If price is a major factor for you and you primarily listen to music, the Etymotic ER2SE will be a great choice due to their lower price and very good music score, but they lack a built-in microphone and wireless capability which could be inconvenient for calls and on-the-go use. On the other hand, if you value wireless convenience, better call quality, and features like active noise cancelling for various environments, the Sennheiser Momentum True Wireless 4 would be better despite the higher price. The Sennheisers also have an app equalizer, better durability, and are sweatproof, making them more versatile for different situations like exercise or travel. 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."

Andy Madden | January 2024
"It’s fair to say our brief time with the Sennheiser Momentum True Wireless 4 was a generally positive one. Comfort levels seem similar to what we have experienced before and the general flavour of sound was to our liking although we need to get a pair in to test and put up against the big rivals at the money from Bose and Sony. It could be an interesting contest."
