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

I bought this Esinkin audio receiver to bring my old sound system back to life, and it has exceeded my expectations! The setup was very easy: I just plugged it in, paired it with my phone via Bluetooth, and within seconds I was streaming music.The sound quality is surprisingly good for the price, with no noticeable interference or lag. The Bluetooth range also impressed me — I can move through several rooms without losing the connection. Plus, the compact design doesn’t get in the way and fits perfectly in any space.Perfect if you have an old sound system without Bluetooth and want to upgrade it without spending much. I recommend it 100%!

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!

Very happy with this purchase. Use frequently. Sound quality good. No buzzing or humming. Stays connected to my apple tv between uses. Audio is properly synced. Worth the price. Would buy again.

I wound up buying 2 of these units because the first one works well (1 month in.) It connected easily to my phone, and the sound quality is great for Bluetooth. Signal distance is good too but that's also dependent of the transmitting device as well.The only con is that you have to have a clean power supply because the noise rejection is lousy (bad PSRR.) I initially powered it via a USB connection on my computer, and there was a lot of background noise in the audio. Using the included power supply completely eliminated that issue.Overall, it's a nice little item that does the job. To the people that complained about not being able to turn it off, I suggest reading the instructions; it's easy.

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.
