Should I get new headphones?

I'm currently using the Razer Megalodon headset on my machine at my dad's. When I'm at my mom's house I don't want to take the headset with me everytime so I'm looking for a new one. At my mom I am using the creative fatality gaming headset (with no mic, it broke). So I am looking for a new headset to use at my mom's. I also have the RHA MA350 IEM's that I take with me everytime I go somewhere. When I plug the RHA's into my machine I can hear static and the noise from my fan's.

So I am looking for new headphones that are better than the fatality's and the RHA's.

The other possibility is also an external sound card (a DAC if I am correct) that takes away the static from my RHA's when I plug them in. I am also planning on getting my own place in about 2-3 years so a more permanent DAC or good pair of headphones would be nice for a more futureproof setup. 

My budget is about 70-100 Euros but I am willing to pay a bit more if it's a big improvement over the lower cost.

Thanks,

If yuo haven't already i'd look at Logans headset videos.
