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. ## Customer Reviews ### ⭐⭐⭐⭐⭐ Works Great, seamless reconnect *by J***L on 20 October 2024* Had a dodgy Bluetooth connection between my top end Samsung 2023 TV and my Sony headphones and Samsung ear buds which kept dropping out and loosing sync, this great little box has solved that, easy to setup, reconnects with no effort and has boosted volume levels so saves on the battery in the headphones / earbuds as you can have the volume on lower on these, great device would recommend for sure. ### ⭐⭐⭐⭐⭐ Perfect! Exactly as described and easy to setup. Would 100% recommend *by A***R on 2 June 2024* The past few weeks I've bought cheaper versions of this type of product mainly something where you just plug a usb stick into your TV. The problem with those type of products is they can work but with wireless headphones like mine, there is no way to turn up the sounds so you end up with an output where it's incredibly quiet or inaudible if you like eating crisps whilst watching a film like me.I've just unpacked this, watched the tutorial and within 10 minutes I've set this up and got it working. I have Bluetooth Sony earbuds and testing the sound volume ans it's perfect. Thank you much for creating a product that actually works and for solving my frustration with this. Would 100% recommend this product and well worth the investment. The fact that you have to plug this into a power source is further suggestion that it has been designed correctly for maximum output.Don't waste your money with other cheaper product variations. Buy this! ### ⭐⭐⭐⭐ Using Apple AirPods to provide enhanced hearing aid from TV *by A***L on 26 January 2020* Don’t normally write reviews; been seeking a unit to work with Apple AirPods as the most comfortable ‘headphones’ to use. Amazed at how this was a plug and go with instant pairing and working over the 3.2 mm audio cable. Sound quality as food as tv speakers or inexpensive sound bar. No background noise when on mains or from TV. If the sound bar is used simultaneous (for my wife whilst I use AirPods to compensate for my slight deafness) there is a very very slight latency echo which strangely enhances the ease of listening to speech. The volume control on TV adjusts volume to AirPods whilst the sound bar connected by optical cord has its own separate volume control so works independently. Interesting plug the audio link into a reasonable quality Denon audio unit and that works and with good quality sound. I suspect others are looking for a solution to allow use of Apple AirPods to provide enhanced hearing aid and this review is for them rather than those seeking perfect quality audio. ## Frequently Bought Together - Avantree Audikast Plus - Bluetooth Audio Transmitter for TV with USB, Optical & AUX Audio Output Port, Wireless Bluetooth Adapter for TV Headphones, Support 100ft Long Range, Dual Link, Volume Control - Amazon Basics Toslink Digital Optical Audio Cable, Multi-Channel, for Audio System, Sound Bar, Home Theatre, Gold-Plated Connectors, 6 Foot, Black - BlueRigger Digital Optical Audio Splitter 1x2 (1 in 2 Out Unidirectional Toslink Splitter, Support LPCM2.0, Dolby Digital, DTS 5.1)- for Home Theatre, Xbox, DVD, TV, Receiver, Sound Bar --- ## 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/167096390-avantree-audikast-plus](https://www.desertcart.jp/products/167096390-avantree-audikast-plus) --- *Product available on Desertcart Japan* *Store origin: JP* *Last updated: 2026-05-08*
