Sony WH-1000XM4 vs Sennheiser MOMENTUM 4 Wireless

The Sony WH-1000XM4 Wireless have a slight edge over the Sennheiser MOMENTUM 4 Wireless due to the better noise isolation on the Sony. While both are premium headphones, the Sony are a bit more comfortable; their ANC blocks out more ambient sound, and they support LDAC, which is a Bluetooth codec for streaming high-quality audio. They also have a virtual soundstage feature to help make your audio seem more immersive and spacious. However, the Sennheiser are no slouch: they also have a much longer continuous battery life, and they support aptX Adaptive, which is a Bluetooth codec that dynamically adapts to your audio content to give you either lower latency or better audio quality. If you want USB audio, only the Sennheiser boast that feature, but their ANC isn't as strong as the Sony.
