Our Verdict

Sennheiser CX 400BT True Wireless

Sennheiser CX True Wireless

The Sennheiser CX True Wireless are better than the Sennheiser CX 400BT True Wireless for most uses, though the two pairs of headphones are similar overall. The CX have longer battery life and an auto-off timer to help conserve power when not in use. Their companion app also has a slightly wider range of configuration options. Conversely, the CX 400BT offer better microphone recording quality.
