Corsair Virtuoso RGB not that Virtuoso

Hello everyone, I'm subscribing just for complaining and warn you from buying this product which is supposed to be the best Headphones from Corsair.

I really really really hope to be wrong so I'm going to list the issues I'm having with this headphones and then listen to your opinions.

I've received my Virtuoso 2 days ago.

First issue: BATTERY LIFE.

100% Brightness, full charged. Goes from FULL to DEAD BATTERY in 4.30 hours. They claim around 20 hours. I'm getting 4.

Do you think it's normal?

Second issue: iCUE Compatibility

I don't know what's wrong with this Software but the USB receiver is blinking RED all the time (stops after a few minutes), even though the headphones are connected. It's supposed to be steady white. If I close iCue, it goes to Steady White. so it's clear an iCue issue, really?!

Third Issue: MAC compatiblity

I got two computers, one for work, one for the rest. Well, I use a Mac for work and the idea was to use this headphones for that. I check the website, and look! iCue is fully compatible with Mac and also this Corsair.

I install the SW, everything is fine. I try to play a video on Youtube, and before even reproducing sound, I head a STATIC NOISE / WHITE NOISE in my ears. Every time there's a media session with audio (so song, or video), a STATIC NOISE appears. UNUSUABLE.

Guys, I really want you to prove me I'm wrong, so I can start appreciating an d fix these headphones; but, what I think is that I've either received a defective product or it's a defective model.

Already sent a Ticket to Corsair, but I'm not receiving answers.

See you and have a nice day :)
