Hello Ram Guy.
Thank you for the update.
While I do believe that Corsair sold tens of thousands of V1500, you must understand that for every person who posts in this forum, there are many more that live with the problem believing it’s normal or they simply returned the headset to the reseller and/or bought one from one of your competitors.
So in the end, the problem could be bigger than you might realise.
Now, on to the problem itself…
First of all, I did a mistake in my first post. I incorrectly identified the problem as white noise. This is not the case. Well some white noise is present if we listen carefully, but it’s not that big of a deal. And, from what I found during my research on this problem, it’s normal for amplified headsets like the V1500.
So from now on, let’s refer to it as the High-Pitched-Whine-When-The-Microphone-Is Active problem.
Personally, I'm not sold on the software/hardware conflict hypothesis. I might be wrong, but hear me out.
I’ve done extensive testing. Windows XP, Windows 2K and 7 (Fresh and tried and true installs), Lenovo PC (4 different models), Dell PC, Asus laptop, 3 Custom built PCs. In the end, the high pitched whine is there as soon as the microphone is active.
It’s barely noticeable if the Corsair driver is not installed, but clearly present when the driver IS installed. Even on a fresh install of Windows 7.
Now, onto why the Corsair employee who tested my second replacement headset did not hear it.
Is it better than average hearing on my part?
Maybe, but my wife can clearly hear it and so my co-workers. So, it's not just me.
Was there a lot of noise when he tested it?
I usually game in my home office where it’s quiet. Not at work where the phones are ringing and dozens of peoples are working/talking. Maybe he simply missed it.
But, one trend I start to see is that many people who are posting in this thread are living outside of the US. Myself included (Canada).
Could the components of the V1500 be benchmarked or calibrated for US standard power grids?
Could the V1500, being an amplified headset, pick up something from non-US power grids and amplify it somehow via the Corsair Driver or the headset itself?
Personally, at this point, this is out of my league and it’s up to Corsair’s Product Dev Team.
The only other suggestion I can think of is for a Corsair employee (with excellent hearing) to test a V1500 in a sound proof booth and repeat the steps I’ve mentioned in a previous post to replicate the problem.
If he’s not hearing the high pitched whine when the mic is activated, then I’m out of ideas.
Maybe a BBQ at my place so i can do a live demo?
