Review on Tronsmart Groove(Force Mini): Portable Bluetooth Speakers with 10W Power, Bluetooth 5.0, IPX7 Waterproof, 24 Hours Playtime, Built-in Microphone by Briana Fisher

All in all, these IPX7 Tronsmart Element Groove (TEG) speakers with 360° sound are awesome! Since these beauties feature TWS (True Wireless Sound) pairing, I immediately bought two as gifts and two more for myself. Pairing is very easy, not only with your SENDING Bluetooth device, but also with each other, because the Bluetooth 5.0 driver connects at lightning speed and offers a longer range than the Bluetooth 4.x driver. I connected TEG Bluetooth speakers to my Samsung Galaxy S9 Plus and Samsung Galaxy Tablet Tab A with 8.4 inch screen. I noticed that with these speakers there is an INDEPENDENT VOLUME CONTROL between the speakers and my Samsung devices. This is nice so that I can control the maximum volume of the speaker and also control the volume of the output devices (in this case my Samsung Galaxy devices) so that there is no distortion from high gain or volume when playing my music or others Audio output on speakers TEG To play my audio music (be it lossless AAC, MP3, OGG, etc.) on my Android devices I use PowerAmp (which I've had for years since I got my first Droid smartphone). ) because it allows DVC (Direct Volume Control) between my Bluetooth, wireless, and wired audio outputs. This way I get the most accurate and clear sound you can get from any speaker, especially for the size of these speakers (Dimensions: 4.05" x 2.94" x 4.05")! Another reason why I chose these speakers was the microSD card input, so if I want to go "offline" literally, I can download music to my microSD card and I have a "jukebox" literally offline. " Music playable with a 3.7V/2500mAh TEG battery for 24 hours of continuous music listening.If I want to "play again", I only need 2.5 hours of charging.Longer if you like the music longer than 24 hours if the speakers were connected to a 5V / 1A power supply, since (I assume) the 2500mAh TEG battery is charged via a separate charging circuit and the speaker of the TEG amplifier circuit The 10 -W output is powered separately from the internal battery so there is no hum or hiss when charging and listening at higher volume settings. for music from TEG.CONS:Tronsmart MUST provide a metal grille/gate on the BACK of this IPX7 speaker! Especially since they advertise it as a "Beach, Pool, Water Ready" speaker system! The internal speaker, which reproduces some bass sounds, IMHO is NOT PROPERLY CLOSED to external "unknown" objects such as sharp objects that can come in contact with the speaker and accidentally pierce the TEG. This may never happen, but the situation exists because there is no protection for that rear speaker. was short. Especially if you need to re-pair both speakers (if you have two). While it's great that the TEG is one of the only SMALL Revain speakers on sale that has an MP3 player with a MicroSD card, you'll need to have tweezers handy to remove that MicroSD card as it can folds behind a rubber connector that supports this speaker at the IPX7 rating level. Once the MicroSD card is in place and the rubber stopper is in place, this connector looks like it will rest on the end of the card itself. Overall, this speaker gets my 5-star rating, even with my mentioned CONS. I'm still looking for a case to protect the back of the TEG speaker for better "mindless" portability. (So I don't have to worry as much about tossing a pair of these headphones in my bag or car.) "I found today that it can easily accommodate an MSDXC card (not to mention the only one MicroSD card I have was a 256GB Samsung Evo Select test card [https://amzn.to/3Et3Eed] When trying to insert the SDXC card into "Music Reader" I found that it came with STICKER FACED DOWN and the drive should be inserted Mechanism features a spring-loaded snap-in feature that helps keep the card secure on the TEG speaker motherboard "Reader" also handles reading (or just ignoring) directories and folders I copied the entire music folder from my Samsung Galaxy S9 Plus to a Samsung Evo Select MSD card (using OTG 2 in 1 USB C to USB [3.0] female with PD charging port adapter m 60W [https:/ /amzn.to/2XqRHEQ] ), MSD formatting was FAT32. I I suppose it COULD handle NTFS formatting, but I highly doubt it, since these TEGs were made in China and are more "universal", I don't think it is. As for other music formats: AAC, FLAC/ALAC, WMA, OGG, WAV, CDA (CD-Audio), MPA, MPB, etc. I don't know, but I suspect that in addition to OGG and FLAC/ALC, I go of course assume that it can play these other popular formats without any problems. helped, no matter what I tried they didn't pair (which unfortunately) resulted in a good "mini stereo" OTG TWS 20W. We'll just have to settle for a 10W all-in-one OTG music system. I even tried using 3.5mm to connect my other TEG on a whim, FWIW, not good either! :) Hope that helps. Hooray!
