Just got this headset earlier today, and my first impressions of it were great. As with all SteelSeries products, the build quality and customization options you have with SteelSeries Engine 3 are great, but as I started listening to music on my PC to test the sound quality I was shocked by how bad it was. Two things to note though, 1. it sounds amazing when i use the headset on my phone, like best sound quality from a headset I've ever had, and 2. this same thing has happened to me before with the HyperX Cloud II's- terrible, headache inducing sound on PC, great sound on mobile. I assume this means it is an issue with my PC, but the same thing also happened on my sister's PC (for both the Arctis Pro and Hyperx Cloud II). The only similarity between our computers though is that we both used to have the same Razer headset, and had the Razer Synapse software installed previously. I don't know if that can interfere with different brand headsets, but I thought it was at least mentionable. Any help you may be able to offer would be greatly appreciated.
