The Audio Technica ATH M40X offer an impressive sound quality and soundstage, making them ideal for music and TV where a broad and immersive experience is sought. However, they're not as practical for exercise or travel due to their size and lower portability. In comparison, the Etymotic ER2SE provide excellent noise isolation and are more suited for environments where you want to block out background noise, like during air travel or in loud places. They are less comfortable for extended periods, but their small size makes them more portable. Both lack a built-in microphone, so you should consider separate solutions for calls and meetings. If you prioritize tops in music listening and a more expansive sound, the Audio Technica headphones are the way to go, whereas for superior noise isolation and portability, the Etymotic earbuds are the better choice.

"Etymotic isn’t playing around: it takes audio seriously and has mastered the art of the noise-isolation earphone. Sure, the fit of the earbuds looks silly but it’s a signature Etymotic thing and could be considered charming by some. If you’re looking for best-in-class audio for a realistic price, the ER2SE is it."
