Good Sound. Great Range - My wife and I have different ideas about what an appropriate volume for watching television is. She has a pair of JBL Bluetooth headphones and I have a pair of VOKALEN Hyper Pros. I like this device because you're free to use what you've got and aren't locked into a brand of headphones you don't like. I split the AUX out of the TV to go to our soundbar and to this device so we can use both. Setup was really as easy as putting the headphones in pairing mode and pressing the button on the device; They find each other easily. The audio is clean and stable and I was a little surprised at the range. I didn't think it would go as far as it does. And the device is smaller than I expected too so it's easy to find a place to put it. Review: Great blue tooth amp - The unit works great right out of the box. No setup. Just plugged in the optical out from the TV and then searched for blue tooth device and connected immediately. ## Features - 【WORKS WITH OPTICAL & AUX TVs】This Bluetooth transmitter works with TVs that have Optical (TOSLINK) or 3.5mm AUX audio output, sending TV audio wirelessly to Bluetooth headphones or speakers for private TV listening. - 【WATCH TV WITH TWO HEADPHONES】Connect two Bluetooth headphones simultaneously from one transmitter and enjoy TV together. Supports aptX-Adaptive for high-quality audio and reduced delay with compatible headphones. - 【BUILT-IN VOLUME CONTROL】Adjust volume directly on the transmitter using the built-in volume control buttons, especially helpful when TV remote volume control is unavailable due to fixed audio output. - 【NOT FOR HDMI-ONLY TVs】Not compatible with TVs that have HDMI-only audio output, as this product works via Optical or AUX connections only. - 【LIMITATION / IMPORTANT NOTES】When using Optical output, the TV audio setting must be set to PCM. Bluetooth headphones must be placed into pairing mode to connect successfully ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B0DK8TC1WJ | | Additional Features | 1. aptX-Adaptive Support; 2.

Great Range *by K***N on July 7, 2026* My wife and I have different ideas about what an appropriate volume for watching television is. She has a pair of JBL Bluetooth headphones and I have a pair of VOKALEN Hyper Pros. I like this device because you're free to use what you've got and aren't locked into a brand of headphones you don't like. I split the AUX out of the TV to go to our soundbar and to this device so we can use both. Setup was really as easy as putting the headphones in pairing mode and pressing the button on the device; They find each other easily.

And the device is smaller than I expected too so it's easy to find a place to put it. ### ⭐⭐⭐⭐⭐ Great blue tooth amp *by H***N on August 25, 2026* The unit works great right out of the box. No setup. Just plugged in the optical out from the TV and then searched for blue tooth device and connected immediately. ### ⭐ 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.jp/products/675977990-audikast-3-bluetooth-tv-transmitter-for-2-headphones-aptx-adaptive](https://www.desertcart.jp/products/675977990-audikast-3-bluetooth-tv-transmitter-for-2-headphones-aptx-adaptive) --- *Product available on Desertcart Japan* *Store origin: JP* *Last updated: 2026-09-10*
