If you prioritize an immersive music experience and noise isolation, the Etymotic ER4XR stands out with its in-ear design providing superior noise isolation but lacks built-in controls for convenience. However, they are wired which can be a limitation compared to the wireless Bose QuietComfort Earbuds II, which offer comfort and quality sound, including active noise cancelling and easy-to-use built-in controls suitable for exercise and travel but may have a shorter battery life. Conversely, the Bose is a more versatile, modern option that also has an application for sound customization, making it suitable for both Android and Apple users. Give Feedback

What HiFi? | September 2023
"Bose’s flagship wireless earbuds were never going to be cheap, but the question was whether they’d be competitive in an area of the market where rivals have never been more capable. The fact that the company has not only managed to implement a successful redesign, but also push the envelope for noise-cancelling and sound quality in such a highly competitive category simultaneously is truly impressive."

"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."
