I had the products VicTsing Bluetooth A2DP stereo music 19275 Jukebar Bluetooth Speaker + Pure² bought Dongle Transmitter Adapter for 3.5 mm audio ... + 2 pieces Trust PT-810 jack audio receiver Bluetooth together. The reach of my TV to the boxes broke off a distance of 3 to 4 meters from already. Also, I could with the transmitter (Vic Tsing) couple only one speaker, not two ... because I had bought two. I have returned every 3 or 4 products (namely as 2 speakers). All together was my no solution to connect the television in the kitchen with wireless speakers and listen to music stations in adjoining rooms or on the next facing terrace. Unfortunately, I also had to find an audio delay: in normal TV mode, movies ... it's rather annoying ... and I wanted it, of course, use. Whether it was rather on the transmitter, or at least on the box, I did not find out. The Jukebar speakers had a good sound for the price ... but the range was too low as mentioned with max. 4 meters. I have all returned and had quickly get my money. Best service! Keep it up! Thanks.
