Literally the worst piece of software I have ever had the displeasure of using.
I purchased my 1500v2 a little over a year ago and the experience has been so terrible that I will not be purchasing another corsair product again. Which is saying a lot coming from someone who has been accused of being a corsair fanboy.
I'm using equalizerAPO to increase my mic volume by 5db, which is still too quiet cranked to 100% in its own settings, and to decrease the headset volume by 22db - which I still have to leave at 2% in windows or it blows my ears out. Any time I activate the headset my audio captures a huge, one sided pop from the left along with hissing, which I assume is conflict from the mic, which then gets transmitted through my streaming software.
I have installed corsair drivers, razer drivers, window drivers and tried various work arounds and fixes over the year.
For posterity, I decided to post and say I am done.
Love my k70, Corsair, but it will probably be the last product I own.
edit; Just replaced the 1500v2 with a cloud ii. It's night and day. Should have done it as soon as I had to "try and fix" the corsair. Is corsair ignoring these driver issues because they're ashamed of what they created? I don't blame them.
