Q&A

Q: Why can't headphone pair with my mobile phone?

A: Please check if your headphone is in pairing mode or re-connection mode. Check if the Bluetooth search function of your BT device is turned on. If all done, then go to the Bluetooth menu of your Bluetooth device, delete/ignore the headphone Bluetooth pairing name "NC35". After that, you can try to reconnect Bluetooth according to the "Easy Pairing" steps.

Q: Why can't headphone turn on?

A: Please double-check the battery status of your headphone.

Q: Can I replace the battery in the headphone?

A: No, you cannot. The headphone uses a built-in non-detachable Li-Polymer battery that cannot be replaced.

Q: Can I use the headphone while driving?

A: For your safety, we strongly recommend that you do not use the headphone while driving to avoid distraction.

Q: Why does the headphone sometimes disconnects with a Bluetooth device within 10 meters?

A: Please check if there are any metal materials or obstacles within a relatively close range or your surroundings that might be interfering with the Bluetooth connection. This may happen because Bluetooth is a radio technology which is sensitive to objects between the headphone and other devices.

Q: Why can't I hear any sound from my computer or mobile phone?

A: Please check if the output channel of your computer supports the A2DP profile. Also, check the volume settings on your headphone and computer/mobile phone.

Q: Why am I unable to use the headphone to control the volume of a track playing on an APP on my mobile phone?

A: Due to configurations of different application software, the headphone may not be completely compatible with some APPs.

Q: What do I do if Bluetooth cannot close or open?

A: Please reset the Bluetooth function of the headphone by inserting an audio cable into the headphone audio port, then removing it. Before re-connecting, kindly remember to delete/ignore the headphone Bluetooth pairing name "NC35" on your mobile phone.

Q: Why does Bluetooth turn off when I connect an audio cable?

A: This is one of our special features. When users insert an audio cable into the headphone audio port, all Bluetooth feature buttons stop working and Bluetooth turns off. But, Bluetooth will be available again when the audio cable is moved.

Q: Why can't I turn the headphone on/off?

A: Please note that ANC and Bluetooth are indicated by the same LED indicator light (but with different light colors), with a green light for ANC and a blue light for Bluetooth. If you need to turn Bluetooth on/off, you can turn off ANC firstly in case you get confused by the color lights. But you will become very familiar with the light color meanings after using it a few times because it is simple and easy.

Q: Why does audio quality become poor on Windows PC?

A: Some customers have mentioned poor audio quality on Windows PC. Please note that there are "Headset" and "Headphone" modes you can toggle by changing your output device. Selecting "Headphone Mode" will drastically improve the audio quality. "Headset Mode" is designed for highly compressed VOIP calls, etc. That's not the fault of the headphone product; that's just the limitation of that protocol. If you are in "Headphone Mode", the audio quality is fantastic.
