The Etymotic ER2SE earbuds, although less expensive, provide a high overall sound quality and exemplary noise isolation; they're ideal if you prioritize detailed audio and want a wired connection without active noise cancelling. On the other hand, the Sennheiser Momentum 4 headphones, despite their higher price, offer great comfort, longer battery life with wireless capabilities, and active noise cancelling, making them well-suited for traveling, extended listening sessions, and a variety of listening environments. Neither are optimal for exercise, but the Sennheiser has higher scores for calls, meetings, gaming, TV, and portability. Choose the Etymotic if budget and sound accuracy are key; opt for the Sennheiser if comfort, versatility, and convenience are priorities. 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."

Christian Thomas | January 2023
"If you're looking for a slightly more affordable set of ANC headphones in comparison to the Bose or Sony offerings: the Sennheiser MOMENTUM 4 Wireless is not a bad way to go. While its ANC is technically behind the other top-tier headphones, its sound quality is ahead of the pack—as is its battery life. Not bad for $350 USD."
