How to Connect My Sennheiser Bluetooth Headphones to My MacBook Proby Daniel Barrows
Sennheiser produces a wide array of audio devices, including several lines of headphones designed for personal use. Among these are several wireless offerings that come equipped with Bluetooth technology, such as the MM450. These products are compatible with similarly-equipped computers, including Apple's professional line of portable computers known as the MacBook Pro. OS X, the operating system installed on these machines, features a setup assistant designed to assist in the process of connecting Bluetooth devices to the computer.
Open the cover located on the left earcup of the headphones. Connect one end of the charging cable to the socket installed in the earcup. Connect the remaining end of the cable to one of the USB ports located on the left side of the MacBook Pro. Allow the battery to charge for three hours before proceeding.
Disconnect the charging cable from the headphones and computer. Close the cover on the left earcup. Hold down the button installed in the center of the right earcup until the surrounding LED blinks red three times. Press the button again until the LED blinks blue and red in alternating order.
Click on the [Bluetooth](https://itstillworks.com/13579495/what-is-bluetooth) icon located on the left side of the computer's menu bar. Select the option labeled "Set Up Bluetooth Device." Select the headphones from the list of entries and follow the onscreen instructions; when prompted for a passcode, input "0000."
Check the LED on the right earcup; if the LED is blue, a connection has been established. Repeat steps one through three if the LED is blinking red. Put the headphones on and play a piece of audio to confirm that the device is working.
Locate the two buttons installed near the bottom edge of the right earcup. Press the left button if you wish to toggle the Bluetooth connection on and off. Press the right button if you wish to activate the "NoiseGard" feature. Press the buttons installed around the LED on the right earcup to adjust the playback volume.
