Question: I am looking for a headset to use on the computer but I do not have bluetooth capability.  Does this come with a USB adapter?
Document: After using the road king 400,found it easy to use , great product .I would recommend it to everybody looking for Bluetooth headset
A lot of truckers use the BlueParrot which looks like a $5 dollar headset from 1980 with universal remote control buttons on the side. This RoadKing is more up to date. I was worried about the sound amplification as a lot of Bluetooth headsets are quiet, but this one is so loud that I have to turn the volume down a little.
There was a quirk initially when pairing to both my phone and computer and I had to disconnect my computer and then reconnect the PC in order for the phone to begin working. Now both devices are working at the same time (knock on wood!) which was IMPOSSIBLE with the latest Blue Parrot headset. I will see if there is a firmware update for the Blue Parrot that might help.
The RoadKing RK400 Noise Canceling Bluetooth Wireless Headset is awesome! I would recommend it as a great purchase. The wireless feature is wonderful.
It is not worth the hundred dollars you will pay at a truck stop but it is worth $60+ you pay online.I would gladly pay $200 for great headset but in the meantime this will work and I'm not likely to run into the washer as I do with my smaller Bluetooth earpieces.
I think it's a design flaw in the headset. I don't push any buttons on the headset or phone it just goes on mute. Pushing the mute button on and off on the phone doesn't fix it either. Neither does turning Bluetooth off and on on the phone call screen. You must disconnect the headset and reconnect and then things are fine.
I have had my set for four months. Read the directions and it is very easy to use. The customer service is excellent! I highly recommend the road king brand. I had the on/off button quit working and they sent me a new headset.
Unfortunately one time, and for the call for which I bought this headset, it did not work. It did not answer the call. When I did get the call answered I could not use the headset or the phone to talk to the person. I could hear them. They could not hear me. Since then I answer using the only the phone and not the button on the headset.
The Road King  RK400 works well when it works but it does have some flaws. When I'm traveling I cannot hear calls on those Bluetooth headsets, so I decided to give this full headset and boom microphone a try. I bought it specifically because I had an important meeting coming up and needed to be able to hear the conversation while on the road.My first challenge was that it took hours to get the RK400 to pair with my standard phone.
I prefer for that earpad to sit right above my ear.For a person with an average or heaven forbid, small head, this headset is huge and will not fit snugly. It may be floppy on your head but you will hear and be heard clearly.The second problem are the voice prompts. They are so garbled that you can't understand them. Many Bluetooth headsets have voice prompts and I can understand them all clearly. Not with the RK400. Power Off sounds like Ummphh Arrgh Ummmph!
Answer: It does not... You can fine a usb Bluetooth dongle for your computer on amazon
