They sent me a replacement super fast. So far the replacement is trucking along just fine. The one I originally bought that went completely dead must’ve been a one-off manufacturing defect. Hey, it happens to the best of companies. Battery life is much better this time around on my replacement device, sound quality is good-superb just like before. No pops or static or anything. Very clean. Range is excellent as well. Sometimes I’ll forget to disconnect my phone when I stop somewhere and get out with it to go into a store to pay for gas or something and I’ll come back into the car and the podcast/music will still be playing. As in it never lost the signal at an estimated 50-80ft plus range. Just my everyday use review. Not sure on its max range. It’s a good product for its price. And if there’s an issue customer service is prompt and dedicated. β€”β€”β€”β€”β€”β€”β€”β€”β€”β€”β€”β€”β€”β€”β€”β€”β€”β€”β€”β€”β€”β€” Sound quality was good. Battery life was meh. It would last I estimated 3-4 hours max before it needed to recharge. But I only had it just over a week of light use and it just wouldn’t turn on again one time. It died and went kaput. Spend your money on something else that’ll last you more than a week or two. Review: I bought this to use with the aux port in my vehicle in order to stream music and audio books from my phone. It has been surprisingly effective for my needs and I will be permanently mounting it on my dash. The battery life has been very good. I'm not sure how long it lasts because I haven't taken any long trips since it arrived but I have not run the battery down yet. I was skeptical initially because I have had terrible experiences with many other bluetooth devices but this one seems to be a great choice so far. I do recommended a shielded charging cable and possibly a shielded aux cable if you plan to charge it while listening because there is a noticeable hum with the cables it comes with. The price point is very good and even if you replace the cables you would still be at a great value. The sound quality is equal to or better than playing directly through the aux cable. Also wanted to mention it is very simple to use and pairs quickly without hassle. ## Features - manufacturer: Generic - Item Trademark: GENERIC - Item Weight: ounces, pounds, 0.02500, 0.4 - Item Category: Wireless Audio Adapter ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B075WSFTTV | | Best Sellers Rank | #163,097 in Electronics ( See Top 100 in Electronics ) #240 in Bluetooth Car Kits | | Item model number | Bluetooth Receiver SR03 | | Manufacturer | SONRU | | Product Dimensions | 2.3 x 2.3 x 0.8 cm; 82 g | ## Product Details - **Brand:** SONRU - **Connectivity technology:** AUX, Bluetooth - **Material:** Aluminum - **Power source:** Battery Powered - **Special features:** Microphone, Stereo ## Images ![SONRU Bluetooth 4.1 Receiver, Aux Mini Wireless Audio Adapter Portable Hands-Free Car Kits for 3.5mm Audio Devices, TV and Home/Car Stereo Music Streaming Sound System (Bluetooth 4.1,aptX,A2DP) - Image 1](https://m.media-amazon.com/images/I/61o3g5okQnL.jpg) ## Customer Reviews ### ⭐⭐⭐⭐⭐ Review *by P***R on 28 June 2021* Edit: Company was A++.

Easy to install, and came with double sided adhesive to install on the dash. You have the choice of plugging in the aux connection directly into the device or use a cable to be able to move put the device anywhere. The aux cable as well as the charging cable are nice and long. I strapped them up with a zip-tie to avoid dangling cable. My cellphone connects automatically to it when holding the button for a few seconds. Press once to mute or twice to call the last recent number. Sound quality is good during calls. Only downside is see at the moment. Phone call volume is all the way up, but I have to crank up the radio to hear. Once the call is done and the music comes back up, it is crazy loud and I quickly have to turn it back down. ## Frequently Bought Together - Bluetooth Aux Adapter for Car, SONRU Bluetooth 5.0 Receiver for Car,Wireless Audio Adapter Portable Hands-Free Car Kits with RCA AUX 3.5mm for Home/Car Stereo Music Streaming Sound System - (Upgraded Version) FM Transmitter Bluetooth, SONRU Bluetooth Car Adapter [PD 30W & QC3.0 18W], Wireless FM Radio Transmitter, Hands-Free Calling, Siri Google Assistant, TF Card - Bluetooth 5.3 FM Transmitter Car Adapter - SONRU Car Charger 54W [PD 36W & QC3.0 18W], Wireless FM Radio Transmitter [HiFi Treble & Bass Player], 5 Colors LED Backlit, Hands-Free Calling, U-Disk --- ## 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.es/products/344216401-sonru-bluetooth-4-1-receiver-aux-mini-wireless-audio-adapter](https://www.desertcart.es/products/344216401-sonru-bluetooth-4-1-receiver-aux-mini-wireless-audio-adapter) --- *Product available on Desertcart Spain* *Store origin: ES* *Last updated: 2026-05-18*
