Avyzar AVZ-100 Intelligent Bluetooth Speaker Built-in Microphone, Portable & Powerful Stereo, Ultimate Portable Music Speaker & Hands-Free Speakerphone-Bluetooth, NFC Pairing, AUX & Micro SD Slot

First, I did NOT receive a discount on this item in return for an honest review. I actually bought it at regular Amazon price ($12) without any prompting. And I am glad I did. I ordered it on Friday, and it was delivered on Sunday. It comes in a box (not a blister pack), and has a small instruction sheet that is simple, clear, and not encumbered with dozens of ridiculous safety warnings. It took 2.5 hours to fully charge; the red LED comes on when it is charging, and goes off when it is done. I easily linked the Bluetooth to my Kindle Fire, and began playing music. The speaker is fairly heavy (a good thing) and seems very well made. It feels solid, and has rubber feet and a rubber-like shell. The buttons to operate it are invisible when it's off, but light up for a few seconds when you turn it on. While it's playing, the button lights go off and virtually disappear, but can be brought back on by brushing your fingertip across the telephone handset symbol on the right. It's a little annoying, but certainly not a deal breaker. Inside it this has two speakers side by side, and it is a true stereo. If you hold it up to your nose, you can hear distinct separation. Granted, at normal distance you lose the stereo effect, but the two speakers provide a richer sound than a single speaker would. The sound is very good, especially considering the size and price. I didn't notice any distortion at max volume. My wife uses it with her MP3 player and the included AUX cable, and she just loves it. She plays it while she's doing her hair and makeup. I listened to the 1812 Overture on it, and it accurately captured both the soft violins and the booming "cannons". I don't have a TF card, so I can't report on how that works, and we haven't used it enough to determine how long the battery lasts, but I am extremely pleased with this speaker.

***IMPORTANT UPDATE***I used this speaker for one charge cicle (10 hours). I stored it in its box for 2 days because i was busy with college's stuff. I wanted to use it one of these days, so I turned it on and i didn't hear the annoying voice. I didin't care that much, so I try to connect my phone. Surprise: no sound. Tried turning it on/off and happend the same. All i heard was some distortion in the sound. It died in two days that wasn't in use. It was a huge disappointment. Sadly, i'm no longer recommending it. Don't know if it was just my unit, or it's general. Please, buy with knowing there's a risk of it dying suddenly.I'm actually quite surprised with the quality of this little speaker, let's start with what I liked about it1. I love how it looks, it has a great design!2. It's range its pretty good. Sometimes i leave my laptop in the living room and I just carry the speaker with my when I move to the next room. Of course, don't expect it to be have a super range.3. Audio Quality. For it's price range, you get a pretty clear sound, and I was actually surprised how loud this little guy can be. For movies, it does its job pretty well.4. Battery life. I think those 10 hours are fairly enough.5. Has bluetooth, Aux and SD card, meaning it's gonna play music no matter what device you have.6. Super easy pairing. Turn on, search for the speaker, connect, enjoy.What I didn't like:1. That annoying voice each time you turn it on and connect to a device. It might not be a big deal, but for me, it is.2. The touch sensitive control just lit when you touch them, meaning that they stay turned off until you do so. It takes time to get use to where they are.3. No volumen controls. I think thay would be pretty usefull, I mean, you can play/pause without using your phone, but you have to go and grab it to turn the volume up/down.4. Static. I can hear it when the volumen is low, it's not that loud but it is there.5. No indicator when battery is low. Not even the little led light in the back blinks or something. I just charge it when it starts to sound weird.Overall, a pretty solid choice for it's price. By the time I wrote this review, it is at $19.99, but i bought it at a way lower price. Maybe you can wait for it to get cheaper, because at that price range there are other speakers that can be better than this one.I'm pretty happy with it and I highly recommend it :)

I almost didn't buy this because it sounded like one of those "too good to be true" type of things, where I'd just be wasting money on a cheap product that would either be worthless or break soon after purchase. However, after I read all the positive reviews and that it had an aux port, bluetooth AND EVEN NFC capabilities, I decided to risk it... even if it ended up being a bust, then it wouldn't be any big loss money-wise and it would be a lesson learned, right?! I mean, for $6.99, it was worth it just to see if all the positive reviews were justified.Well, I'm glad I did! This is an awesome little speaker! It has a little bass punch to it and gets much louder than I thought it would! Even at max volume, it retains its sound quality instead of sounding like crap. I love the fact that it is portable, it is so lightweight and it seems to last a long time between charges as well. This DEFINITELY does not look, sound, or feel like a $6.99 item.... what a deal...

I purchased this speaker to use to listen to recorded books, so what was important was that it was loud enough, and that the voices were plain enough at a louder volume to understand easily. Both of these were very good, and I was well pleased. Then after about 6 weeks of using it, when I went to plug in the charging cord, the plug inside came loose, and would not charge. I am careful, and it was never used by children, nor put into a position that would have put stress on the plug, so I assume maybe the welding just came loose or something, however it is worthless to me now.
