The Sennheiser 450BT is a more affordable, closed-back, over-ear headphone with wireless capabilities, a built-in microphone, and active noise cancelling, making it versatile for on-the-go use, calls, and commutes. With aptX Low Latency support, they are also suitable for gaming and TV without significant audio delay. On the other hand, the Sennheiser HD800S offers superior sound quality and comfort, with an open-back design that provides an exceptional soundstage, ideal for dedicated listening sessions. However, they are more expensive, lack a microphone, and are not intended for outdoor use or noisy environments due to their open-back nature and lack of active noise cancellation. 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."
