If isolating external noise is a top priority for you and you're on a tighter budget, the Etymotic ER2SE can provide excellent noise isolation due to their deep insertion design, however, they can be uncomfortable for some users. On the other hand, if comfort, convenience, and features like touch controls and wireless connectivity are more important, the Sennheiser Momentum True Wireless 2 would be a better choice even though they are usually more expensive. Keep in mind, though, that true wireless earbuds can have latency issues with certain activities, such as watching videos or gaming. Give Feedback

Sound Guys
Lily Katz | April 2022
"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."

"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."
