Don't get the Speedlink Medusa seriously, I beg you.
I submitted a 1* review to the OCUK site about the Home edition, it hasn't been approved (yet) so I'll summarize the key points.
- They sound crap
- My £17.99 Sennheiser in-ear headphones produce more bass and superior sound quality
- If you turn your back on gunfire it loses all bass when the sound travels to the rear speakers
- Setting them up can be annoying and hard to get perfect
- For music they are absolutely terrible, they aren't much better for games and the rear speaker having no bass is very annoying
- They got many good reviews and glowing opinions from many people which is what lead me to the awful decision to purchase them, I've come to the conclusion these people have never owned a half decent pair of headphones before because the Medusa's are awful
- The 5.1 effect isn't all that good
I got a refund on mine, I tested them on two sound cards to make sure it wasn't my hardware or software causing the lack of bass and sound quality, I tried multiple fixes on the internet to add more bass and they still produced less bass than my tiny in-ear headphones.
