KAIY Bluetooth 5.3 Receiver for Home Stereo, Optical Low Latency & HD Music Audio Bluetooth to RCA Adapter for Stereo/Speakers/Wired Speakers/Home Audio Music Streaming Stereo System, Support AUX/USB

This is an update to an earlier review that I gave only 1 star that KAIY C.S. responded to that was wonderful. After working with them and Amazon Digital Device Tech Support, I edited my rating to 5 stars and rewrote this review. Buy this BT receiver if you have the need for one.Initially I had an issue after pairing and connecting this BT receiver to a new Echo Show 5 Gen 3 (latest version as of this date) that kept dropping the BT connection when streaming music to all my Echo and FireTV stick devices in what is called a multi-room speaker group. I had no problem with the BT connection when streaming just from the Echo Show, my Laptop, or phone thru this BT receiver to a stereo receiver in the same room connected by a 3.5mm cable. I only had a problem just when I streamed music (several different services) to my Amazon multi-room speaker group, my stereo speakers that were used with this receiver would stop and sound would instead come only out of the Echo Show Gen 3.I provided KAIY and Amazon's Digital Device Tech Support with detailed info to help resolve this problem and spent a lot of time on the phone specifically with Amazon but still had no resolution with the BT connection dropping. Amazon's Echo Tech Support escalated this problem to their Back-End / Advanced Support group who provided this info basically stating the cause of the problem is not with this BT Receiver and another that I bought, but with Amazon in using Wi-Fi to connect their devices and export sound out to a BT Speaker(s). Here is what Amazon wrote for me that others reading this can learn from if faced with the same issue I had:"If the Echo device is connected to a Bluetooth speaker and simultaneously connected to Multi Room Music, then if the customer requests music to play from Multi Room Music using the name of the group, then it will disconnect from bluetooth device and play music from Multi Room Music devices only. This is an expected behavior by design."So the problem was not with this BT receiver dropping the BT connection, it was the Echo Show 5 gen 3, my first Echo device that does not have a 3.5mm port built-in that I then attach a 3.5mm cable to either a stereo receiver or soundbar for much better sound then the tiny mono echo device speaker. With older generation Echo Shows (gen 3) and Echo Dots (gen 4 and gen 3), almost all of them have a 3.5mm cable attached to use other speakers. Since this Echo Show Gen 3 did not have a 3.5mm port, I had to use BT and they suggested this particular BT receiver with others being displayed in the search results.I don't understand why Amazon would eliminate the 3.5mm port since they already know without it the only way to connect better speakers to their Echo devices for output is with BT, however their devices can't participate in any Amazon multi-room speaker group - awful. All prior versions of the Echo Show Gen 3 and Echo Dot Gen 5, which I own have the 3.5mm port in them. AMAZON, BRING BACK PLEASE IN FUTURE GENERATIONS OF YOUR ECHO DEVICES, THE 3.5MM PORT SO WE CAN USE THEM WITH BETTER SPEAKER SYSTEMS IN A MULTI-ROOM SPEAKER GROUP. Most Cell phone models no longer have 3.5mm ports so phones can be slimmer and more water proof, these are not concerns with Echo devices.With a 3.5mm port and cable to an external sound device, besides streaming music to Echo and FireTV's in large speaker groups, with any Echo device, I can speak verbal commands that effect all or any specific echo device(s) such as lower volume to level 2 on Den Dot. Stop playing music only on LR Dot, pause playing music to the group home, resume playing music to the group home, mute sound on Den Echo...etc All of these effect better sounding speakers basically connected to each Echo device, something customers of your Echo devices can't do without the 3.5mm port on the back.

Im genuinely suprised at how quick this device establishes connection, there is less connection time with this device then with my big name brand bluetooth earbuds.. Plenty of cords come, the rca to 3.5 auxiliary cord could be a bit longer but for 20 bucks the whole kit is well worth the money, transmits sound well for my needs but I'm no audiophile if your looking for studio quality obviously this aint for you its 20 bucks

Works very well

Im shocked... This little guy is amazing the audio sounds great, the optical is about flawless. It has an almost unreasonably long BT range, and just WANTS to pair up to your device. A lot of items like this need to be tryed repeatedly to get it to pair...not this one. It jusr fi3s exactly ehat is supposed to and ut fies it exstreamly well. Awesome product, don't let the look fool you because this is a gem.

Great right out of the box! I plugged it in to my newly repaired and refurbished 1959 Normende Elektra radio. Pairing was easy and the sound is better than expected. This unit comes with all kinds of connecters (RCA, 3.5mm, optical) and one very, very short USB C power cord.Would I buy it again? Yes I would. This receiver is worth its price.

Bluetooth works as you would expect it to. No issues there. My biggest issue is with the USB media player portion since is the whole reason I bought this specific model .I have an old radio with an aux port. I wanted to load up a USB stick with MP3 files and just have it play in a loop. I loaded up some music in one folder, and some old radio commercials in another. I hoped it would just randomly shuffle through all the files and play music with occasional breaks for funny commercials.I loaded up the stick and plugged it in and after a brief search of the drive is started playing commercials…one after the other. Never ever tried to play the music.I took the files out of the folders and moved them all to the root of the USB stick. Same results…in fact it picked right up. Where it left off in the middle of a commercial. Frustrated, I removed the stick deleted all the commercials…only music on the stick now. I plugged the stick back in, it resumed playing the commercials (that I just deleted from the USB stick)! what the???Multiple reboots of the device had no impact. It must be caching the data somewhere??? I don’t know.What I do know is that the media play portion is absolutely terrible.I never did find an ability to shuffle the tracks. That’s ok. I can live with that. What I can’t live with is its inability to update.I would also mention that (as others have said) the instructions that came with it is so tiny, it’s impossible to read. Plan on taking a picture of it with your phone and blowing up the picture to read the largely unhelpful instructions.-—-UPDATE——The vendor has been absolutely awesome with this issue! A lot of troubleshooting later, I discovered the reasons for my issues.1. The playing of deleted tracks seems to be the device not recognizing the deleted flag on the file and playing it anyway. A full format of the drive resolved this.2. It turned out that the media player doesn’t recognize mono mp3 files. The commercials were in stereo and the music was in mono so that explained why some files would not play and others would.In the end, I’m guessing that the mono issue won’t impact many people, and formatting the drive when changing files, while a nuisance, isn’t the end of the world.Support for this was so good! They sent me a second unit thinking the first was defective. They were in constant contact with me and really went the extra mile to help me out. Honestly, they were great to deal with!So yes, this didn’t work for my very specific use case, but odds are it will work just fine for yours…especially if your primarily use is Bluetooth, because I had absolutely no issues there.
