Choosing the Audio Technica ATH M30X will give you a generally higher sound quality and a wider soundstage, beneficial for an immersive music listening experience, plus they are considerably more affordable. However, the Etymotic ER4XR offers superior noise isolation, a smaller, more portable form factor, and a detachable cable, which might be preferable for travel or loud environments. The ER4XR's build quality is also rated higher, meaning they could be more durable over time. If you're watching TV, gaming, or involved in calls and meetings, the ATH M30X provides a more suitable experience, whereas for music, the ER4XR has a slight edge. Choose the ATH M30X for broad usage and a tighter budget or the ER4XR for high noise isolation and portability at a higher cost. Give Feedback

Jasper Lastoria | August 2023
"The Audio-Technica ATH-M30x is a great choice for anybody that needs a decent set of over-ear studio monitors. While the frequency response is not totally spot on, it works for basically every situation reasonably well. The sound quality and reasonably good comfort promote its candidacy as a great pick for $69 USD."

"The Etymotic ER4XRs' top qualities are the detail and definition of the midrange, rewarding the closest listening. While the soundstage is large rather than gigantic, the excellent separation and spatial precision mean you can dive deep into music just as much as when wearing a pair of full-size open-backed headphones."
