Our Verdict
Sennheiser CX Plus True Wireless
Sennheiser MOMENTUM Sport True Wireless
The Sennheiser MOMENTUM Sport True Wireless represent a flagship's evolution of the Sennheiser CX Plus True Wireless. While both share water resistance, noise cancelling, EQ, and ear stabilizers, the MOMENTUM Sport are more refined in execution with an upgraded IP55 rating for the buds. Their case is water-resistant, while the overall ANC is more effective, too. Their refined shape and updated ear stabilizer design are more stable and comfortable, too. On the other hand, the CX Plus offer good value with a more consistent sound, a capable app, and a greater continuous battery life.
