I connected it to my old model Sony 3+1 home theatre system. I needed a bluetooth adapter to connect that old school sound system to my brand new Nebula projector and i ordered that device. I connected it to the audio output of the bluray player, which also works as the amfi of the system, and it synchronised easily and successfully. No disharmony or discordance between the sound and image. It works really on time. Sound quality is satisfactory however there is a deep noise which is audible when nothing is being played. Once you turn on the sound you don't hear it. Which is quite acceptable for a 11 USD device. Review: Basic, but reliable, audio puck - Bluetooth can cut out, but it's rare. Hard to know if it's the rcvr or something with my phone. It does have a friendly voice saying "connected" right before playback. Otherwise, I can say it faithfully connects for hours on end. For best results, don't move the phone around too much during playback. Set it on a table or countertop. I have an older phone used just for music, which sits 2m away on a charger. If there's a problem, it's usually bc the playlist ended or a power spike caused a reboot. This one is best suited for HiFi audio systems using end-to-end RCA cables (wht/red). Mine is hooked up to the input for "CD". Tried "TAPE", but the signal had too little voltage. Any input marked "AUX" should also work well. The single button controls it all; long push to flash the light red/blue (pairing), which also shuts it off after a long press. Once connected, the button acts as play/pause, but no skip function. ## Features - AUX 3.5mm/RCA audio receiver : There are 3.5mm or RCA output port for home old stereo speakers/wired headphones and more to connect mobile phones, computers, tablets to play music via Bluetooth.

My only complaint is that you have to depress and hold the on/off button for about 4 seconds. It should be one touch for on and off. When it is playing, the button does serve as pause/play, but I think that would rarely be used by anyone. Just make it one touch for on/off. ## Frequently Bought Together - UGREEN Bluetooth AUX Adapter Built-in Battery, Support Dual Pairs Bluetooth 5.3 Receiver for Old Stereo, 3.5mm/ RCA Dual Channel for Home Stereo Speakers - UGREEN Bluetooth 5.2 Transmitter Receiver, Dual Pair Wireless Adapter for Airpods, Headphones, Speakers, TV, PC, MP3, Gym - UGREEN 5.4 Aux Bluetooth Adapter, Noise Cancelling 3.5mm AUX Bluetooth Car Adapter, Wireless Audio Receiver for Home Stereo/Wired Speaker, 15H Battery Life --- ## 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.tn/products/37622930-bluetooth-aux-adapter-built-in-battery-support-dual-pairs-bluetooth](https://www.desertcart.tn/products/37622930-bluetooth-aux-adapter-built-in-battery-support-dual-pairs-bluetooth) --- *Product available on Desertcart Tunisia* *Store origin: TN* *Last updated: 2026-06-05*
