Sennheiser CX True Wireless: easy-to-use earbuds

  • Ideal for home use
  • Full bass
  • User-friendly app
  • Design a little too big

The Sennheiser CX True Wireless are earplugs without too much fuss, but therefore excel in the basic characteristics. They are ideal for on the road and at home, but I think the design is just a bit too big to use the earbuds for other purposes.

Ideal for home use
When I want to listen to music, I put the earplugs in my ears. It is important to twist them in, otherwise they will not stay in place. When I turn them in, they fit well. During long listening sessions of more than 2 hours, the earplugs do not hurt my ear canal. They just aren't sturdy enough to be really active with it. For example, these earplugs are not suitable for running or exercising, but they are ideal for at home and on the go.

Full bass
The earplugs deliver a rich sound and I especially notice the full bass. This one isn't too overpowering, but it packs a nice punch. In addition, the medium and high frequencies are reasonably balanced, which produces a beautiful sound. When I want to make the bass more powerful, I download the app. Here I adjust the sound completely to my own taste. This allows me to listen to a suitable sound quality for every genre.

User friendly
In the app I not only adjust the sound, but also all kinds of other settings. This way I determine how the touch control works. I find this ideal and it makes the earplugs very user-friendly. Even without adjusting the controls, I'm happy with how I control my music via the earbuds. For example, I adjust the volume by holding my finger on the left or right earbud, which is not common with other earbuds.

Powerful sound for a good price

  • Powerful sound through aptX
  • Fit comfort in ears
  • Control/personalize via ears
  • Too bad no ANC but no big loss

As I am used to from Sennheiser (before Sennheiser headphones) powerful sound with aptX with good loud sound (bought Beats Studio Buds yesterday and immediately returned), nice design with long battery life.

  • Fantastic sound

  • Just a little too big design

Excellent value for money. Calling in a noisy environment works great. The app is ideal for coupling and equalizer.
