The AKG K712 Pro is designed for critical listening with a premium price, open-back design, and high comfort, but it's not wireless and lacks a microphone, making it unfit for calls. The Sennheiser 450BT is more affordable, provides a closed-back design for better noise isolation, wireless connectivity with AptX Low Latency, active noise cancelling, and a good microphone, suitable for calls and casual use. If you prioritize audio fidelity and use them in a quiet environment, prefer the AKG. For versatility, noise cancellation, and use on the go, Sennheiser is the better choice. Give Feedback

"The Sennheiser HD 450BT is a very good pair of headphones for the price, noise canceling is good and sound quality is great—quite rare at this price point. Like any product, this headset isn’t without its faults."
