"title": "5.0 out of 5 stars Best SD Card and Radio Combo on the market!",
"body": "To start off the sound is really good, It actually has some bass to it, and the equalizer is nice for files that might have background noise, you can usually change it to a different one and it reduces any static. When I first got it I thought it would be large but it's actually as small as a smart phone just a little chubbier, sometimes I will slip it into my pocket to keep listening to it, its that small. The strap is really nice you can hang it somewhere to get better reception or get it closer to you for better sound. Its nicer than other radios you might have to plug in or have to be on a flat surface. It has good mobility. Surprisingly it has as good of reception as any antenna radios i have, I have no clue how it get's such good reception without an antenna but it really does. Some stations you may need to put it in a better place for reception but once again you have to do the same with an antenna Radio too. It really shocks me how well the radio comes in, I've had 2-3 other radios without an antenna and they get nothing. This thing is an outlier in that regard. The Bluetooth works as intended though I've only used it a couple times. The SD card mode is fantastic, It even has a shuffle option, It's basically an MP3 with a great speaker and radio. I do wish you could shuffle just a certain folder but other then that, you can even fast forward and rewind, it even shows you the file that's playing not just a number like other radios. The Aux mode actually works like an MP3 so you could plug this radio into your car and play files off of it through your car speakers, which is a very unique feature. It was around 30$ when I bought it, which is not bad at all. And last but not least it has a 2 year warranty on it, This came in really handy when I had it for about a year and a half and it started glitching out on me, Turning on and off and not playing full files (For context I had used it everyday, at least an hour for a year and a half). Well, I contacted Avantree and Riza Helped me out They we're such great help. I was confused on a few things and they with understanding and kindness would email me back and walk me through the steps again (We ended up exchanging almost 20 emails). I tested what they told me to try, and the radio had gone bad. So they sent me a new one and had me send the old one back free of charge. Didn't even have to pay shipping, Now I'm rolling again with a new radio and a new 2 year warranty. You can't beat that service for only 30 bucks nowadays. It was well worth it. So to anyone who want's something to play SD and radio with a good speaker this is it, look no further cause you found what your looking for. I highly recommend Avantree because they stand behind their product and have great service. I will be getting more of their stuff in the future due to that. And Thanks again Riza for all your help!

"title": "5.0 out of 5 stars Stylish, versatile and powerful little music player with great customer service!!!",
"body": "This review is for the Avantree 3-in-1 portable FM radio with Bluetooth. I've had many speakers that stream music, bluetooth speakers and just FM radios in my continual search for an interruption-free portable music experience that I can use while I'm working. This radio comes as close to filling the bill as any other speaker I've had. It's a nice little unit. My first impressions when I unboxed it was that it was well packaged, in an eye-appealing box. The box you almost hate to get rid of, it's got little magnets that help the lid to close soundly. It's cool and all, but the radio is what I'm after, it was a bit smaller than what I thought it would be, which is not a bad thing. It's lightweight too, which might make you think it's cheap, but you will be surprised. I did have a problem with my first unit. When I turned it on, the LCD display would light up, but you saw nothing. That's kind of a problem with a speaker like this that is multifunction. I did figure out how to set the sources I wanted without actually seeing what was on the screen, that was nice, but I knew this was a defect I couldn't live with. I wrote the email address on the support card that came with the radio and got a response within a couple of hours. I was all set up to return the unit to Amazon, no questions asked. And for my inconvenience, they gave me a code to get $10 off if I wanted to reorder the unit, which I gladly did. I left this review at 5 stars because although I had a problem, one I believe would be rare with this radio, the customer service was top notch and ready to make me a satisfied customer. It's not that common anymore to get customer service worth a salt, so I appreciate that, in addition to the really cool radio! I'm glad because the unit I received worked perfectly in every way. The LCD display is quite handy and it's also got a battery saving feature that kills the light after a short period. I've found the battery life to be very adequate and has lived up to the 8 hour claim. The nice thing about this unit is that the battery is replaceable. And I do love the Micro SD slot. If you have a lot of old MP3 music on a hard drive, you never have to worry about not having music if you fill a 32 GB card with MP3 music, it will be a long time before you have to hear the same song twice! The radio itself is stylish looking and has a strap that can be removed. My initial thought was that I was going to toss that strap, but the first time I hung it near where I was welding, I immediately appreciated it. I weld and fabricate, so I create a great deal of ferrous shavings and dust, which wreak hell on speakers in general (the ferrous dust gets pulled into the speaker magnets and covers them to the point that the speaker no longer works or works with much distortion. I try to keep anything with a speaker away from my welding dust, so the strap is handier than I first thought. The radio sounds suprisingly robust and crystal clear for such a small device. It looks to me like there are actually 2 speakers, each on opposite sides. This seems to give it more bass. It's a good sound in all modes. The radio even has a built in equalizer with some preset modes, so that's fun to play with too and each one has a noticable difference in sound quality. The radio is equipped with a pleasant female voice that helps confirm menu choices. To me, it's a classy feature that sets this radio apart from others. It's got a good FM tuner. The radio has an autoscan mode which is a good way to start. Let it run through and save the best stations, then you can go through and delete the ones you don't want or like. You can go to any station quickly by hitting the corresponding buttons on top. 102.5 would be 1-0-2-5 on the top buttons. When it does the autoscan, it saves the 30 best reception channels. These are the channels that the radio will go to if you hit the forward or reverse buttons. If you hard press the same, it will do a scan from that point to the next station that gets reception, regardless of the autoscan saves. The bluetooth is real easy to connect to other bluetooth devices and has a good range. 20 feet is about where I start losing the signal and music starts to get choppy. If it's a clear line, maybe further, and if you go into other rooms, it kills bluetooth badly, so that's just something to keep in mind. There's nothing wrong with bluetooth on this little radio. The Micro SD is my favorite feature of this radio. I used to have the Creative Jukebox type of music players. I had a Grace digital streaming player and I've had bluetooth speakers. None of them had the Micro SD capability that this has. The Creative Jukebox really didn't need it, but the Grace relied on a good wifi signal, which I know my welding equipment sometimes messes with the wifi signal and bluetooth too. Days where it seems that's the case, it's nice to have the Micro SD feature. I found out quickly that it doesn't support Itunes music format, but does support MP3 all day long. It also works as a portable USB drive when you plug it in with the provided micro USB cable. When you use this mode, it automatically goes to USB cable mode when you turn it on. If you are looking for a stylish, versatile way to play music, this is unbeatable. I love it!!!! Read more",
