After a week of testing, I found a lot to love from both headsets. They're light and comfortable to wear for hours on end. And, most importantly, they both sound excellent. They were perfect for the dynamic audio design in Nier: Automota and Overwatch -- explosions and firing weapons all left an impact, and I couldn't hear any distortion once the action heated up. Other players had no trouble hearing me through the microphone, even while a loud TV was playing in the same room. On the PlayStation 4, the Arctis Pro Wireless sounded significantly better than plugging headphones into the Dual Shock controller. Both headsets also excelled at making music feel alive and vibrant, from Janelle Monae to high-resolution classical music on Tidal. You could hear plenty of detail and nuance across different genres, something that other bass-heavy gaming headsets often have trouble with.
But. I honestly didn't hear a huge difference between the Arctis Pro in Hi-Res mode and the lower quality wireless version. And yes, just to confirm, I was listening to 24-bit music from HDTracks and Tidal Hi-Fi. If I concentrated in a perfectly quiet environment, I could make out a tad more clarity from the wired headset, but it wasn't anything revelatory. I'm not too surprised, though. I've been dabbling in the world of high-resolution audio for years, and while I've heard some great recordings (Michael Jackson's Thriller sounds amazing in 96kHz/24-bit), I still prefer the flexibility of streaming music and my compressed (but still very high quality) library.
