Cowin E7 Troubleshooting

When trying to connect using bluetooth the device will not pair with your mobile device.

Disconnect the back-up audio cable and disconnect the USB charging cable. Having headphones connected might be preventing the Bluetooth from connecting. Attempt to connect again without any other cables connected to the headphones.

On your mobile device, disable the Bluetooth feature and then re-enable. Delete your E7 from the Bluetooth listing on your device. Move your mobile device closer to the headphones and away from any interference or obstructions. Attempt to connect with another mobile device.

If the Bluetooth signal is weak, out of range, or if there is interference the connection may fail, or the sound will cut in and out.

Please move away from any other devices or obstructions. This includes barriers such as walls and any other wireless transmitters, Bluetooth headphones, and/or devices that are distanced less than 15 meters. You may need to move your mobile device closer to the headphones. Try to connect again.

Recharge the battery and check if the network signal is OK (whether the player is buffering). Having low battery power will reduce the strength of your Bluetooth connection.

If the headphones and the Bluetooth device are not compatible via consistent issues with the headphones, your version of Bluetooth might be outdated. Make sure you have downloaded the most recent software update for your mobile device or have updated your drivers to the latest update on your computer.

When attempting to play audio through the headphones there is little to no sound.

Power on the headphones. If the headphones do not power on, charge the battery. Increase the volume on your headphones, your mobile device, and music source. If you are unable to adjust the volume on the headphones, or the volume button is stuck, you may need to replace the volume button.

Make sure you are connected to the correct device by checking your Bluetooth on your phone and checking connected devices. Make sure the device is within proximity of the headphones. Move your mobile device closer to the headphones and away from any interference or obstructions. Use a different music source and try to connect a different mobile device. The problem might not be the headphones but the device that is trying to connect.

The headphones are having issues with basic functions such as staying on, connecting via Bluetooth, producing audible sound.

First secure the ends of the USB charging cable. If this doesn’t work, try another charging source as it might be just a problem with the electrical outlet. If your headphones have been exposed to high or low temperatures, let the headphones return to room temperature and try charging again. If these methods do not work, you may need to replace the battery.

When the headphones play audio and noise canceling is enabled, there is little to no difference in sound quality.

Make sure that the noise canceling function is turned on. Slide the noise canceling function button to the “NC” position. The noise canceling button is located on the bottom of the right ear piece.

Adjust the ear cushions to fit your ears. If the ear cushions are loose, reset the ear cushions. If there is damage to the ear cushions allowing noise to escape, you may need to replace them.

(Info point) The noise canceling function is effective in low frequency ranges such as airplanes, trains, offices, near air-conditioning, and is not as effective for higher frequencies, such as human voices.
