Bests & Worsts Reviews from Amazon

I have tried 4 headsets/headphones with the unit, following syncing directions carefully. I am an advanced tech user, with more than 30 years experience with high tech. The BLueSense Transmitter does not pair with anything I have tried. The company support phone number has no technical assistance and an email to them has gone unanswered. I will be returning the item. Update: went back to first headphones tried and started again. It connected this time, so now I can listen to my Kindle with this unit. The other three still will not connect. Sound is very clear and clean. Update 2: Tried it with two more older headsets and the GOgroove would not pair with them. Got a response from the company but it simply repeats the directions that came with it. I also tried reverse pairing with all the headsets and it did not help. Update 3: It does pair with bluetooth speakers since it paired with two I had, the easiest was the Creative D90. What I have found in my extensive testing is that it does not pair with anything that normally requires a pairing code, such as cellphone earpieces. It does pair with headsets made for mp3 players and bluetooth speakers, but with some you have to reverse the pairing order.... first on, second on, etc. It should not be advertised as pairing with just about anything.
