How To Pair Sennheiser Headphones? (All Headphone Models)

Although earbuds are great, I prefer headphones, especially when going out for a jog or doing any task that requires recurrent moving. That is why I got the Momentum 4 headphones from Sennheiser since they were the best model from the brand, according to the salesperson. 

The headphones work great so far, which intrigued me to learn about other wireless headphones from the brand. In the process, I noted that coming by information on how to pair them to different devices was scarce. 

Hence this article will describe how you can get the headphones in pairing mode and, therefore, easily connect them to other devices like your phone. 

Key Takeaways

Pairing Sennheiser Headphones

There are a few models of Sennheiser wireless over-ear headphones, and they follow slightly varying pairing procedures. Below are steps for getting these headphones into pairing mode:

MOMENTUM 4

• These headphones will automatically power on when you pick them up and put them on. However, you can manually power them on by pressing the multifunction button for three seconds. The button is on the right earcup close to the LEDs.
• The LED will flash white three times to show that the headphones have powered on. Note that when only one LED flashes white three times, the headphones are paired to a device through Bluetooth.
• When you power the headphones on for the first time, they go into pairing mode automatically. However, if they have been paired to a source device before and it is in range with Bluetooth enabled, they will pair automatically.
• You can manually get the headphones in pairing mode by pressing and holding the multifunction button for five seconds while the headphones are powered off. 

To enable pairing mode on Sennheiser Momentum 4, press and hold the multifunction button until you see the LEDs flashing white in a continuous sequence.

• You will hear a tone as they power on, and the LED will start flashing white in a continuous sequence while simultaneously playing a distinct tone.
• From here, you can go to your source device, enable Bluetooth settings, and select MOMENTUM 4 from the list of available devices. If prompted to enter a PIN, use four zeros (0000).

• Once pairing is successful, a ‘Pairing Successful’ audio prompt will play, followed by another prompt ‘Connected.’ One LED will flash white three times to indicate the headphones are connected to a device. 
• If you leave the headphones in pairing mode for two minutes without connecting them to a device, they will go into standby mode, and you will have to repeat the pairing process.
• Also, note that the headphones can remember up to six previously connected devices and can actively connect to two devices simultaneously. However, they can only play audio from one device at a time.
• You will require the Sennheiser smart control app to shuffle between previously connected devices, provided those devices are within Bluetooth range and have it active.

The steps to pair these headphones to source devices via Bluetooth are as follows:

• Power on the headphones and get them into pairing mode by pressing the on/off button for four seconds.
• The button is located on the right earcup next to the LED.
• The headphones’ LED will start flashing red and blue to show they are in pairing mode.

To initiate pairing mode, press the ON/OFF/Bluetooth button on the right cup, next to the LED. Keep it pressed until the LED starts flashing red and blue.

• You can now go to the source device, enable Bluetooth, and search for ‘HD 450BT.’
• Once successfully paired, the LED will flash blue three times, and a ‘connected’ audio prompt will play through the headphones.
• If you use the headphones for the first time and have never been connected to a source device, you can power them on by pressing the on/off button for two seconds.
• The headphones will then play a ‘power on’ audio prompt to show they have turned on and will see the LED flash blue three times.
• Then the LED will flash red and blue to indicate that the pairing mode is enabled. 
• On the other hand, should the headphones have been connected to a source device before, and the source device is within Bluetooth range and has Bluetooth active, the earphones will pair to that device. You will hear a ‘connected’ audio prompt instead of the ‘power on’ prompt, and the LED will flash blue three times.
• If the headphones are left in pairing mode for five minutes without connecting to a device, they will automatically go into standby mode, and you will have to restart the pairing process. 
• The headphones can remember up to eight previously connected devices but can only actively connect to two simultaneously. 
• You can access the headphone’s additional features by downloading the Sennheiser smart control app that is available for Android and iOS devices.
