The WH-1000XM6 Headphones takes the performance lead with a 12% higher overall score, driven by its more shader cores, more of memory, and higher TFLOPS of compute power. In gaming benchmarks at 1440p, it delivers roughly 0% more frames per second across demanding titles like Cyberpunk 2077 and Alan Wake 2.

However, the WH-1000XM6 Headphones tells a compelling value story. At $400 versus the Px7 S3 Headphones's $400 price tag, it costs $0 less while delivering performance that's only 12% behind. Its of memory is still more than enough for 1440p and even 4K gaming in most titles.

Our recommendation: for the majority of gamers targeting 1440p or even 4K with upscaling enabled, the WH-1000XM6 Headphones is the smarter purchase. The Px7 S3 Headphones only makes sense if you need the absolute maximum performance for native 4K ray tracing, professional 3D rendering, or AI workloads where the extra VRAM and compute power provide a tangible advantage.
