If you prioritize wireless convenience and active noise cancelling for versatile use including exercise or commuting, the Sennheiser 450BT is a cost-effective choice with a significant price advantage and good overall sound quality. It also has a built-in microphone for calls. However, if you seek the highest audio fidelity for critical listening at home and don't need wireless functionality, the Sennheiser HD600, despite being pricier, offers superior sound quality and comfort but lacks features like Bluetooth connectivity, active noise cancellation, and a microphone. Both models have their merits, so your choice should align with your primary use case and budget constraints. Give Feedback
