Open backed headset

[SimplyGone]

Ok,  So about a year ago i bought myself a cheap headset.  The Roccat Renga.  It was only £30-35 or something but it was my first pair of open backed headphones.   Anyways, it's died.  I really liked the natural sounds that they produced.  I only ever ran it off my front audio jack.  Now I've been doing some digging for a replacement and have come across These:

 

I was going to pair them with the microphone that's built in to my webcam.  Or failing that just get a cheap USB mic.  I'll only be using the mic for Skype calls so doesn't need to be 'Studio Quality'

 

Does anyone have any other suggestions?  I'm willing to spend about 100 quid total this time.

 

I'm not fussed about just using the front input as i plan to get an AMP and DAC later on.  But as the headset has died on me i need to replace this first.

 

Edit:

 

I should just add  I have three options when it come to driving the headphones: 

 

The onboard Audio from my motherboard (MSi Krait Z170)

An old Tascam US100 that i can dig out the bedroom

Or a Soundblaster Audigy RX

 

I don't mind which of these i use until i get my AMP/DAC combo
