If you prioritize wireless connectivity and active noise canceling for listening on the go or in noisy environments, the Sennheiser 450BT is the better option, but consider that it may be less suited for intense gaming due to a bit higher latency. The HyperX Cloud II, being wired, excels in gaming with a boom microphone delivering excellent quality for in-game communication. For long music sessions, the Sennheiser might not be as comfortable as the HyperX, which also boasts a slightly higher music score. Choose the Sennheiser for its portability and long battery life, but if gaming and calls are your main activities, the HyperX may serve you better. Give Feedback
