Our Verdict
Apple AirPods Pro Truly Wireless
Sennheiser CX 400BT True Wireless
The Apple AirPods Pro are significantly better headphones than the Sennheiser CX 400BT True Wireless. The Apple are more comfortable, have a better-balanced sound profile, and have a great noise isolation performance thanks to their ANC feature. Their battery performance is better too, and they have an H1 chip so it's easy to pair with different Apple devices. However, the Sennheiser have a better-performing integrated mic, and their companion app offers a lot more customization features.
