esinkin Wireless Audio Receiver for Music Streaming Sound System Works with Smart Phones, Tablets and Car, Wireless Adapter for Speakers

Good little adapter/receiver. This product worked great. We were looking to have a way to play music from across the room to an older receiver and this device worked perfectly.It has great range on connection, easily 50-75 feet. Installation couldn't have been easier and there's nothing to operate it. Great buy for the price and utility.

Every year I help run sound for a holiday party. I bring a small PA for the jazz combo and in between sets I play songs off of my phone via Spotify. I've always connected my phone to the PA mixer via an RCA/lightning adaptor cable, but that left me tethered to the mixer if I wanted to change songs manually as opposed to just letting the playlist play continuously while I mingle. Finally this year, I realized, duh, I should probably get a bluetooth transmitter so I can move around the party. (Yes, I am slow to pick up on things.) I reached out Sweetwater and told them I wanted to spend $40 and they suggested an item for $110 and then an item for $60. I looked on Amazon and found this device for $23. I ordered it and it arrived on time, but the PA was already packed and ready to go. With fingers crossed, I arrived at the party, set everything up and with 2 minutes before doors opened, I opened up the box, hoping it would be easy, I even forgot my glasses so couldn't read any small print! I quickly plugged in the small AC adaptor to the device. I remembered reading that the logo was the bluetooth pairing button so I pressed it, it lit up and my phone paired within just a few seconds. I then took the RCA cable plugged it into the PA with the other end - the round 1/8" (3.5 mm) male end - going into an obvious and easy to spot female end on the esinkin device. Turned up the volume on the phone and the PA a little louder than before, and it was on!The entire set up time from opening up the box to hearing sound, all without looking at instructions, was about 90 seconds. The sound quality was totally great for this price point and I walked about 75 feet away to go to the bathroom without any loss or breaking up before I realized I better leave my phone inside the room.So, long story short, this device was a fantastic lifesaver! Gonna buy one for my car too!

The Esinkin Bluetooth device was incredibly easy to install. While it can be powered using a separate wall outlet, I opted to use the electrical plug on the back of my Yamaha receiver. This way, the Bluetooth device powers on and off along with the receiver, which is very convenient.Pairing with phones and iPads was simple and seamless. Switching between devices is also straightforward: the current device playing music needs to stop playback and close the app, allowing another device to take over by starting its music app.It’s hard to believe this tiny Bluetooth device has replaced my massive 300-CD player. Its footprint is just a fraction of the size, yet it offers unlimited music with streaming services. It’s a perfect upgrade for older audio systems.Overall, this device works great and adds reliable Bluetooth functionality to older receivers. Highly recommended for anyone looking to upgrade their audio setup effortlessly.

It works as intended and for that reason it should be 5 stars, however, the loud beeping sound it makes when it connects is incredibly annoying. I use this for the projector in my bedroom, at night, before I goto bed and the second this thing connects to it, it let's out thaan irritating loud beep. This is a pretty niche use-case though, so this probably won't effect most people using it for cars, etc. Hopefully they change this in future versions, a soft, quiet beep would suffice.

Great product. Does just what it should. Never misses linking itself when it is in the vicinity of a bluetooth device.

work and very easy to set up had no problems with it

Works as it should. Hooked it up to an older receiver with some a/v cables and crystal clear sound from all four speakers, center speaker and a sub with no problem. Worth it if you have an older receiver and want a bluetooth connection from your phone.

TL;DR- Esinkin works well but will takeover the Bluetooth signal from any other device in your house. There is no on-off button so you will need to unplug the power cord if it’s not the device you want to stream sound to. Also, multiple Esinkin’s don’t play well with each other, they’ll all try to connect regardless if you tell your iPhone to ignore one. They’re always powered on and trying to grab the signal and conflicting with each other.I have prewired speakers throughout my house and outside by the pool. There are 3 different areas/speaker setups that each require their own stereo amplifier running a speaker selector switch. I wanted to be able to use my iPhone to stream music to the stereo amplifiers in each zone, so I bought 3 of these Eisinkin BT (Bluetooth) receivers. They work great, are easy to setup, and are pretty powerful. And that’s the problem. If you have any other BT devices (ex: headphones, speakers, etc.) the Esinkin will “hijack” the signal and take it over. There is no power on/off button so you’ll need to physically unplug it to stop it from unintentionally grabbing the signal. Two of my amplifiers have power switches on the back that control when the Esinkin turns on/off, but the third doesn’t have that power switch. So every time I try to use one amp the other with the Eisinkin tries to connect to both, basically causing a conflict and not allowing ANY music to play. So if you want to use multiple Eisikin’s be sure your amplifiers have switches on the back that kill power when not turned on. Or simply do what I ended up doing and buy different brands so they don’t conflict with each other. I know it all sounds confusing but if you try it like I did, you’ll soon learn it doesn’t work well with other of the same units or other BT devices. A simple on-off button would help prevent always having to unplug the power cord.
