I wanted a solution for streaming music. This product fit the bill perfectly. There are some with a mic, but that could conflict with the car factory Bluetooth. Also, I have wired it internally from the cigarette lighter port. So the adapter gets powered when the car is turned on and powered off when the car is turned off. Caution: this unit is 5V and most cigarette lighter ports are 12V. So, I have a cigarette lighter to USB adapter that is used to power this Bluetooth adapter. I have paired multiple phones. The adapter connects to the last connected phone. If it is a different phone, you can go to the phone Bluetooth settings and initiate the connection. This is fine for me. Sometimes there is a hiss in the speakers at low volumes or if the Bluetooth is paired but not playing anything. This is not the limitation of the Bluetooth, but, ground loop noise. I have not found it to be an issue. There are products available to address this on desertcart as well as other places. I have not measured the power consumption but expect that it will be low power based on The Bluetooth 5.1 spec. When I start the car, the phone is paired to the car’s factory Bluetooth for voice calls and this unit for streaming audio automatically. I am happy with this product. Hopefully, the unit quality holds up, which only time can tell. Will post updates in a few months. Review: Server Solution for Bluetooth and more - Server solution to gain Bluetooth capability, use in conjunction with a USB audio adapter. Will use 2 USB ports (2.0). The USB Audio adapter provides audio output, this adapter plugs into the audio adapter and a USB Port for power and converts audio to Bluetooth output. Works great! So many people complain that they can't get Bluetooth on Windows Server and this is a nice work around for cheap. Should work fine on older TV's using the headphone jack, I've used other brands for that but haven't tried this one as I bought it specifically for the server. ## Features - 1.

The aux. output works fine, but sound quality using the aux. out of the adapter with my Hi-Fi audio system is not all that great. Optical or digital I/O typically produces much higher sound quality which was the main reason for choosing this device. ## Frequently Bought Together - Isobel Bluetooth 5.0 Transmitter Receiver (Optical, 3.5mm AUX, RCA), Low Latency Wireless Audio Adapter Bluetooth AUX Adapter for TV PC Car/Home Stereo System up to 2 AirPods Wireless Headphones - JBL Tune 510BT - Bluetooth headphones with up to 40 hours battery, microphone for call, foldable and comfortable, Android and iOs compatible (Blue) - TOSLINK Cable – 10 ft – Optical Audio Cable/Fiber Optic Cable - Designed in Germany - 24K Gold-Plated connectors, Metal case, S/PDIF Cord for soundbars, amps, Xbox One or PS4 – by CableDirect --- ## 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.pt/products/232991761-isobel-bluetooth-5-0-transmitter-receiver-optical-3-5mm-aux](https://www.desertcart.pt/products/232991761-isobel-bluetooth-5-0-transmitter-receiver-optical-3-5mm-aux) --- *Product available on Desertcart Portugal* *Store origin: PT* *Last updated: 2026-04-23*
