Traditional Speakers Become Bluetooth-enabled
This Bluetooth Audio Receiver connects to any powered speakers or even your A/V receiver with a 3.5mm to 3.5mm or 3.5mm to 2RCA audio cable. Enabling Bluetooth capabilities in traditional speakers, the Roverbeats Unify allows users to stream music directly from Bluetooth devices to their favorite speaker. Any Bluetooth device, including tablets, smartphones, and computers, can play and control music on a sound system.
Easy to Pair and Re-pair + NFC Instant Connection
Connect mobile devices with one press and the speakers are ready. From then on, re-pairing is automatic and hassle-free. For phones with NFC, hold it to the Multi-Functional Button to make an instant connection.
Features Bluetooth v4.0 + EDR
Compared to earlier or older versions like Bluetooth V2.0, V 2.1, or V3.0, Bluetooth V4.0 consumes much less energy and lasts much longer. This Audio Receiver can run up to 10 hours per charge while charging takes only about 2 hours. EDR is short for 'Enhanced Data Rate', which ensures a faster data transmission rate and much more stable connection between a Bluetooth device and the Audio Receiver.
- The Roverbeats Unify maintains a strong connection for mobile devices up to 10 meters (33 feet). Stay connected while still having the freedom to move about. Just sit back, listen to the music and enjoy life.

***6 Months Update*** downgrade to two stars
Well after about 5 months this device started getting very finicky. When I was linked to it with my tablet or my PC every time I change screens I would hear a popping noise that came through my stereo speakers very loud. For example if I'm watching YouTube videos and then I switch to my Pandora. It makes a loud popping noise when it switches. Also the audio has become extremely quiet. In order to hear anything I have to turn my volume way up on my stereo. Something is wrong with this thing. It failed after 5 or 6 months. I will be looking to buy a different one. Two stars
Will report back with updates as time moves on.
After a few times where the connection to my devices seemed to suffer from interference, or just not a solid enough connection, I have found this:
Before turning the Etekcity Wireless BT 4.0 Receiver on, I make sure my device, in this case my iPhone, has bluetooth enabled (ON). Then, when turning the BT Receiver on, it automatically connects to the iPhone, and is ready to stream. Doing it this way, whether it's just me, or it really is a better way to connect, get me perfect streaming, a solid connecting, with no break up, or interference.
This little BT receiver is still a five star product, for me! Love it!
I also use NFC tags in my car. So when I get into my car I just
1)Turn on the Etekcity unit
2)Scan my NFC Tag with my phone which connects me to the Etekcity BT Audio Adapter and opens my spottily playlist.
And then I have everything set and ready to go in less than 5 seconds.
3)When I get off the car I just scan the same NFC tag again to turn off bluetooth, lower volume, and close spotify. I don't turn off the unit, seems it turns it self off after a certain amount of minutes or seconds.
I personally got some generic NFC tags from Ebay.
But you can get more or less any NFC tag from Amazon or wherever you want.
I also use the app 'Trigger" to program my NFC tags. But you can do whatever you want.
By the way, here is the cassette tape adapter I use
I do not notice any sound quality issues. And the battery seems to last decently long. I have used it for about 8 hours now, and I haven't charged it since it came out of the box two weeks ago. I don't do anything to turn it off when I leave my car. It seems it just turns off it self. The only thing I do have to do is hold the center button to turn it on and then pair/connect my phone to it.
The Circuit workout best demonstrates its range - on a gym floor with a full basketball court and the stereo off to one side I have full coverage through the entire gym. The Spinning class best demonstrates the setup flexibility - we can point the Spinners anywhere now, maximizing the use of the mirrors so everyone can get a good view of their form instead of staring at the blank wall where the stereo lives. It is exactly what we needed.
The one caveat that made it "practically" perfect: it's a little finicky about pairing when it is plugged in. Not an issue that would dock it a star since A: it has a good battery life and you don't actually need to plug it in except to charge it, and B: plugged in it works perfectly after futzing with it to get it paired.
I've used it in the car, and though I wouldn't make it my primary device for car use (it turns itself off when power is applied, not the other way around as is usual in car devices) it is really handy to have in a pinch.
I've already recommended this device to my coworkers, who promptly saw the utility. The one who immediately bought one loves it, doesn't want to run his Spinning classes without it anymore. I'm seriously considering getting another one to keep in my office for easy pairing there. So glad I got this!

But after about 6 months, it stopped taking charge. So essentially, as it works flawlessly in the interim... It becomes useless after a while.Read more
