It works very well. Easy connection to the optical port on the TV and the headphones picked up immediately. Sound quality for watching TV is good. No lag. ### ⭐⭐⭐⭐⭐ Good product & assistance from company was great. *by A***C on July 24, 2026* I purchased from Amazon a Audikast 3 wireless audio transmitter by Avantree to use with tv. Two people can pair headphones to this transmitter. Distance from tv is great. Easy setup but was able to reach out to Advantree with a few questions. Spoke with the Advantree representative who was very tech savy her name was Riza. ### ⭐ Awful Experience, Unable to use, nor get tech support! *by R***B on February 28, 2025* No instruction manual. Confusing Label on product blocking display. Awful tech support that on phone requires ZENdesk registration. Why should I want to have to enter credentials , just to access an instruction manual that should have been included with my payment for the product?!?!?!?!?! Their online chat is NOT active, and after providing name and email, THEN you are told to wait for reply! NO! That is not how customers should be treated. The actual tech support is useless.. It fails to reply to questions already asked, and what is most unusual for tech support - the emailed replies, offer no reference or thread to previous questions or communications, making any follow up unavoidably stressful and difficult ! What is worse, is that their tech support replies, repeatedly ignored, my comments. They finally insisted that their responses must have landed in spam. Well, I checked, and they did not! So tech support could not even communicate effectively about their communication failure! Auracast is an emerging technology that soon will be wildly popular. So manufacturers are rushing to claim compatibility. It is expected to be widespread in most public places allowing visitors to hear, via their ear pods, or hearing aids, what is muted for those otherwise, not interested. It will clarify sound for hearing impaired hearing aid users, and can offer multiple sound tracks, selected by the listener. In homes it can, and this should be active and possible right now, for multiple listeners whether it be in headphones, ear pods, or hearing aids, to the same source - a tv, computer, or other streaming source. I was not able to connect anything to this. Not able to find instructions that actually worked. Amazon Tech Support, at multiple levels, was not able to help. Avantree's website instructions were useless. ALL BAD. I gave this one star, but really it is just a big ZERO to be returned! ## Frequently Bought Together - Avantree Audikast 3 - Bluetooth 5.3 Transmitter for TV Audio with aptX Adaptive, Compatible with Optical & AUX Output, Dual Headphone Connection, 100ft Range - Amazon Basics Toslink Digital Optical Audio Cable, Multi-Channel, for Audio System, Sound Bar, Home Theatre, Gold-Plated Connectors, 6 Foot, Black - J-Tech Digital Optical Splitter 1 in 3 out for TV, Toslink Splitter 1x3 SPDIF Audio Splitter 1:1 Transmission Support LPCM2.0, DTS, Dolby Digital --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.sk/products/675977990-avantree-audikast-3-bluetooth-tv-transmitter-for-2-headphones](https://www.desertcart.sk/products/675977990-avantree-audikast-3-bluetooth-tv-transmitter-for-2-headphones) --- *Product available on Desertcart Slovakia* *Store origin: SK* *Last updated: 2026-08-19*
