Bests & Worsts Reviews from Amazon

This Bluetooth Receiver, Hi-Fi Wireless Audio Adapter, 1Mii Bluetooth 4.2 Adapter with 3D Surround aptX Low Latency for Home Music Streaming Stereo System (Upgraded Version with Power Adapter) is a truly excellent Bluetooth receiver. Formerly I had a computer attached to my Logitech Compact Speaker System Z320 for Notebooks which are excellent powered speakers (though they have been discontinued and you do not want to buy them now at the insanely high price dealers are asking). Because of certain aesthetics in our home, my wife wanted me to get rid of that computer and install a Bluetooth receiver in its place. (The speakers are in our foyer and she detested that a computer was installed there. I guess I can't blame her. The computer really did look out of place.) So, in the spirit of "a happy wife is a happy life," I ordered this Bluetooth receiver from Amazon the other day and I am very glad that I did. The sound produced from those speakers is at least the equal of what I heard via the computer and the ease of use, convenience, and aesthetics of having a Bluetooth receiver instead of a computer in our foyer is much more acceptable to her. This particular receiver has Bluetooth 4.2 plus AptX. Regarding sound quality over Bluetooth transmission at this time, that's as good as it gets. Setup could not have been easier. I didn't even look at the instructions (which are written in "Chinglish") until after I had the unit up and running. I connect its power supply to a switched outlet. When I activate the outlet, this receiver turns on instantly. First pairing was almost instantaneous. (And, as with most other devices of this type, you only have to initially pair it one time. Then it "remembers" your connection.) And now the connection to my cell phone is automatic and occurs practically instantly. Reception is excellent, as good as with any other Bluetooth receiver I own (and I own quite a few of them). There are two "levels" of sound quality. When the large round LED shows blue, that is "regular" sound. When the "3D" button is pressed the LED glows green and the sound is enhanced. I have been using the 3D effect exclusively. To my ears, it sound better that way. (You, of course, may disagree.) Though I am currently using this particular Bluetooth receiver in our foyer with different powered computer speakers (Samson MediaOne M30 3" Powered Studio Monitors (Pair) which sound much better than the Logitechs ([and are connected via AmazonBasics 2-Male to 2-Male RCA Audio Cable - 4 Feet, a capability that not all Bluetooth modules have]), it can be used with just about any audio system. It comes complete with cords enabling attachment to 3.5mm devices as well as to those, such as a receiver (any my amplified speakers), which have RCA connections. (I tried it temporarily with my 'main' sound system, which consists of, among other things, a Yamaha A-S701BL Natural Sound Integrated Stereo Amplifier (Black) 'feeding' a pair of Klipschorns, and it produced sound quality indistinguishable from the 'higher-end' AudioTech Bluetooth receiver I use in that system.) It has no internal battery; it operates via AC power only. Its power cord is such that it can be use in a car via the car's powered USB port or with a ENERGIZER 120W Cup Inverter 12V DC cigarette lighter to 120V AC to power laptop notebook & more w/ 4 USB ports 2.1A shared compatible with iPad & more or a Car Charger Quick Charge 3.0 RAVPower 40W 3A Car Adapter with Dual QC USB Ports for iPhone X / 8 / 8 Plus, iPad Pro 2017, Google Pixel, Sumsung Galaxy Note 8 / S9 / S8 / S8 Plus / S7 and More. So while it has no battery, it can still be used almost anywhere. It can even be powered via one of those Anker 2nd-Gen Astro E5 High-Capacity 16750mAh 3A Portable External Battery Charger with PowerIQ Technology for iPhone, iPad, Nintendo Switch and More or similar. What more can I say? It is a superb piece of equipment and I like it very much (plus my wife is pleased too) and I give it my highest recommendation. Thank you for reading this. Lawrence H. Bulk
