Review: The Sennheiser CX is different than the brilliant Sennheiser CX 400BT. Test and comparison, also vs Soundcore Life P3, Lypertek, Melomania 1+.
The HearWiki takeAI-condensed
The Sennheiser CX True Wireless earbuds deliver solid audio performance with a punchy bass response, though the tuning leans slightly less airy than some predecessors. They offer excellent call quality, a comfortable IPX4 rating, and a strong 9-hour battery life per charge, with the case extending total playtime to 27 hours. While the design may not turn heads, the app support, customizable EQ, and reliable Bluetooth 5.2 connectivity make them a practical choice for everyday listening.
