is this usb, or bluetooth?

A USB dongle goes into your computer, then the dongle communicates with the keyboard using a Microsoft wireless technology (not bluetooth).

It is neither. It has a small radio transceiver that you plug into your USB port. The keyboards communicate via Radio Frequency (but not Bluetooth) to the radio transceiver. The range is much less than bluetooth... about 6-8 feet or so.

Wireless via a USB dongle. The dongle stores neatly under the battery cover, and is instantly recognized when the USB dongle is plugged in.

Yes, it's Bluetooth. (And with Amazon, a return is never a problem should it not--but it will.)

It connects to a computer. It should be noted however that the USB is not OTG

Yes, it is Bluetooth capatible, available SD card slot and only one USB 3.0 input.

Yes, it is bluetooth. I guess they include it for devices that are not blue tooth, like some older MP3 players. I hope this helps.

I can't confirm the Bluetooth setting, but it does stay on USB or FM settings. It will stay on the USB even if I remove the drive so I imagine the Bluetooth would stay on as well.

No, it is either Bluetooth or audio headphone jack inputs. The USB port is for charging only.

It has a USB port, but that is for a power cord. I don't think the unit has any computer components within it and is solely dependent on either a Bluetooth signal from a device or data through the USB cable.

It is a bluetooth device, but it does not come with a bluetooth dongle, at least not that I was aware of. It did come with a Logitech wireless usb dongle.

The USB Charging cable, when plugged into a PC, will deliver audio. You also have the Audio cable that you can plugin if you dont want to use bluetooth

It's there. The usb cable acts as an antenna, and then there are buttons on the top to switch on the radio. You have just hold down the Volume button I think and hold till it changes to Radio mode. YES,,,, there is a RADIO. It's not just Bluetooth, I have it and use it.

It's bluetooth, but fairly cheap. So yes, but I don't highly recommend it. It kept losing connection and having issues on our iMac.

You'll need a Bluetooth dongle if your PC or laptop � has no build in Bluetooth. The rest is plug and play!
