Bluetooth headphones say “connected,” but there is no sound
A Bluetooth connection does not necessarily mean your phone or computer is sending audio to the headphones. Check the source device’s audio output before resetting the headset. Sennheiser’s Bluetooth no-sound guidance, dated 14 April 2026, recommends checking power, range, output selection, volume, and connection with another device.

- Make sure the headphones have charge and are connected to the device you intend to use.
- Open the phone or computer’s sound settings and select the Sennheiser headphones as the audio output. A connected status alone does not confirm that audio is routed there.
- Raise the volume on both the source device and the headphones, then try audio from another app.
- Test with a second phone or computer. If sound works there, focus on the first device’s settings or Bluetooth connection.
- If the problem remains, remove the headphones from the source device’s saved Bluetooth list and pair them again using the model’s instructions. Use a factory reset only as a last resort because you will need to set up the pairing again.
When the Smart Control app connects but audio does not
Some Sennheiser products use Bluetooth Classic for audio and Bluetooth LE for the Smart Control app. The app-oriented connection is not a substitute for regular audio pairing. Complete the headphones’ audio pairing with the phone first, then open the app if needed. Button sequences and pairing steps vary by model; for example, MOMENTUM 5 Wireless has its own troubleshooting instructions, which should not be applied to other headphones.
Do these 3 things before closing this tab:

First find out whether the fault follows the headphones or stays with the audio source. Sennheiser’s wired one-sided-audio guide, dated 13 July 2026, recommends checking connections and the source jack, then testing with another audio device.
#1 Best Overall
- Read Before You Buy — No Video Output: These adapters support charging and USB 2.0 data transfer, but cannot transmit video signals. Except for standard USB webcams (which use USB data only), they are not compatible with HDMI/DisplayPort cables, video-capable USB-C hubs, or docking stations with video output.
- Convert USB-A Ports to USB-C: Designed to connect USB-C earphones, cables, flash drives, card readers, and other USB-C accessories to standard USB-A ports. Plug-and-play with no drivers or software required.
- Aluminum Alloy Housing: Built with a sturdy aluminum alloy shell that aids in heat dissipation and protects against daily wear and scratches. Designed to maintain a stable and secure connection.
- Compact & Travel-Friendly: The ultra-compact design allows the adapter to stay plugged into your device without blocking adjacent ports or adding bulk, reducing wear and tear on your original USB ports.
- 12-Month Warranty: Backed by a 12-month manufacturer warranty for peace of mind. Designed to meet strict quality control standards for reliable everyday performance.
- Unplug and firmly reseat the cable at both ends. On many Sennheiser models with a cable that connects to one earcup, the plug twists to lock; an unsecured connection can cause one-sided or intermittent sound.
- Check the audio source’s jack for dust or lint. A phone case can also stop a plug from going fully into the jack.
- Try another source device. If the problem disappears, the original device or its jack may be at fault.
- If your model has a removable cable and tests point to that cable or its connection, check the exact model and connector before choosing a replacement. Sennheiser does not establish a single cable as compatible with every model.
If the problem persists and testing points to the headphones, Sennheiser’s support guidance says to contact Sennheiser for further assistance.
Bluetooth headphones will not charge, or one earbud will not power on
Charging checks depend on whether you have Bluetooth over-ear headphones or true-wireless earbuds. Do not assume that every product uses the same cable or follows the same charging procedure.

Bluetooth over-ear headphones
Check the model manual to confirm the charging cable type. Sennheiser says current models use USB-C while older models may use Micro USB; its Bluetooth headphone charging guidance, dated 14 April 2026, advises trying another USB port or cable if there is no charging indicator. A cable that fits physically is not, by itself, confirmation that it is the right one for your model.
True-wireless earbuds
If one earbud will not power on, check that both earbuds sit correctly in the case and that ear tips or fins are not obstructing the charging contacts. Clean the contacts and allow time for charging. Follow the product-specific steps in Sennheiser’s True Wireless Charge Troubleshooting guide, dated 14 July 2026. Its indicator checks and service advice apply to true-wireless products, not over-ear headphones.

When to stop troubleshooting
If the appropriate checks for your model do not resolve the problem, contact Sennheiser support or service rather than opening a sealed battery product or trying a generic battery replacement. Sennheiser’s MOMENTUM 5 Wireless support page, in the regional version reviewed on 26 June 2026, lists model-specific spare parts; availability can change, so check the current page for that product. For another model, use its own support hub and manual.
