REACHER Mini Waterproof Bluetooth Loudspeaker Built-in Mic, Micro TF SD Card, 3.5 mm AUX Line-in

I love this player. It WILL play music from an internal micro SD card as well as being a Bluetooth speaker, so it IS an MP3 player. It works with my 16GB mini SD card (you have to provide it), but not sure how much larger of a SD card it will accept. It comes with wires to charge the battery and one to connect it to an AUX input on other devices. It will accept headphones. It will not be recognized by your computer if being plugged in to load the SD card- you have to pre-load it with your music files first; the USB cord is just to charge it. When you press the well-made rubber control buttons, it announces the function of that button/mode (in English)...Very cool. This thing impressed all my co-workers. Time will tell how long the internal, non-replaceable battery lasts. The charge is good for around four hours, but many Chinese-sourced batteries seem to die out after a few months in my experience. For $17.00 and shipping, it's a Great product, and well engineered. It also sounds good with its two built-in speakers. The music is clear with no distortion, and it goes quite loud as well. I'll be buying more soon.

I love the versatility of this thing, Bluetooth, SD reader, and FM Radio. The battery life isn't spectacular, running the FM Radio I can plan on about 4 hours, just enough for a good baseball game, but it won't go far the next day if I don't get it charged. The sound quality is what I'd call good for a speaker this size, but don't expect anything too impressive, it is pocket sized.

battery life only 3 or so hours at 80% volume. Otherwise pocket sized fit, good connectivity and very good sound for its size. If you want compact, good sound for 3 hours or less, get it. If you need longer battery life, don't.

If you need to put a Bluetooth speaker in your pants pocket, this is a good choice.If you want a shirt pocket speaker, the slimmer ARCHEER Pocket Portable Bluetooth Speaker with Phone Stand Cradle and FM Radio, about $23 from Amazon, is a better choice in my opinion (it has an exposed woofer cone that might not do well in a pants pocket).This is primarily a Bluetooth speaker.The FM Radio is primitive (it finds the strongest stations and you can only move from one station to the next sequentially). Also, the built-in FM antenna is weak and very directional. You probably need to plug in a pair of earphones so that the long wire acts as a stronger antenna and can hang down the outside of your pants (you could use an old pair with the broken earplugs cut off as you only need the wire — don't worry, the jack is an input jack and doesn’t turn off the speaker. You may have to push the mode button twice to get the radio to work).Further, the mp3 player is also primitive in that you can only play the music tracks on your Micro SD card sequentially.Thus, the FM radio and mp3 player function similarly to some other Bluetooth speakers.Contrary to what another reviewer wrote, the 1/8" jack is for input only — it does not output to earphones. The purpose ostensibly is to provide a longer playing time by avoiding the power-draining Bluetooth method (plus, it provides the means of attaching a better FM antenna, as mentioned above).Also, the speaker must be turned off manually when you are finished listening to it to avoid draining the battery — it does not automatically shut off after not receiving a signal for a period of time.I like this speaker a lot.

I've sent this back. I purchased it to use in the shower, I like to listen to a local FM station in the morning while I'm getting ready. I initially tried using the FM function, but was shocked at how annoyingly loud this thing is when you first turn it on. "DEVICE ON" it shouts, while I'm trying to be quiet with my husband sleeping in our adjoining bedroom. There's absolutely no way to know what radio station you're tuned to, so you have to flip through each one individually to find your station. Meanwhile the same button for tuning is also for the volume, but you have to press them slightly differently. So while I think I'm tuning to a new station, I'm just turning up the volume, so it gets really LOUD with static. So I try to turn it down, but instead its tuning down to a lower station loudly. I finally gave up and switched to bluetooth mode, b/c I can stream the station from my phone. "BLUETOOTH ON" it yells at me again, while I cringe, hoping this ridiculousness hasn't woken up my husband. This thing is unusable.———-edit 2/1/19—————Fair warning about this seller, they do not like ACCURATE negative feedback and will harass you for it. So not only will the device yell at you, so will the seller. funny that they didnt put in the product description that the device is obnoxiously loud 😆 here’s what they sent me:Hi ThereThanks for your purchasing! We noticed that you had wrote a negative review for our product . Your review is ridiculous as we had described the product very clear on the listing. You should read carefully before purchased!--Sophi from REACHER

For the $17.99 that this blu tooth speaker cost the unit has, blu tooth pairing, FM radio and mp3 decoding with TF memory card capabilities that allow you to record all your music. You will be surprised at the sound quality of such a small dual speaker system (small bass and general range speaker). I have a stereo Altec Lansing blu tooth speaker that's 5x the size and the sound is surprisingly good for the comparison. The biggest problem is finding the song/FM station you want as there is no reference.
