Review: A little jewel! - This is a great little Bluetooth transmitter!! It has low latency, handles two Bluetooth devices at once, and has a handy volume boost control. Sound quality is superb. When powered via USB from my TV, it turns on with the TV, in the pairing mode! Pairing my headphones is a snap! Works every time within seconds. I highly recommend this product. All of this is true for me. It pairs with my headphones in seconds! Much easier to use than the built in Bluetooth on my LG TV!
Review: I Gave It Some Patience. And It Worked Great With My Bose Headphones - This unit will work with a set of Bose Bluetooth headphones. They work perfectly, in fact! I originally bought this unit very concerned that it would not work with my mother’s Bose Quiet Comfort 35 II. Unfortunately, she doesn’t have Bluetooth on her television. The headphones worked great on a fire cube, but I decided to go back to cable. I wasn’t sure if this would also work with my TIVO box, but because the television is wall-mounted, I thought it would be easier, as it was obvious, I would have an easier time plugging up the wires. I noticed that my TIVO box has two USB out ports, so I plugged the included USB power cord right into one of these, and the unit powered up perfectly. I then plugged up the optical cable into the back of the TIVO box as well. Because I was using an HDMI cable for both picture and sound, I didn’t need to use the TIVO optical port, it was just not being used. It was a perfect opportunity to use the included optical cable, that came with the unit. I was so pleased because all this meant that now I did not have to go behind the TV at all. The first thing that I did was to hold down the power button on my mother’s Bose headphones, in order to clear all previous pairings. I wanted to make sure there were no conflicts, besides I was only going to use these headphones with this device. Now everything was going perfectly, except for the paring of the Bose headphones. Others have complained that Bose headphones will not pear at all with this device, however, patience is the key here. I too had some difficulty and was convinced that the Bose headphones would not properly pair with the device. I was only more patient because I was used to paring the Bose headphones with my mother’s desertcart Fire Cube. It used to give me trouble when attempting to pair the Cube and the Bose headphones together. Sometimes, I would have to try several times to get them to work together. I had to wait and wait for them to finally connect. Sometimes I started over and even restarted the Cube box again to make them both work together. However, my efforts always paid off, for once they pared, they worked wonderfully. This experience taught me to be patient, and to not be too impatient when trying to pare my Bose headphones to this Avantree unit. It took a long time, and I almost gave up, when suddenly my Bose headphones informed me that a connection had been made. I was so very pleased. Now I know I can use the unit on my television as well as my TIVO BOLT. Perfect, not only that, but I can also watch TV while my 93-year-old mother continues to listen to her headphones. Because the television is connected to the TIVO BOX with an HDMI cable, the sound is being sent to both the headphones through the optical cable, and the television speakers through the HDMI cable. So, if my mom wants to watch television alone, all she has to do is turn down the volume on her television and listen quietly on her BOSE headphones with the Avantree unit. If I come into the room and want to watch Television with her, all she has to do is turn up the regular volume on her Television, so I can listen too. This was so easy to install, I was very surprised at how easy it was to get it going, all I needed was a little patience. Our house is once again quiet, for this is a great little unit. In conclusion, this unit will work with Bose Bluetooth, just be patient. This will work with TIVO, but I only mentioned TIVO in case you also have a TIVO box as I do. This is an advantage, but you don’t need a TIVO box at all to make this work, I am sure it will work perfectly on your television at home.

## Questions & Answers

**Q: What range can I expect?**
A: Audikast reaches up to 100ft / 30m in open space, but the range may vary due to obstacles, interference, headphone reception, and the number of devices connected to the transmitter.

**Q: Can I have audio through my TV’s speakers and wireless headphones at the same time?**
A: It depends on whether your TV can output audio to two devices simultaneously. If not, we offer products for simultaneous TV audio on an external speaker and Bluetooth headphones.

**Q: I have a wall-mounted TV and cannot reach the audio-out ports in the back. Will this work with an HDMI-connected TV box?**
A: This transmitter doesn’t have an HDMI port. However, by using the Audikast with our Avantree Hax05, an HDMI audio extractor, you can easily resolve this issue.

**Q: What devices are compatible with the Avantree Audikast Plus Bluetooth 5.3 Audio Transmitter?**
A: The Avantree Audikast Plus is compatible with most Bluetooth headphones, speakers, and soundbars supporting aptX, aptX Low Latency, aptX-Adaptive, or SBC codecs. It can connect to two devices, but performance may vary by brand.

### ⭐⭐⭐⭐ Great little product, but may interfere with your 2.4Ghz
*by A***. on November 13, 2025*

Item was smaller than I expected. Was very easy to set up using the intructions (e-manual). Works very well and no issues with lag. Sound quality was good (for bluetooth). Tested with a pair of Sennheiser Momentum 4 headphones. Note that sound quality will also dependent other factors like the music source , bluetooth version and codec supported by your headphones. The reason for 4 stars and not 5 is that the Bluetooth signal appears to interfere quite badly with the 2.4Ghz wifi band. My TV kept dropping its wifi connection and connection speed also suffered. This may not be an issue if your tv's wifi supports higher frequencies (e.g. 5Ghz) I placed it a bit further from the tv, but the supplied optical cable is a bit short. If you encounter similar issues, may be worth considering getting a longer optical cable to have the unit further from the tv. I also turn the device off when I'm not using it.
