Wireless headphones without active noise canceling are becoming less relevant. Disconnecting from the outside world and being alone with your thoughts or focusing on audio content is a very cool opportunity. Sennheiser understands this and continues to develop the lineup of TWS headphones with noise reduction. We have tested the new Sennheiser CX Plus True Wireless model and will now share our emotions.
Sennheiser CX Plus True Wireless is a new and affordable active noise canceling model in the brand’s catalog.
Complete set and design Sennheiser CX Plus True Wireless
The complete set of the gadget: headphones, charging case, USB-C wire, replaceable ear pads and documentation. All this is securely packed in a box, which is made in the recognizable colors of the brand – white and blue.
We review the CX Plus True Wireless in black, and there is also a variant in white. The body of the case is made of matte plastic, which is very tactilely pleasant. Feels like it is close to soft-touch materials.
The Sennheiser logo is placed on the top of the case cover, and the charging port is on the back. There is a small status LED on the front surface. The case fits easily into your pocket and does not take up much space. Outwardly, it resembles a small “chest” – a fresh and unusual shape for the TWS headphone segment.
We should also note the sound of the closing case. It makes a noble clap, which feels somewhat similar to the sound of a closing case from a musical instrument. The lid opens and closes with a light yet pleasant effort. The mechanism gives an impression of reliable – nothing creaks or plays.
Inside the case, the earbuds are secured with magnetic holders, so they do not fall out even if you turn it over.
Sennheiser CX Plus True Wireless are made in a rather unusual form factor that visually distinguishes them from competitors. This is an advantage for headphones as it gives them their own visual style. They have a glossy surface on which the brand’s logo is placed.
I liked the complete ear pads – they sit comfortably in my ears. It should be noted right away that the headphones are protected from moisture according to the IPX4 standard, which means that they don’t care about walking in the rain and playing sports.
The aforementioned glossy surfaces house touch controls. They recognize different types of taps, including familiar playback control gestures such as single and double tap, and short and long hold. Thus, you can answer calls, switch tracks and call the voice assistant. Sennheiser CX Plus True Wireless are also equipped with special sensors that are responsible for automatically pausing playback when one earbud is removed from the ear.
Sennheiser CX Plus Application and functionality
To fully control all the functions of the headphones, you must install the proprietary Smart Control application from the App Store or Google Play . The program provides access to sound settings using an equalizer, as well as reassigning touch control parameters.
After the first connection, Sennheiser Smart Control prompts you to select the most suitable fit by rotating the headphones in the auricle. After that, the program will also remind you of the main functionality: quick reconnection to another device and customizable touch controls.
Literally immediately, a notification arrived about the availability of an update for the headphones. The download and installation took about 10 minutes. All this time Sennheiser CX Plus True Wireless must be connected to the smartphone and be next to it. Also, the application must be in active mode. The application interface is simple and concise – only the necessary settings and nothing more. The main screen displays the charge level, as well as the main functions, including:
- Acoustic transparency – allows you to hear ambient sounds and communicate with interlocutors without having to remove your headphones
- Equalizer – this section allows you to use presets, as well as adjust the frequency level manually using the line or sliders. You can save your own settings.
- Connections – a manager of connected devices that allows you to quickly switch between them.
The rest of the Sennheiser Smart Control features are hidden in the sandwich menu – a button with three stripes in the upper left corner of the main screen. Here you will find information about your headphones and application settings.
In the upper right corner there is a button for additional settings with a gear image. Additional parameters are collected here:
- Smart pause – Automatically pauses playback when one earbud is removed.
- Active noise suppression switch.
- Auto Answer Calls – allows you to receive incoming calls when the earbud is removed from the charging case.
- Automatic shutdown settings.
- Local Effect – Reflects the voice during a telephone conversation.
- Personalization of touch controls.
- Voiceover of messages.
Sennheiser CX Plus Sound and noise reduction
Now let’s get to the fun part. At first, in general terms, I liked the sound of the Sennheiser CX Plus True Wireless very much. The brand’s approach to the sound of its devices is well known to most users – it is an even frequency range without distortion, allowing music compositions to unfold as the author originally intended. Sennheiser CX Plus True Wireless is no exception in this regard.
The sound from the headphones is obtained in a volumetric manner without embellished frequencies. Thus, when switching from one genre to another, the sound does not get lost in an indistinct mess. The stage is quite wide, so all tracks in electronic and instrumental music are well “read”.
Separately, I would like to note the very clean high and middle frequencies. However, the bass is in order – they nicely fill the background and complement the sound. And if suddenly someone does not have enough of them, then you can always tweak it in the equalizer or use the Bass Boost preset.
Overall, the Sennheiser CX Plus True Wireless sounds equally good for all types of audio content: music, podcasts, and video tracks.
The active noise canceling system works efficiently and not aggressively. In other words, the hum of the street and other monotonous noises are cut off. At the same time, you do not feel pressure on the ear canals during prolonged use.
According to the manufacturer, the Sennheiser CX Plus True Wireless battery life is up to 24 hours with the charging case. For almost two weeks of testing, we can safely confirm this figure. It takes about 1.5 hours for the headphones to charge from 0 to 100 percent over the wire.
A status indicator on the case indicates the charge level. So, for example, green indicates a full charge, and red indicates the need to charge the gadget. During the charging process, the yellow light turns on.
A full charge of the headphones themselves lasts about 8 hours of playback. This figure varies slightly within 20 minutes depending on the environment. For example, if you use the headphones for a long time while walking in the cold, the battery life will be about 7 to 7.5 hours. In my opinion, this is more than enough, since I hardly use such long and continuous playback sessions.

In the catalog of the legendary brand with a recognizable sound, a model appeared in the middle price range with an active noise cancellation system – and this is cool. Sennheiser CX Plus True Wireless costs from 185 USD . Thus, they have every chance of becoming a New Year’s present for users who value the manufacturability of the gadget and the accuracy of the sound.
Among the advantages of headphones, I would like to point out clear sound with a flat frequency range, a comfortable fit and an effective active noise cancellation system. Also to all this you can add IPX4 protection and a decent margin of autonomy. In this case, an excellent value for money is obtained. Is this not the main thing when choosing a gift for yourself, family, friends or colleagues?
