NEW DELHI: Sennheiser ACCENTUM Wireless can carry audio and microphone input through its USB cable, as well as charge over that connection. The official manual tells owners to disconnect Bluetooth, attach the headphones to a Mac, PC or mobile device, and select ACCENTUM as the playback and recording device in the host's sound settings.

Start with the exact headphone name
This procedure concerns ACCENTUM Wireless, the around-ear model identified as ACAEBT in its instruction manual. Keep the full name when searching for help. ACCENTUM is also a family label, so a result for another member of the range is not enough to establish the connection options of the pair on your desk.
For an Indian user switching between a work computer and a personal phone, the USB option is useful because it gives a concrete alternative setup to check. The question becomes whether the computer has selected the headphone as its sound device. It is a narrower problem to investigate than changing several wireless settings and a meeting application's preferences at the same time.
Connect and choose the output
Follow the manual's sequence: disconnect existing Bluetooth connections, connect the supplied USB cable between headphones and host, then open the host's sound preferences or control panel. Select ACCENTUM as the default playback device and start familiar audio. The manual says charging happens automatically through the USB connection.
Check the selected output before turning the volume up repeatedly. If a laptop continues playing through its own speakers, the first useful observation is where the sound is going. Selecting the correct device is part of Sennheiser's procedure, rather than an optional finishing touch. Keep the initial test simple enough that you can tell which step altered the result.
For a computer shared by several people, make a note of the previous default output before changing it. This is practical housekeeping: the next person may want the built-in speakers. Once you have confirmed playback through ACCENTUM, return to the application you actually intend to use and check that its sound reaches the same destination.
Select the microphone separately
The manual also permits ACCENTUM as the default recording device. Choose it as input if you want to use the headphone microphone, then make a short test recording or use the preview in your calling application. Listen back before joining a meeting. Hearing music through the headphones does not, by itself, tell you which microphone an application is recording.
This is particularly relevant to a home office arrangement with an external webcam or another connected microphone. Decide which input you intend to use, then check the selection explicitly. You do not need to change a working webcam microphone merely because the headphones are connected; the aim is to choose knowingly and avoid discovering the wrong input during a call.
When returning to wireless use, check the selected sound destination again. Keeping the USB setup and the Bluetooth setup as separate checks makes your own troubleshooting notes easier to follow.
Keep wireless battery claims in their proper place
The India product page advertises up to 50 hours of battery playtime, hybrid active noise cancellation and a Transparency Mode. It also lists Bass Boost, Podcast mode and a five-band equaliser. Those describe listening options and the wireless endurance proposition. They are separate from the manual's USB routing instructions and do not replace checking the host's input and output.
For a sensible first comparison, use a familiar track with your preferred sound settings and keep the volume comfortable. Judge whether the wired workflow suits your desk rather than expecting a particular improvement in sound. This guide has verified the available connection method; it has not measured an audible difference between USB and Bluetooth or tested every computer and phone.
Consider the cable's physical route as well. Leave enough slack to move naturally in your chair and keep the connection away from the edge of the desk. A wired working arrangement should be convenient enough that you can remove the headphones without pulling the host device. That practical detail matters more than adding an unsupported sound-quality claim to a feature checklist.
