Amplifier? Switch?

Thank you but is there such equipment that I can leave my speakers AND headphones plugged in and change the output via a switch or button? So I don't have to plug my headphones in everytime I want to use them??

 

At the moment I just have some cheap £60 "Trust GXT 38 120W 2.1 Subwoofer Speakers"

These also need a huge upgrade...

Generally, but not always, the amps used for HP and speakers are different or there is some additional circuitry to reduce the power to the HPs. Your needs can easily be met if you look for individual amps sharing the signal or a pre amp that has switched outputs. Alternatively look for a speaker selector switch switch to put into the middle.
