With the CX True Wireless, Sennheiser launches wireless earphones that have what it takes to be a bestseller. After all, they sound better than most competitors at a relatively low price and are real endurance runners. Actually, only ANC is missing, but not really either.
For ntv.de, the Sennheiser Momentum True Wireless 2 are still the wireless earphones that the competition has to measure up to in terms of sound. However, buyers have to dig deep into their pockets for the outstanding sound experience; you can’t get the high-end earbuds for less than 230. That’s why the manufacturer launched the CX 400BT True Wireless last fall, which offered the same sound with fewer extras. However, with a price of 200 euros, the earphones were still not really cheap and many users preferred to reach for cheaper competitors. This could change with the successors, which are simply called CX True Wireless and start at around 130 euros.
Visually, Sennheiser has not changed much. The logo on the plain charging case is no longer shiny silver and the outer surface of the earphones is now matte. In addition, the LED to indicate the charging status has moved from the back to the front of the box and there is no longer an extra button for pairing.
That something has changed technically can be seen, among other things, in the fact that the earphones now only have two charging pins each. However, the shape of the earpieces has remained the same, which is a good thing. Because they sit very comfortably and securely in the ear.
Excellent sound without ANC
The sound is unchanged good. The CX True Wireless are neutrally tuned in typical Sennheiser fashion, delivering rich bass, wide, well-defined mids and crystal-clear highs with plenty of detail. The stage is very wide for earphones. In addition, the excellent Smart Connect app offers presets and an extensive equalizer with various options to adjust the sound to personal taste.
The new CX earbuds do not feature active noise cancellation like the Momentum True Wireless 2. However, you hardly miss it, since the passive of the earphones is so strong that you would rather wish for a transparency mode to let the outside noise through in traffic. Unfortunately, they do not offer this function. Furthermore, Sennheiser once again omits sensors that automatically pause playback when you take a plug out of your ear.
Longer mileage and splash protection
Despite being priced lower than their predecessors, Sennheiser has incorporated key improvements. For example, the CX True Wireless are IPX4 protected from sweat and splashing water and offer a much longer runtime. The earphones last up to 9 hours and the carrying case has reserves for up to 18 hours. In addition, the CX True Wireless radio in Bluetooth 5.2 (aptX, AAC), although only one device can be connected at a time.
The controls remain unchanged via the large touch surfaces on the outer sides of the earphones. The competition can also take a leaf out of this book. Because you can really control everything, including the volume, via one, two or three taps as well as longer holding. The app also offers the option to customize the controls.
Top price-performance ratio
With their excellent sound, great endurance and now also splash protection, the Sennheiser Momentum True Wireless for 129 euros are currently the price-performance champion among wireless earphones. Users who primarily value the top sound can also buy the predecessors, which are now available for just under 115 Euros (~$115). The Google Pixel Buds 2 for 100 Euros are an interesting alternative for Android users.
