This headset is pretty damn good. As my first headset for my gaming PC, I find these are nice. They are built well. They are heavy but not too heavy. Overall pretty good. The adjustable headband is good too. The mic is somewhat short and without mic boost in windows it doesn't really pick up sound at all unless its right in front of your lips; which is only doable if your head is as thin as a sheet of paper. On the other hand, if you turn mic boost on and half the volume slider, it gives a great hearing comfort level and the mic picks up well for others to hear. Not only that but when you listen to music and theres a silence in the song you can hear a faint hiss. To combat this just take a quarter off the volume or half the volume on the in-line control and it sorts this problem. I recommend that anyway because with Mic boost you could defean yourself if you shouted to a team mate in a game lol.
Apart from those minor issues here is the major one for me.
Wearing Comfort. The headband is a tight one. Meaning it tries to push itself together. Basically it feels after a few hours that the headset is actually trying to squeeze your head. This isn't as bad as it sounds. Though one thing I didn't notice until I picked this up is that the ear cups are not made of the leathery type of synthetic material as the head bands, instead its a sort of sponge; which, when your ears get hot - which doesn't take long - starts to cause itching. Annoying thing is, due to it being foam its going to get hotter quicker than the synthetic leather-like fabric on the headband. Why speedlink didn't think of this is beyond me.
Audio quality is supreme!
Bass quality is real bass. It's not just empty thuds, it's geniune bassful beats, rumbles and kicks. This doesn't interfere with singing audio or percussion, with the higher pitch percussion coming through clearly over the top of the bass. The dynamic switching between L & R in the stereo is amazing and sounds great with this sort of audio quality and makes listening to music a joy. More so than speakers! You'd never want to go back to speakers after using these.
The mic is good, but as said it doesn't reach your mouth, so use Mic Boost and turn the in-line volume down a tad first. I don't think you can defean yourself but it depends on your own voice level and the volume of the source music/video/game.
When the Mic is on boost. Pickup is fantastic. It's crisp, clear and so very easy to hear.
Mic Broadcast Quality - 10/10
Audio Quality - 10/10
Comfort Quality 6.5/10
Hope this helped.
