If you prioritize wireless convenience and active noise cancelling for a busier environment such as commuting or air travel, the JBL Tune Flex might suit you better. They also offer better performance during exercise thanks to their sweatproof certification and provide a low latency mode, which is advantageous for gaming. However, the Moondrop Chu earbuds are a budget-friendly option with very good mic quality for calls and meetings. They feature a cable, which eliminates battery life concerns and could provide a more stable connection for uninterrupted listening, important if you mainly use them for music or video at home or work.

"JBL is offering a similar design and arguably better resolution than the more expensive AirPods 3rd Generation. Add to that a comfortable and versatile fit, an equalizer and pretty decent ANC, and you’ve got a quality wireless earphone. I would have loved longer battery life and more crystal calls, but for the price, you can’t complain. A solid deal overall."

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."
