Choose the Sennheiser 450BT if you prefer wireless convenience for TV and gaming with good sound, active noise cancelling, and a comfortable over-ear form. They have a longer battery life, integrated mic, and foldability for easier transport. However, if superior music quality is your priority and you don't mind using cables, the Sennheiser IE600 offers top-notch audio with a more durable build but lacks wireless functionality and noise cancelling. Both are suited for travel, but the 450BT provides better isolation for loud environments. The IE600, while more expensive, might appeal for its high-quality sound in quieter settings. 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."
