esinkin Bluetooth Audio Adapter for Music Streaming Sound System, Wireless Audio Adapter Works with Smartphones and Tablets, Bluetooth Receiver for Home Stereo

Bought this so I could stream Spotify from my phone throuh a Kenwood stereo amp from the 1980s. Works perfectly. Bluetooth connects effortlessly. Simple, straightforward, and comes with a power supply and connecting cables. One note, streaming through Bluetooth does compress the signal so there will be some audio quality loss through any Bluetooth adapter, mostly really high frequencies and really low frequencies get eliminated. If you want lossless streaming you need to get a dedicated lossless streaming device, but simply need Bluetooth connectivity on an older device, this works great.

This little thing is absolutely amazing!! It works soooo well. I have an older (late 90s) NAD receiver that is incredibly clean power, but obviously no wireless capabilities. I mainly listen to records or CDs, but my 18 year old son loves to show me new music he likes and sometimes we sit for hours in the living room just going back and forth playing songs for each other from our phones.I saw this and figured, for $22 why not give it a try? It really is amazing, simply plugged in the included RCAs to a TAPE 1 aux (since i don't use a cassette deck) and plugged in power. Hit power button, turned on phone Bluetooth, and boom...started playing music.The range is great, I didn't scientifically test it out or anything but even walking 20 or 30 feet away it was functioning perfectly. IF you plan on doing 80+% streaming, a Wiim Mini or Pro would definitely be better and worth the investment. However, if you aren't strictly streaming and want to add streaming capability to an older receiver....this is DEFINITELY the way to go in both performance, ease of setup/use, and value. I can't recommend it enough!!

Worked perfectly. Straight forward directions, nicely packaged, everything I needed to connect to my tune from my phone.Bluetooth connected easily and was seamless connection with my S22 Ultra.Has dual power source for either 110v or USB power. Sound quality was great.

This works pretty well overall. I couldn’t get the RCA jacks to work with my setup... only one side of the audio would come in and the subwoofer would not engage. I was trying to connect it to a pair of 2.1 400W Logitech speakers in my living room, but using a 1/8" to 1/8" cable from the Bluetooth receiver to the speakers worked perfectly.I really like that it has a constant power source, so I don’t have to deal with charging a separate speaker to stream music or worry about it dying on me. Now I can leave my bluetooth speaker charged for when I want to leave the house. It’s also always ready to connect. Plus, I can have my phone plugged in and charging while playing music throughout the house, which is super convenient.It's also a lot smaller than I thought it would be and it is mountable with peel and stick on the bottom which is also nice.

The media could not be loaded. If this review helps in any way Positive or Negative Please hit HELPFUL!!! It will help encourage me to continue my real reviews of products I've purchased.Pros: $Priced under $25 / Synced fast to my phone/ Nice soft tone on speakers while syncing to let you know BT is discoverable (Note if you don't want then just synch device before turning on your speaker system/ Small/ Blue light is a nice touch/ Comes with cable and power adapterCons: BT is not new standard (That said I think new standard was designed for more than just audio and since this is purely audio system does not appear to be much of a limitation), Cable provided works but if you want high end sound you need better connectors (will cost you maybe $10 to $20 on up depending on how high quality connectors you want to get for hoking to this system), I can understand the power adapter, but since it is 5 volts and low amperage I think a USB cord option would be nice. Lastly no battery powered option although it would not be hard to rig up to a power bank.Okay... I've had this a day now and as you can guess I love this device. The range for the Bluetooth is awesome in that I can bring my phone all over the house and not loose BT connection to my stereo. Only thing I don't like about writing a review like this is that it also makes a good reason to raise the price.. Okay I guess with that said if the price gets above $27 for this great device I would look at my other options if I were to get some for friends.UPDATE: 9/27/2018 Yes there was a lot of background noise at the beginning of my review as my neighbor is having an underground pool installed in his yard; it was not noise from this device.Thank you for reading my review:Again Please give this review a thumbs up. It is real. I've been on Amazon as a customer for over twenty years. I don't get compensated for my reviews. (Not that I wouldn't like to be.) I pay for Amazon Prime so I get any of the perks that come with my Prime membership.

Very pleased with this item. The packaging is great and it came with everything I needed (including an actual power supply instead of a 6" USB cable. Hooking it up was a breeze. Connecting it to my phone's Bluetooth was a snap. It seems solid and the button has a nice positive click. No appreciable noise and it makes my streamed music sound like actual media playing through my hi-fi system. I've been looking for something like this for a while now, and this delivers in a small, sleek package. More importantly, it works and works well!

Why did you pick this product vs others?:I was looking for a product to integrate newer technology with a vintage receiver. This product met my need perfectly. I connected it to my Aux RCA plugs on the receiver, plugged it in, paired my phone to it and started playing Spotify in a matter of seconds. Easy. Works well. Affordable

Works great but only supports one device. Range was good. Sound quality was good. Didn't experience lag. Nice long cord for plugging in to power. I had problems with it always trying to connect to my turntable. Would have to connect to my phone before powering the turntable on.
