Well I took a shot with these because of price and good reviews:

There wasn't any mention of compatability with the kfhd but folks noted it worked with the Nexus 7 so I'd least I'd be able to use it with the latter.
Well they work after trying yesterday with the kfhd. I'd say a pretty good deal given the cost. Range is about 30 feet, they are comfortable and not bulky!
