If cost is a major concern, the Moondrop Chu provides good sound quality and is budget-friendly but lacks wireless connectivity and features like active noise cancelling. Sennheiser Momentum True Wireless 4, on the other hand, is more expensive and offers high sound quality with added features like active noise cancelling, low latency for gaming, and app customization. The Sennheisers are also suitable for a variety of uses, including exercise and air travel, with better portability and sweat/dust resistance. If you prioritize audio quality and features over price, the Sennheisers are better suited for diverse and active lifestyles. Give Feedback

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."

What HiFi
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."
