If you prioritize sound isolation and accuracy, the Etymotic ER4XR earbuds may be the better choice, as they are known for their deep insertion design that provides exceptional noise isolation and precise sound reproduction. However, they may be less comfortable for long periods due to the deep ear insertion, and they lack wireless convenience. On the other hand, the Sennheiser Momentum True Wireless 2 offers the convenience of a wireless experience with good sound quality and active noise cancellation, making them suitable for everyday casual use in different environments. Yet, they may not match the sound fidelity of the Etymotics. So, if sound quality and isolation are your top priorities and you don't mind wires or a higher price, go for the Etymotic. If you prefer the freedom of wireless earbuds, a comfortable fit, and active noise cancellation for a slightly lower price, the Sennheiser would be the better option. 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."

What HiFi? | November 2022
"They are more comfortable and nicer to use than their predecessors, battery life is better and noise-cancelling is now included as part of the package. They’re easy to live with and you could happily listen to them for hours on end without reaching for the pause button. If your budget allows, your ears will be handsomely rewarded."
