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.

Cheap and EffectiveI recently bought a 4K TV because my 9-year-old 1080p set had started displaying “mouse tracks” across the screen—some driver or connection had clearly become intermittent. The missing pixels would come and go, but it was obvious that my old 65" flatscreen was on its last legs.Interesting side note: the old TV cost me $1,020 back in 2016, while the new 65" 4K model cost just $349! I figured I’d better buy one now in case tariffs push prices higher—even though this was a Korean brand, it was actually assembled in Mexico.One catch: the new TV had no audio outputs! And I wanted to keep using my existing high-end soundbar and subwoofer setup.First, I tried an HDMI eARC audio extractor—but it didn’t work.Then I bought THIS Bluetooth-based adapter.Success right out of the box.Simple to pair with the new TV.It includes 3.5mm-to-RCA outputs, but I only needed the optical SPDIF output, which matched how I had connected my soundbar to the old TV.Now I’m enjoying excellent sound with my “cheap” 4K TV—whose built-in speakers are, predictably, as underwhelming as most low-cost sets—thanks to this little gadget.Would recommend. Would buy again.

good

Got this to upgrade an older version, easy setup and visible status, it was had to tell when the old one was in pairing mode or even on. Sound quality is good, all the cables you might need (no ac adaptor though, uses standard 5v)

I bought this product to add Bluetooth functionality to my existing HiFi Audio Amplifier, but the AUX output of the KAIY Bluetooth receiver never worked.This is an example that the Quality Assurance at these minor Chinese manufacturers is generally very poor because the company - and others like them - seems quite happy to ship faulty units.Thankfully the L/R RCA outputs did work, so I did manage to add Bluetooth to my sound system, but the audio quality could have been better. Given that the unit is not expensive, I suppose it's a case of getting what you pay forOne annoying feature of the unit is that it "shouts" at full volume over my amplifier's loudspeakers that a Bluetooth connection is missing when you are 10 seconds too slow at switching on the Bluetooth transmission on your smart phone. I hope that this "feature" is removed from their subsequent models, because the unit's flashing "BT" display is more than adequate to indicate that a Bluetooth connection still needs to be established.It would also be nice if the unit would remember it's last output volume setting after it has been switched off.Given that the unit's AUX output never worked is the main reason why I will not buy anything from this company again. They have to take Quality Assurance seriously or they will lose customers.

I have an older Sony component stereo system that sounds great but doesn't have Bluetooth. I hooked this device up in about three minutes and it works beautifully. The audio is crystal clear. I'm probably going to purchase a second one to set up at my girlfriend's house.
