If audio quality is your top priority, especially for music, the Etymotic ER2SE offers superior sound but at a higher price. However, the Moondrop Chu might be preferable for calls and meetings due to its better microphone quality and is more affordable. The Moondrop Chu also seems to have better comfort and is slightly lighter, with larger earbuds, which can affect fit. Neither has wireless capabilities or active noise cancelling, but the Etymotic has higher noise isolation. The ER2SE has a detachable cable, which could be beneficial for durability and serviceability, whereas the Moondrop Chu does not. It's important to consider these differences when selecting between high sound quality and better call clarity versus comfort and affordability. 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."

Sound Guys

Jasper Lastoria | September 2022
"These budget buds put the pressure on those premium priced in-ear monitors to really justify the cost disparity. Offering excellent sound quality at any price, the Moondrop Chu is both a perfect entry into the audio enthusiast hobby, and an all around good pick for music fans."
