Our Verdict

Sennheiser CX True Wireless

Sennheiser CX Plus True Wireless

The Sennheiser CX Plus True Wireless are the upgraded variant of the Sennheiser CX True Wireless and offer a slightly better overall performance. While both are fairly comfortable and well-built, the Plus have a more neutral default sound profile, which some users may prefer. They also have active noise cancelling, and while they outperform the base model, they only do an okay job of blocking out noise. The Plus also have a significantly better battery performance, and they support aptX Adaptive codec.
