Question: Will an iphone automatically re-pair with this device or do I have to go to settings and pair with it each time?
Document: There are plenty of Bluetooth speakers and stereos out there, but if you happen to own a &#8220;legacy&#8221; stereo that is still performing really well acoustically, then you are out of luck when it comes to streaming audio from your favorite portable media device to it. This is where this Brightech BrightPlay Bluetooth music receiver comes in. It is small, portable, and it works with either RCA or 3.5 mm jack. I was able to pair up my iPhone pretty quickly. I don&#8217;t own any NFC-enabled devices, so I was not able to test how well this feature works.
works great, just as advertised. easy to  pair with my iphone and ipod. will likely purchase another one.
Had a hard time picking up radio reception on my garage stereo and this device allows me to play any steaming audio site from my android phone.
I have used a few Bluetooth audio receivers in the past, but I really like the look and sound clarity of this one. At about (2" X 2" X ") and a sleek shiny black, it sits on top of my receiver and is barely noticeable expect for the gentle blue light that shows it's powered on. Paring is extremely easy and fast. My iPhone took less than ten seconds to pair (I held the phone within a foot of the receiver). After the first pair, I could pair it again directly from my sofa.The power for the receiver is a good length of cord attached to a somewhat bulky power adapter (approximately 2" X 1' X 1").
Worked great...easy to pair and set up. The range between the phone and the device was a little limited but overall I am very happy with it.
I've tried quite a number of Bluetooth music receivers over the last few years trying to find one that actually has good sound quality, and with the Brightech BrightPlay Live I finally found one. It doesn't have the &#34;been through a washing machine&#34; sound of the other brands I've tried, or the persistent annoying echo that comes with other brands when listening to spoken audio. It just sounds like it should.I also really like that it doesn't have a 'pairing' button that you have to press, which means I can bury it in my cabinet of electronics and not have to dig it out every time I want to attach a new device to it.
When disconnected from BT devices, it goes back to &#34;pair&#34; mode. The only missing feature is the on/off button which would make it a little bit more convenient to use. I don't like the idea that my neighbors can pair their devices with my stereo. As a workaround, I keep unplugging it when not in use. Still the device delivers what it promises and costs way less than other big brand name devices.
Small, inexpensive Bluetooth receiver. When plugged in and not connected to any device, it starts with &#34;pair&#34; mode. Any BT device can immediately see itand connect to it without a password. I plugged it into my 7 year old stereo system and I have been streaming music from all kinds of mobile devices since. Bluetooth 4.0 support is a huge plus as it consumes less power on mobile devices. It also has better coverage than my older BT speaker set. It still continues to work with iPAD for example, even when I move it to the next room (about 35 feet away).
I own a number of bluetooth receivers so when I was offered a review sample I was expecting yet another one that was indistinguishable from the others. This one is truly different. For one thing the NFC (near field communication) feature made pairing it with my Samsung Galaxy Note 3 phone a breeze. I literally touched the phone against the receiver and a message on my phone's screen popped up and asked if I wanted to pair with a bluetooth device. For my Samsung Tab 3, which is not NFC-enabled, this receiver popped up in a scan for new bluetooth devices, paired and connected within seconds.When I test a new receiver I look and listen for two things: (1) distance and (2) quality of streaming music.
The sound is exactly the same quality as if I was playing a CD. The device notes that 30-feet is the maximum for reception, which is true, but I found the 18-feet from my couch to the receiver was fine. I didn't even have to point my iPhone in the direction of the receiver. It simply recognized when I wanted to increase the volume, switch songs turn the sound off.The receiver can be left plugged in with the green light on. There is no On/Off switch, but you can unplug the output cord on the receiver or the power cord end from the wall.
Answer: If power to the device is lost (i.e., unplugged, power failure, etc.), you'll have to "Forget this device" from your iPhone and re-pair it each time. This makes it rather unsuitable for an automotive application, for example, where the device shuts off with the ignition. Unfortunately, I learned this the hard way. :)
