"The positive aspects of the Strauss and Wagner SW-TW401 are the deep bass if that is what you like, plus the small form factor of the case and earbuds that are light and comfortable."
"The sound quality shames most other earphones at this price, and it’s built like a tank. Furthermore, the slim fit means you can easily forget you’re wearing them once the music starts playing."
"The bass-heavy EQ drives dance music to a new level and is a solid choice if you enjoy a heavy bass. You’ll also appreciate the compact, easy-to-carry case."
Available Replacement Parts:
Please note that we are unable to provide a replacement charging case for the TW401, whether through purchase or warranty. Each set of earbuds are calibrated to their respective case, so there's no way to make sure that the new case will match your specific earbuds.
Troubleshooting:
The TW401 earphones are not made to withstand heavy sweating. They do not have a water resistance rating, and therefore we do not recommend using them for sports/fitness/gym. Please see our for your exercise needs.
Issues Charging:
- Upon receiving the package, the case needs to be charged at least ONE hour and then earbuds need to be charged a minimum of TWO hours before using them
-
Make sure the tiny piece of plastic on the yellow contacts on both earbuds is removed before charging them in the case
- If the original charging cable is lost or damaged, you will need to replace it with a hi-res cable. A low-quality cable will cause charging problems for the case
- Lithium battery needs to get charged every 3 months while not using. Some batteries might incur problems after a long time of not getting charged
Reset connection to device:
- Begin with both earbuds in the charging case
- Disconnect Bluetooth on your device
- Delete the earphones from your device's memorized Bluetooth device list
- Take both earbuds out at the same time
- Connect back to Bluetooth
Reset earbuds:
- Take both earbuds out of the case at the same time
- Click both earbuds 5 times (this is the reset method)
- Put both earbuds back into the charging case (re-activating)
- Take out both earbuds again (both earbuds flashing blue lights means pairing, until one light goes off, which means they paired successfully)
Reset both connection and earbuds [for pairing issues, music not playing, etc]:
- Make sure the charging case and earbuds are fully charged using the original charging cable
- Begin with both earbuds in the charging case
- Disconnect Bluetooth on your device
- Delete the earphones from your device's memorized Bluetooth device list
- Take both earbuds out of the case at the same time
- Click both earbuds 5 times (this is the reset method)
- Put both earbuds back into the charging case (re-activating)
- Take out both earbuds again (both earbuds flashing blue lights means pairing, until one light goes off, which means they paired successfully)
- Connect back to Bluetooth
Pairing issues [if only one side is pairing]:
- Begin with both earbuds in the charging case
- Open the lid and note which of the earbuds is blinking
- Press and hold the top button of the earbud that is not blinking until it starts blinking too
- Remove both earbuds from the case and they should both begin pairing with the device
Contact issues [earbuds not firmly contacting with charging case]:
- Place earbuds into charging case
- Close the lid
- As long as the lid can be closed properly, earbuds will get charged (charging case indicator light on = charging)
Other:
- The buttons do NOT work unless the earbuds are connected to a device
- Make sure the charging case has enough power to charge both earbuds
- Make sure the charging pin is cleaned with alcohol
- Make sure the golden connect port and the golden charge pin is clean
