If you're looking for over-ear comfort with the option to use a wired connection and prioritize longer battery life, the Sennheiser 450BT is a suitable choice, particularly for gaming and TV with its aptX Low Latency feature. However, for portability and an edge in call quality, the Sennheiser Momentum True Wireless 2 earbuds, though slightly more expensive, might be preferable and also offer active noise cancelling to help isolate you from ambient noise. The Momentum also benefits from sweat resistance making them a better option for exercise, plus app customization features for sound tweaking. Both have good build quality, but the Momentum's touch-sensitive controls provide a more modern user experience. Give Feedback

Lily Katz | March 2022
"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."

What HiFi? | November 2022
"They are more comfortable and nicer to use than their predecessors, battery life is better and noise-cancelling is now included as part of the package. They’re easy to live with and you could happily listen to them for hours on end without reaching for the pause button. If your budget allows, your ears will be handsomely rewarded."
