Our Verdict
Sennheiser CX True Wireless
Sony WF-1000XM4 Truly Wireless
The Sony WF-1000XM4 Truly Wireless are a little bit better than the Sennheiser CX True Wireless. The Sony are comfier, blcok out more ambient noise thanks to their ANC feature, and have a longer battery life as well as a more feature-dense companion app. Conversely, the Sennheiser leak less audio and have on-board volume controls.
