If you're looking for affordability and have no need for wireless capabilities, the Sennheiser CX300S is a good value as they cost significantly less and offer decent sound quality along with a comfortable, wired design. However, if you value the convenience of true wireless earbuds, the Sennheiser Momentum True Wireless 2 might be worth the extra cost; they feature active noise cancelling, better call quality, and app-based customization for sound. You also get a significant leap in portability and convenience due to the absence of wires, and they are sweatproof and optimized for both Android and Apple devices. On the other hand, if you intend to use them for watching TV or gaming, the True Wireless 2 might not be the best due to their lower scores for these use cases. 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."

What HiFi? | November 2022
"They are more comfortable and nicer to use than their predecessors, battery life is better and noise-cancelling is now included as part of the package. They’re easy to live with and you could happily listen to them for hours on end without reaching for the pause button. If your budget allows, your ears will be handsomely rewarded."
