I have experimented with several Bluetooth receivers now. Out of the five I've used are the Taotronics TT-BR01 ($25), the cheapest I could find with good reviews from MPOW ($16), an incredibly crap unbranded "HiFi" receiver intended for car use ($15), this one ($20), and the Esinkin knockoff of what is clearly a Logitech Bluetooth adapter.
The Taotronics one works great but lacks NFC. Main problem is after connecting you get like 3 seconds before the amp actually kicks in so the sound is very faint and then comes up at normal volume after that delay. It has lasted for me for quite a long time but the battery life has notably diminished over about 8 months. I use that mostly to make my headphones work like Bluetooth ones despite being 3.5mm jack standard. Never noticed a difference in sound quality between plugged in and using the receiver. Uses uncommon USB-A
MPOW sucked. It seemed to work well at first, but using it the same as Taotronics whenever I moved it cut out for most of a full second. Extremely annoying. Volume and skip controls was a nice touch though. at least it used standard mini-USB.
The unbranded adapter screamed distortion at me every few seconds. Just awful. Also was 8 times the size of this one but same size battery... why?
The Esinkin adapter functions just like the Logitech one at half the price. Just $23 was a steal for it, but it is pretty blocky. It also uses a weird 3.5mm barrel jack to charge despite using USB, which is a pain. I use that one for a stationary stereo system and it works well but if you are charging it and unplug it it disconnects for some reason.
Then there's this puppy. This $20, smallish but not tiny one-button receiver. The connection with this guy is second to none, worked great for me with a connection to my smartphone with the receiver sitting still while I walked around a room over 40 feet away. Never dropped connection once. When it connects, it's instant sound, unlike the Taotronics one. Again, comparing to Taotronics, they weirdly promise the same 10 hour battery life but this has a 200mAh battery vs Taotronics 145mAh. I expect this one delivers 10 hours even at high volume and Taotronics at lower levels. They have nearly identical one button controls and both use similar blue/red LED patters so at first I thought they used the same exact board but this seems to function better all around, so props to Etekcity, and the Taotronics one lacks NFC. This is also the only one of those besides the Esinkin adapter to come with not only a USB charging cable but also a wall adapter for it, plus both include an RCA cable adapter. And even better, this uses standard mini-USB so it works with the same cable that charges every Android and which I have like 7 of.
NFC is great. Fidelity is great. Haven't pushed the battery life much but so far - great. The rubber grip pad like on the Esinkin adapter would work well if the units weren't so lightweight, but it's decent. I planned to use this with a custom modified stereo system so I actually suck a thin steel sheet in the square space inside the rubber and stuck it with magnets in place, which surprisingly didn't ruin its functionality at all thanks to a steel plate of shielding already inside the unit from the factory.
Perhaps the best part of this thing is it just works. You connect to it in paring mode once or NFC once, and then any time both devices are on it auto connects. Keep it charged and you get no problems. If you want to extend the battery life of it, keep the volume maxed on whatever is plugged into it and adjust the volume from the streaming device so the signal produced by the receiver is as quiet as possible. I never noticed any distortion from this thing at high volumes or with a bunch of random things between me and the receiver including a closed door. It just works and keeps working.

Charger Broken, DOA. Decent Bluetooth Receiver. Easy to Connect and Use. Sound quality acceptable.
I purchased this bluetooth receiver for playing music on my speakers while I'm working. I've used Apple's Airport Express in the past and the connection always drops. I was considering Google's Chromecast Audio but then realized that you're limited to only being to play music through the Chrome browser or smartphones. Spotify seems to have problems on a Mac.The product is nicely packaged and does come with an RCA audio cable to 1/8" jack and also a 1/8" to 1/8" jack. It also comes with a USB cable and a charger. You can see the package contents in the pictures. However, the charger was dead on arrival and I was not able to get it charging. I ended up having to use my own charger for my phone in the meantime and will most likely have to purchase another charger to charge this since I plan on having the receiver connected to a power source permanently. You can see in the pictures that it is glowing red (charging) with my phone charger but not with the charger that came with the receiver. Fail!Pairing and connecting to my speakers was easy. Just hold the button until it turns blue to pair. Once connected with my Mac it automatically selects the audio output as the UNIFY speakers. If you can't see or don't know how to select, OPTION + CLICK the audio icon on your Mac to see the audio options. I've shown a screen cap.As other users have mentioned, you will notice a slight reduction in sound quality. I feel that it cuts some of the highs but mostly the lows (bass), however, it's still reasonable for a $19.99 bluetooth receiver.In conclusion, it's a decent receiver for being able to cast any audio from any device and any app. You're not limited to specific programs or platforms like you are with Airport Express or Chromecast Audio, which is really nice. I really wish I could give this 5 stars, however, the loss of sound quality and especially the dead/broken charger is a real drawback. I'm sure not all of their chargers are bad, but be forewarned that you may have to buy another 5V 1.0A output USB charger.
