The Bowers and Wilkins PI7 offers better soundstage and mic quality, which is great for an immersive audio experience and clear calls but comes with a premium price tag. In contrast, the Sennheiser 450BT, while being more affordable, boasts longer battery life and active noise cancelling for focused listening, making them suitable for travel and noisy environments. The over-ear design of the 450BT generally provides more comfort for extended periods, whereas the PI7's earbuds are more portable. If low latency is important for you, such as for gaming or watching TV, the PI7 offer this feature. Choose the PI7 for premium sound and mic quality with extra features, or the 450BT for cost savings and better noise isolation. Give Feedback

"The primary selling point of the Bowers & Wilkins PI7 is the charging case that can transmit audio from any analog source to the earbuds. If you have a very specific and clear need for that feature, then the Bowers & Wilkins PI7 is for you."

"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."
