If sound quality and noise isolation are priorities, the Sony WF1000XM3 offers superior performance and features like active noise cancelling that the Sennheiser CX300S lacks, making them suitable for air travel and busy environments. The Sony also comes with app customization options, a longer battery life, and are optimized for both Android and Apple devices, which the Sennheiser doesn't support. However, if price is a major concern and you prefer a wired connection, the Sennheiser CX300S is a more affordable choice and provides a decent listening experience, albeit with fewer advanced features. The Sennheiser set may also be better suited to less demanding environments where active noise cancellation isn't necessary. Give Feedback

Major HiFi
Carroll Moore | April 2019
"Sennheiser offers impressive bang for your buck when it comes to the CX 300S. Built like a tank and sounding surprisingly good for such a budget-minded earphone, the CX 300S out-classes many of its would-be competitors. Functional but beautiful, it’s the perfect in-ear listening solution for anyone who wants to hear everything and look good doing it."

Sound Guys
Lily Katz | November 2022
"Wireless earbuds are a dime a dozen, and the Sony WF-1000XM3 makes it easy to justify the cost. The design and comfort are good, and the connection strength is consistent. While the lack of aptX or LDAC support is a big drawback, DSEE HX processing improves low-quality audio files. If you want stylish active noise canceling (ANC) earbuds, the WF-1000XM3 needs to be at the top of your list."
