If you prioritize wireless connectivity and the ability to use headphones for a variety of activities including exercise, the 1More Sonoflow is the better choice with its sweatproof certification and longer battery life; however, they're more expensive. On the other hand, if you seek superior sound quality for music and calls, along with a lightweight option at a budget-friendly price, the Moondrop Chu excels in these areas but lacks wireless capability. Neither option is tailored for gaming or watching TV due to noticeable latency issues, which may disrupt syncing of audio with visuals. The 1More also features active noise cancelling for better sound isolation, which the Moondrop Chu does not offer. Give Feedback

Headphonics

Michael | January 2023
"The SonoFlow is cheap and fun, without going too far into being overly warm or annoyingly grating, or sharp sounding. The ANC features are lovely with strong app integration and excellent battery life."

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."

About Moondrop

Moondrop is a Chinese brand of smart audio equipment, portable audio players, earbuds and headphones started in 2015. During the last few years they have become one of the major players in what is lovingly referred to as the Chi-fi market, the bulk of Chinese companies that have managed to actually compete with the western manufacturers in both prices and superior quality. Products such as the Blessing II, Chu and Kato are among the most popular offerings of the brand, more popular among those users that wish for good quality audio that won't break the bank. Besides audio, the brand also works in what they call the ACGN field (Animation, Comics, Games and Short Novels).
