The Audio Technica ATH M40X is a great choice if you're looking for high sound quality on a budget, particularly for music and TV where it excels in soundstage and overall audio performance. Being wired, it's less suitable for exercise and lacks the portability and convenience of wireless options like the Sennheiser Momentum True Wireless 2. Sennheiser's model, despite being pricier, offers better features for an active lifestyle like sweat resistance and active noise cancelling, making it ideal for use during exercise and travel. Additionally, if calls and meetings are a priority, the Sennheiser's integrated microphone provides clear audio for communication. Give Feedback

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."
