If you're highly active and want features like a heart rate sensor, accelerometer, and exercise analysis, while also needing earbuds that stay secure during movement, the Mojawa HaptiFit Terra would be a fit, especially since it's sweatproof and bone conduction allows situational awareness. However, for a casual listener seeking better sound quality, particularly in quieter environments, or who prioritizes music and TV over workouts or calls, the Sennheiser CX300S offers a sound-isolating experience at a lower cost. The Sennheiser lacks the bells and whistles of fitness tech and wireless convenience but provides a reliable wired connection with no worries about battery life. 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."
