Please include the test result when resorting for email support.

1.Does the computer you use with have 2 of 3.5mm jack?


Q: Can I use it with smartphone or tablet/iPad? 

A: No, the 3.5mm output connector of K667 is TRS plug and the mic itself need 5V power to work. It means that you can only hook it up with computer that has dedicated 3.5mm MIC jack.    


Q: Can I use it with speaker that has 3.5mm AUX jack or plug it into 6.5mm jack via an adapter? 

A: No, neither input jack mentioned above on speaker provides plug-in power supply. While K667 needs 5V power to work, so it will not perform at all even the size of input jack fits.  


Q: Why the the sound is so low, I can barely hear it? 

A: K667 is a analog microphone, which doesn't have built-in ADC (analog to digital converter). So it's all down to the computer internal sound card to do conversion. 

You can try cranking up computer input level to 80% and speak much closer to the mic at around 3 inches. And it still doesn't turn any better, consider getting a external sound card. Let it do the job of conversion and send digital signal to computer. You would be able to sound louder by the time.     


Q: I plugged it into the 3.5mm jack of my computer and it just didn't work? 

A: Most of the current computers, especially laptop and Apple computer(including Mac, iMac, Mac Mini) has only one 3.5mm input that combines mic jack and headphone jack. That means you need to plug in a microphone with TRRS to get it work on those computers. While K667 is TRS microphone.


Q: Is it possible to make it work on those computer with mic and headphone combo 3.5mm input jack? 

A: Yes. You're not really buying the wrong product, just a simple USB sound card will help fix the problem, which making this K667 a computer USB compatible mic.   


Q: My laptop has dedicated 3.5mm MIC jack, I plug the mic in but it still didn't work? 

A: Once you hook up K667, it will replace the original internal mic. So you won't see any notification to tell you the mic is ready to work. And in every application, you just need to set the built-in mic as default input, and you're good to use K667. 

Thus, what you could do now is to check if K667 replaces the internal mic. Right click speaker icon, choose "Recording Devices", check if the level meter of the built-in mic (usually listed as Realtek High Definition Audio or something like that) bounces when you speak to K667. If not, just contact us right away with your test info. If meter turns green and moves, just make sure this internal mic is the default setting in all application you're going to use. 

If you're using an Apple computer that also has two 3.5mm jacks and one of them is MIC input, but the mic still didn't work, it gets tricky to find out the reason. Because we can't tell if it's a defective problem. The best solution is to find another computer with 3.5mm MIC input to test out.
