First I'll start with the content of the package:-Headphones (obviously).-Two cables: one 3.5mm and one USB-C. USB-C cable is needed for 7.1 audio but it still sounds great with the 3.5mm one.-Adapter for audio jack for people who still have laptops or computer chassis that use individual jacks for mic and headphones.-Manual and warranty.-Nice bad to carry everything on.It's nice that the headset came with the adapter and a bag, much appreciated.I'll continue with non-sound characteristics:This headset is really comfortable for big heads. I've always had rpboelsm with headsets as they don't fit or barely do it and end up exerting too much pressure over my ears (plus having not so comfortable shape on the pads) so my ears ended up hurting a lot after an hour or so. This is not the case with these headsets, I've been able to stay working with them on for hours with no discomfort or pain whatsoeverNow going for the sound stuff:This headset definetely has really good audio quality, specially for this price point and it does support 7.1 audio. However there are a few caveats:-7.1 Audio only works through USB (not a problem).-You can either select to use 7.1 audio mode or HI-FI mode, being HI-FI optimized for music (7.1 mode without using equalizer makes music sound terrible).-Noise cancellation isn't that good. I can still hear the traffic outside my appartment through my mic.As for having to either use 7.1 mode or HI-FI mode, I circuntented it by enabling 7.1 mode and adjusting the equalizer to sound almost exactly the same as HI-FI mode (I could have probably gotten the same sound, by I had spent an hour on it so I didn't want to continue, it sounds great anyway). I used some normalized sounds that help with finding the right balance for audio.If you are interested in which equalizer adjustment I used, is this:30hz: -460hz: -5120hz: -1250hz: -2500hz: 01000hz: 02000hz: 14000hz: 18000hz: -616000hz: 4I hope this feedback helps.
