.

Hi Are you asking why the music from you speakers sounds different when listening through headphones.The main difference with headphones is that the the sound for each channel is isolated through each headphone speaker,and can't travel to the opposite ear. When listening to your loudspeakers each ear hears both speakers so you get 4 sound arrivals at your ears .The headphones isolate each channel from the opposite ear.The loudspeakers don't.The sound through headphones appears inside your head or slightly outside and in front.as apposed to the speaker sound which is definitely in front of you.
I hope this is what you wanted to know
Cheers.

They are really good and cool looking but there is no real difference other than looks and price.You can get good sounding headphones anywhere!

MDTOHM seems to have the right idea.
The voice coils in headphones are tiny compared even a small set of book shelf speaker's voice coils, and only need a fraction of wattage to power them.

Depends on who makes the headphones. These are the best ever...
