If you prioritize high-quality sound for music, gaming, and video, along with features like active noise cancelling, and are willing to pay a premium for it, then the Master & Dynamic MW75-Neuro would be a better choice. It also offers wireless capability, long battery life, and integrations for optimizing mental health and focus. However, if you're looking for a more budget-friendly option that's still good for music and casual use, and don't need wireless connectivity or noise cancelling, the Sennheiser CX300S earbuds would be suitable. They are more portable and offer a fair level of noise isolation, but they aren't designed for exercise use and lack a microphone suitable for calls. 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."
