The Sennheiser CX Plus True Wireless are the upgraded variant of the Sennheiser CX True Wireless. They have an improved continuous battery life, support aptX Adaptive codec, and have an active noise cancelling (ANC) system. However, aptX Adaptive is only available on some devices, and their ANC only does an okay job of blocking out ambient sound, so it may not be enough for noisy commutes. They also have a warm and bass-heavy default sound profile, although if you prefer a different sound, their companion app has a graphic EQ and presets so that you can customize them to your liking.
Our Verdict
The Sennheiser CX Plus are alright for neutral sound. Out of the box, they have a warm and bass-heavy sound profile that delivers extra boom to your mixes. However, vocals and lead instruments are dark and veiled in comparison, which may not be ideal if you listen to content like pop or podcasts. Luckily, their companion app offers a graphic EQ and presets so you can adjust their sound to your liking.

That said, the earbuds have an ANC system that can block out a fair amount of background noise.
