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: Easy to set up wireless/bluetooth speakers without cables running all around! - Easy setup. I bought this for the following reasons. Bought a pair of echo dot pair for my TV and to integrate this two speakers, I bought this bluetooth transmitter. Tested it. Works great. the power supply for the transmitter can come directly from the USB port in the TV and it acts as wireless speakers without Alexa (whose sound quality is tremendous) and making this whole thing value for money!

## Features

- [CHECK TV PORTS BEFORE PURCHASE] Works only with TVs that have optical (TOSLINK) or 3.5mm audio OUT ports. Not compatible with HDMI / ARC / eARC ports, TVs that only have HDMI, or with audio–in / headphone–in jacks.
- [EASY SETUP – PLEASE FOLLOW TV SETTINGS] Connect the transmitter to your TV’s optical or 3.5mm audio OUT port and power it via USB, then put your Bluetooth headphones into pairing mode. Make sure your TV audio output is set to “External Speakers” / “Optical” / “Headphones” in the sound menu. If you don’t hear any sound, follow the troubleshooting steps in the included Quick Start guide or our online video.
- [SET TV AUDIO FORMAT TO PCM] For optical connections, please set your TV’s digital audio output to PCM / Stereo in the sound settings. Surround formats such as Dolby Digital / DTS are not supported and will result in no audio.
- [LOW LATENCY WITH COMPATIBLE HEADPHONES] When used with headphones that support aptX Adaptive or aptX Low Latency (e.g. Avantree Aria Me, Audition 3), you’ll enjoy TV audio that is virtually in sync with the picture. With standard Bluetooth headphones, a small delay may be noticeable – this is normal for regular Bluetooth.
- [DUAL LINK] Pair your Audikast 3 with two pairs of headphones simultaneously and share your enjoyment with your loved one.
- [POWERED BY QUALCOMM] With its advanced Qualcomm chipset, the Audikast 3 delivers clearer sound, stable connections, and improved battery life for connected devices – all backed by Avantree's 20+ years of Bluetooth expertise.

### ⭐⭐⭐⭐ 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.
