Avantree Soundbyte T - 4-in-1 FM Radio with Bluetooth Speaker, Wireless Streaming to Bluetooth Earbuds or Home Stereo, MP3 Player via SD Card - Rechargeable Portable Device

I work at a convenience store and bought this to have a little background music. I needed something with an FM radio function as well as a micro sd card reader. This unit also comes with a two-way bluetooth function, meaning you can pair this with your phone and play music that way, or you can pair this speaker to most bluetooth headphones or earbuds for private listening. The FM reception is far better than those small pocketable tuners that you clip on your shirt. The sound is a decent full-range sound when listening in close proximity like on a work desk or coffee table. It has a rechargeable/replaceable 18650 button-top type, 2200mah battery. Extra batteries and corresponding chargers can be bought on Amazon for cheap for all-day listening pleasure. Music can be stored in different folders on a micro sd card and it supports common file types like MP3 and FLAC and has the option to either play on repeat, folder or shuffle. The EQ modes are; Voice (more like a traditional transistor radio), Bass (a bit muffled on the high end) and Balanced (a good blend). Volume goes from 0-30, though anything beyond 22 sounds like you're pushing it. FM offers seek and manual tuning and save up to 5 presets. The only minor flaws for me is that it simply isn't loud enough for larger rooms and some FLAC songs tend to have a crackle during play but can be fixed by first converting to MP3. Other than that, this IS a great speaker for your money. Most speakers in this category don't have all of these features and cost more.

First, I really like the unit. I like the SD card capability for storing .mp3 files. The sound quality is good. It looks classy and is built well. Bluetooth paired easily with headphones.I am disappointed in that it doesn't have two features that were on my earlier and much loved Avantree SP850. This unit (the Soundbyte HF) does not have the ability to fast forward through a stored .mp3 file on the SD card. That's handy for skipping commercials on a stored podcast or fast forwarding through part of a song. (it can skip to the next file however but not fast forward).The second feature missing is the ability to enter a song number on the numeric keys to play a specific song. You can skip songs with the forward and back buttons one at a time, but with 600 songs on an SD card, a direct key entry would be a great feature. Without a direct key entry, or a playlist, its very time consuming to navigate to specific songs.Update: 1/11/24. The Avantree Bluetooth connects to my MPOW headphones but often doesn't connect to my Sryhthm headphones. When it does, the Avantree says "connected" but no sound comes out of the headphones. The manual has clear instruction on how to connect. I suspect one party didn't fully meet the Bluetooth specification. The Sryhthm headphones do connect to all my other the devices including several tablets and phones. I still like the radio and may keep it. It still is useful with the very good MPOW headphones.

Sound is surprisingly good to this old man, though I guess an audiophile might be disappointed.Another reviewer seemed to stress how important to use Shuffle. I have no doubt the reason is that the device really has a difficult time with Folders on a Micro SD Card. It will support multiple Folders but only one level of Folder. If the SD Card has even one "sub-folder" it completely loses it's little mind and it gets stuck and will only play the first thing it comes to, ignoring everything else.Another quirk, it plays in the order stored on the SD Card. So if it's a symphony with several movements, they must be stored in proper order or it may be mixed up on playback. That's probably another reason Shuffle mode seemed so enticing - mixed up playback on most popular music wouldn't be so noticeable.Another example of being non-intuitive is the play/pause button - any device that's smart enough to display the desired track should be smart enough to recognize the play/pause button, but NO. After displaying the desired track the OK button must be pressed BEFORE pressing the play/pause button.And there seems to be no way to play a Folder once. Select a folder (an album) and it'll play forever.The FM Radio, and Bluetooth in and Bluetooth out work as expected.I only gave this player 4 stars and that was generous. The manufacturer should send it's programmer back to programming school because all the function seems to be in the hardware just terribly implemented.I'll probably not return this product because I invested so much time to figure out it's quirks. So if you're just looking for a nice little FM Radio that uses Bluetooth, this is a nice device. But unless you like shuffling ALL of the songs on your SD Card in a single massive group, get ready for a long learning curve.

This little guy is amazing. Excellent FM reception, station storage almost unlimited. EQ, Bluetooth for Bluetooth earbuds.It also has a 2mm mini jack input for older ear buds/headphones!6 stars if allowed!!

Delightfully pleased with audio from small bold sounding speaker. I paired it with my home system speakers first time paired. (easy pairing). Great value for all the features included. Pulls in the FM stations well. Small size makes it easy to take along. .21

Is a nice compact device and sound quality is good for FM stations that are in range. However, for price, it could have had a farther range/better reception. Station we wanted (which is somewhat distant) was not well received. Replaced with a Sangean portable unit that had much better reception.

Bought this radio to pair up with earbuds and it works GREAT! I was extremely impressed with the quality and great reception this radio has. Setup was easy (with the helpful video).
