Therefore, it will stay on till it drains up all the remaining battery power. One full charge would provide max. 15 working hours.It means that you will have to make the pairing once again if you don't use TRONDBT-DUO X for over 15 hours or even less. Please also feel free to email us at support@etrond.com for any further help.Regards,TROND Customer Care **Q: If i have a usb charger and i plug it to this unit, will it always stay on?** A: As a transmitter or in the TX mode, it will always stay on if you use an external USB charger and plug it to TROND BT-DUO X.Regards,TROND Customer Care **Q: When paired with two speakers/headset, will the aptx LL protocol be active for both devices?** A: Hi, Steve,The codec will be downgraded to SBC instead of aptX LL when the transmitter pairs to two Bluetooth devices simultaneously. This has been pre-defined by the CSR 8670 chipset, and there's nothing that we could do about it.Regards,TROND Customer Care **Q: Can i connect my hk portable speaker to my non-bluetooth tv as well as my dish hopper with sling so i can use the speaker as the only tv sound source?** A: It depends on whether your TV has this type of audio setting, and allows you to select the digital optical port (or the 3.5mm headphone jack, depending on which audio OUT port you use to connect TROND BT-DUO X to your TV) as the only audio output channel. If any other question, please feel free to email us at support@etrond.com for the further help.

I had a very specific use case for it. I wanted to rebroadcast my sound output to 6 different Bose Soundtouch wireless speakers. And it's wonderful for that.Here were the issues:- Bose Soundtouch devices will not rebroadcast through the aux port on the device, only bluetooth connections. It's limitation of Bose Soundtouch devices.- I wanted only sound to be picked off, therefore transmitted.- I have optical audio ports on the TVs.- I have 6 Bose Soundtouch devices to connect all at once because I wanted to be able to listen to a show, news, music, sports, while doing other things around the house and even outside.- I wanted to be able to easily disconnect the TV audio and play it through a normal sound system when the delay (1 to 2 seconds) from the sound rebroadcast was not acceptable when actually watching the TV.- I wanted the bluetooth disconnect to not effect other wireless usage of the 6 Soundtouch speakers when not using Bluetooth audio feed.With the help of this device, I have met all my above criterion. I am able to use the wireless broadcast of sound through the speakers located in various places around the house and outside. I am able to use the optical audio cable that comes with Trond bluetooth transmitter and connect it to the TV. TV audio also still works normally. I am then able to hit the button on top of the bluetooth transmitter and connect to the Bose speakers to rebroadcast. I am able to easily turn it back off, holding the button on top for about a second, and use the Bose system normally.Super simple and functional. Reconnecting bluetooth has not been a problem, ever. No more than a button press has been required. I have never found a good use of the optical audio port on my flat screens until now. My stereo is too old for that sort of connection.I rarely use the battery so I can't comment on that. I leave the device plugged in all the time. Also, I have moved it about 25 ft away and the sound was never interrupted. I suspect your mileage may vary on the distance given interference conditions in your own house. But I'm quite pleased with this performance for a bluetooth device. ## Frequently Bought Together - TROND Bluetooth Transmitter Receiver, Bluetooth Adapter for TV/PC, Wireless Transmitter for Speakers and Home Stereo, AptX Low Latency for Both TX and RX, Pair with 2 Devices Simultaneously - TROND Bluetooth 5.2 Transmitter Receiver, 2 in 1 Bluetooth Adapter for TV to Airpods or Wireless Headphones, Low Latency, 3.5mm Transmitter Audio Adapter for Airplane Gym Equipment Home Stereo - TROND Bluetooth 5.0 Transmitter Receiver, Bluetooth Adapter for TV, 2 in 1 Wireless Audio Transmitter for PC MP3 Gym Airplane, Receiver for Speakers Headphones Boat Car --- ## Why Shop on Desertcart? - πŸ›’ **Trusted by 1.3+ Million Shoppers** β€” Serving international shoppers since 2016 - 🌍 **Shop Globally** β€” Access 737+ million products across 21 categories - πŸ’° **No Hidden Fees** β€” All customs, duties, and taxes included in the price - πŸ”„ **15-Day Free Returns** β€” Hassle-free returns (30 days for PRO members) - πŸ”’ **Secure Payments** β€” Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** β€” Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.pl/products/38368949-bluetooth-digital-optical-adapter](https://www.desertcart.pl/products/38368949-bluetooth-digital-optical-adapter) --- *Product available on Desertcart Poland* *Store origin: PL* *Last updated: 2026-05-16*
