The History of Sennheiser
Sennheiser made its humble beginning in 1945 and was founded by Fritz Sennheiser as a venture which in today's time is known as a 'start-up'. It all began in a farmhouse near Hanover. After realising the potential of highly growing business opportunities, applying the expertise and experience of his scientific career he started the company to meet the rising demand of measuring devices and microphones. The story of innovation which started then continues till date. Even today if you visit Sennheiser headquarters for listening sessions, product support or to get a factory visit you can sense their passion and unending energy for excellence and innovation.

The Sennheiser Vision
The one thing that connects Sennheiser employees and associates around the world is its vision. A vision of developing never like before sound experiences that would prove instrumental in shaping the future of the audio world. Sennheiser has always been a very customer-centric audio company. Sennheiser also understands that the first step for any music listener is to trust the audio equipment and that is precisely why they are focused on delivering reliable audio products. At heart, Sennheiser is a team of audio enthusiasts who employ technology to make you reach new dimensions of the audio world for an unforgettable sound experience.

Its smart features make life and listening effortless. Transparent Hearing lets you focus on external sounds when desired, while customizable touchpads ensure effortless control of audio, calls and voice assistant access.
The Sennheiser CX Plus True Wireless has been designed for all day use, with a sleek ergonomic design for fatigue-free all day wearing and up to 24 hours playback with on the go charging. Thanks to IPX4 rated splash resistance you can keep on enjoying the Sennheiser CX Plus True Wireless wherever you go.
Thanks to the addition of ANC (Active Noise Cancellation), you can enjoy the exceptional sound without any distraction. Furthermore, Transparent Hearing lets you decide to hear your surroundings when desired. Smart Pause stops and resumes music automatically when earbuds are taken out of your ear.
The Sennheiser CX Plus True Wireless supports a wide range of Bluetooth audio codecs and is upgraded with aptX Adaptive, which delivers low-latency, robust and high-resolution Bluetooth wireless audio.
The design of the Sennheiser CX Plus True Wireless has been further refined to ensure optimal user comfort. The improved ergonomics and refined design make it even easier to achieve the best possible fit.
While blocking noise is made easy, it is also just simple to hear ambient sounds when needed thanks to the Transparent Hearing feature, which makes it possible to hear outside sounds or have conversations in comfort without even needing to remove the earbuds.
Qualcomm® aptX™ Adaptive audio supports low-latency, robust and high-resolution Bluetooth wireless audio.
The Sennheiser CX Plus True Wireless does not feature wireless charging. However, due to the 24 hours total playback time, charging of the Sennheiser CX Plus True Wireless is only rarely necessary. Furthermore, with just 10 minutes of charging you can get additional 1 hour playback time.
Additionally, you can check for the current firmware release status in the Smart Control app's settings.
You can reset the earbuds to the factory default settings using the Smart Control app in the settings menu.
Using the Smart Control app is the easiest way to perform a factory reset. Alternatively, you can reset the earbuds to the factory default settings by the following steps:
•Deactivating Bluetooth at your smartphone to disconnecting your Sennheiser CX Plus True Wireless.
•Take only one earbud out of the charging case, keep the other earbud inside the charging case.
•On the earbud outside of charging case, hold the touch control for at least 10 seconds.
•As soon as the earbud LED starts alternating green/red, release the touch control (within 2 seconds).
•After releasing the touch control, the earbud LED continues to alternate green/red.
•Place the earbud back into the charging case.
•Keep the charging case lid open!
•The earbuds are now getting again synced with each other, what takes approx. 20 seconds.
•Successful factory reset and peer pairing is indicated by 3x green/red alternating charging case LED.
Additionally, make sure the earbuds are inserted into your ears correctly. Increase the volume on your Bluetooth device and on the earbuds by pressing on the right earbud's touch pad until you hear the voice prompt "Volume max".
The Sennheiser CX Plus True Wireless has integrated a single-mic feed-forward ANC system per earbud side. This technology enables ANC without negative impact on sound performance (i.e. no additional noise floor is introduced by the ANC system), nor discomfort (i.e. no ear pressure is introduced by ANC system). In case you experience only limited ANC performance, consider that ANC technology can only reduce ambient noise in low frequency range <1 kHz, e.g. engine sounds. The Sennheiser CX Plus True Wireless' excellent passive noise isolation additionally reduced significantly ambient noise in higher frequency ranges.
To achieve best possible sound isolation and ANC performance, it is important to choose the ear adapters that best fits your ears.
