The Etymotic ER4XR boasts superior noise isolation, which would be advantageous for air travel or quiet listening environments, but it is not wireless, making it a less convenient choice for exercise or mobility. On the other hand, the Razer Hammerhead True Wireless has a comfortable fit, is suitable for gaming due to its low latency feature, and supports wireless charging, offering greater convenience for active use and gaming sessions. The Razer also supports AAC codec, which is preferable for Apple users. However, if audio fidelity is a top priority and you're fine without wireless connectivity, the Etymotic may be worth the higher price. Give Feedback

What HiFi?
What HiFi? | May 2015
"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."

The Verge
Chris Welch | August 2019
"This latest set is more “Pro” than not in both looks and features: they offer active noise cancellation, a low-latency gaming mode, and have switched to a in-ear design with silicone tips. Just like many of the company’s laptops and gaming accessories, the 2021 Hammerhead True Wireless include Razer’s full Chroma RGB system. It makes for what Razer calls “the ultimate wireless earbud flex.”"
