The Bowers and Wilkins Pi5 S2 earbuds offer features like active noise cancellation and a waterproof design, which could be a deciding factor for use in noisy environments or during workouts. In contrast, the Moondrop Chu does not have noise cancellation but offers a cable with ear hooks and the capability for balanced audio with additional cables, thus potentially providing a more secure fit and higher audio fidelity for audiophiles. With the Bowers and Wilkins, you're paying a premium for brand reputation, build quality, and additional functionalities. If budget is a concern, the Moondrop Chu offers good sound quality at a more affordable price, but with fewer extra features. Give Feedback

Major HiFi
Chris Golembeski | January 2023
"Bowers and Wilkins isn’t looking to make an obscure, premium wireless bud catered specifically towards audiophiles. Instead, it seems apparent that they’re going for the crown: a cool and popular look, an easy and comfortable fit, and an engaging stage with a great balance that is perfectly suited for mainstream listeners and audiophiles alike."

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."
