If you're looking for superior sound quality for music, the Philips Fidelio X2HR is the better choice as it offers an excellent immersive experience due to its open-back design and high sound quality. However, they don't have a microphone for calls, and their open enclosure means they won't block out ambient noise, making them less suitable for noisy environments or on-the-go listening. On the other hand, the Sennheiser 450BT is more versatile and practical for everyday use, featuring active noise cancellation, a built-in microphone, and wireless connectivity with aptX Low Latency, which is great for TV and gaming without audio delay. They also have a longer battery life, foldable design for portability, and are priced lower, but they compromise slightly on sound quality compared to the Philips. Give Feedback
