Does the speaker come with a power adapter or is it just plugged into the usb and speaker ports?
Hello there! The speaker does not include a power adapter, it has a USB power cord and a 3.5mm stereo audio cable. If you need to connect to other power sources, you can use a 5V/1A USB power adapter. We have equipped an additional Type C adapter.
When you have headphones jacked in, are you able to adjust the volume with the knob?
Yes. You can use the knob to adjust the volume or the computer to adjust the volume.
How long are your speaker cords?
The length of the computer speaker is 59.05 inches (approximately 150 centimeters). The USB power cord and audio cable are kept separate, which allows for more flexible usage.
When I plug headphones in to the speaker does it mute the speakers?
Yes!!! And it allows you to say goodbye to plugging the earphones into the bulky case, causing the problem that the earphone cable is not long enough.
Can this be used for a laptop?
Yes, of course.This speaker can be used for any device as long as it equiped with a USB(Type-C) jack and 3.5mm aux jack.
