If you prioritize sound quality for music, the Etymotic ER2SE provides superior audio performance, with notable noise isolation. However, it lacks a microphone and isn't wireless. The Soundcore Space A40, on the other hand, offers a balanced set of features with good sound, a microphone, and wireless connectivity, including a long battery life and wireless charging. If you need features like sweat resistance and active noise cancelling for exercise or travel, the A40 is more suited to those activities. Just keep in mind, both are similarly effective in noise isolation, and both are designed to be compact and portable. 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."

"The Anker Soundcore Space A40 is an excellent deal if you want affordable noise canceling earbuds with great sound. The baseline frequency response is enjoyable, and the many EQ presets to choose from plus the ability to customize your sound profile makes it good for pretty much anyone. The noise canceling is quite good, and the many ear tips to choose from ensure a good fit for the noise canceling and isolation to do its job."
