I have two BOSE SoundLink on-ear headphones and needed a BT transmitter to watch TV with my husband. This transmitter is my third attempt to use a BT transmitter and it WORKS with no problems. The first two: TaoTronics BT Transmitter with TOSLINK optical cable failed because it only works with 3.5mm cable; The digital optical port just didn't work. My parents have the same model and they have the same problem with the optical port - it doesn't work. The ARCHEER with optical TOSLINK failed because it ran for five minutes and then had trouble pairing. Pairing two headsets at the same time has become impossible. The third try is awesome. The HDMI ARC connector on my LG OLED TV is used with a soundbar/speaker system with an additional optical output for audio. This is the port I use with the Avantree Oasis Plus transmitter. Straight out of the box, not a single problem. It connected within minutes and my BOSE SoundLink headphones paired instantly with no issues. I plugged in a second set of headphones with no problems either. While BOSE isn't recommended for use with this transmitter as it doesn't support aptX, I haven't experienced any latency issues using both headsets at the same time. Last night we watched programs in 4K and the transmitted audio was well synced with close-ups. I'm willing to order 2 pairs of Avantree low latency headphones *if* there is a latency issue, but that's just not necessary at the moment. (I see a review that has latency issues with BOSE SoundSport Free headphones, but I think this is an issue with this model of headphones as a software fix is coming out in July 2018 to fix SoundSport latency issues.) What you pairing expect two headsets: connect the first audio transmission kit. Then, when you connect the second device, the first device will be temporarily disconnected for a few seconds while the second device is pairing. Once the second pair is connected, you will get sound on the first pair again.
