The Audio Technica ATH M40X are over-ear headphones with a wired connection, praised for their sound quality and soundstage. These would be perfect for critical listening and studio monitoring due to their detailed sound, but less suited for exercise, as they lack portability and sweat resistance. The Sennheiser Momentum True Wireless 3 are wireless earbuds with good sound quality, an excellent choice for convenience, active noise canceling for quieter listening during air travel, and better call quality. They are also more versatile for exercise due to their form factor and sweat resistance. However, the Sennheisers are more expensive, so if budget is a concern, the Audio Technicas provide high sound quality at a lower price point. Give Feedback
