It is nice that it comes with usb adapter and blue tooth adapter so that you can use it with your computer or with audio equipment that is not bluetooth compatable. I use it with my reciever and can listen to my dvds or tv shows. Could be more comfortable.

This product works well, and I was satisfied with all its features except one. The connection between the earpiece and the headband broke after about 15 hours of use, despite not having been subjected to rough treatment. I didn't try to work through Koss because I figured it was easier to repair it myself. I repaired it with glue reinforced by nylon fishing line. If you buy this product, remember that the hinge where the earpiece folds is too weak.

I received the Koss Cobalt Wireless Bluetooth Headphones today. Charged them up for about 3 hours before the first use and then began testing them. They came with a 3.5mm transmitter and a usb transmitter - both which work very well.

First thought was that they looked and felt nicer than I was expecting. They are plastic but compared to other less expensive headphones, they seem somewhat sturdy. It's my first behind-the-head set of headphones so fitting them for the first time was a little strange but once I got used to them they were very comfortable.

They paired up very easily to both the 3.5mm transmitter, USB dongle and my Android cell phone.

Sound quality was pretty good, at least for a $50 set of headphones with Bluetooth.
Good highs and even the lows were pretty decent.

They are not noise cancelling, but do a fairly good job of blocking out noise when the music is on. They have a built in volume control which is really nice.

Overall, for the price and quality, I would have given them 5 stars except for a couple of minor gripes.

They don't come with a carry case and they also don't have a direct 3.5mm connection in the event that you would like to connect the headset directly to the source. That would have been a nice addition.

Again, a pretty decent set of headphones for the price.

I probably had higher expectations for headphones. I have several headphones Koss Porta Pro and I am extremely satisfied. So I expected that Cobalt will be something similar.
Unfortunately, the sound is much worse (I had to boost bass by more than 10dB), I think that there are different drivers. The method of hanging on the ear is not much convenient, headphones are hard and my ears start to hurt after some time.
With my phone (Nokia), headphones disconnect after I press PAUSE and I have to turn bluetooth on the phone completely off and on in order to reconnect.
