I just received it today 9/12/24 & after reading many reviews recommending to charge it 1st which I did . The led indicator changed from red to blue which contradicts the manual which states the led will go out . I I read an online review that stated it will change to blue when charged . Also it said to charge it for 4 hours which actually took 20 minutes . After charging the pairing procedure was pretty simple & straight forward . The 1st song I played was Lindsey Stirling Chrystalize which sounded superb with a great balance of treble as well as base . Song #2 is Round table Rival by her which again was superb , bear in mind that both songs were played at a low medium volume & didn't want to PISS off the queen . As I'm writing this review I'm listening to the West side story soundtrack . I've got nothing to compare this to other than desktop speakers so while this speaker sounds great to me it may not be for other people . While it's small & heavy enough to not blow away , it has a nice appearance , great sound , amazing that every note in the song is reflected in the 2 end LEDs . Again every instrument resonates well especially at a lower volume . I'm simply going to have to test it out in our 2 car garage where I can ramp it up . I just put on 1 of the most amazing opening acts ever recorded by RUSH . Being it's a recorded live show the sound is a little muffled but still worth listening too . How many bands do you know that feature not 1 but 2 operating clothes dryers & Jerry Stiller on the big screen . Switched the next song to the RUSH 2112 Overture which again is definitely worth listening to plus got better with a little more volume . Yes I like my older Rock music , I mean I'm 71 & stuck in the past music wise . Just put on Ted Nugent Stranglehold to see how it handles the back & forth synthesizer work which is also great . So far what I'm experiencing is a nice sounding somewhat small speaker that as of now seems to be worth every penny . As Pink Floyd Dark Side of the Moon plays , besides bringing back memories of my time in the USMC it makes me think of the genius of this band . So for the final songs , a couple from Saturday Night Fever to make an attempt to cover different styles & test this thing . I stand by my 5 star review as of now . Act 2 Yesterday I played it in the garage long enough & louder but about 5/8 volume , to play Rush 2112 & Pink Floyd Dark Side of the Moon while sanding & clear coating a workbench top . More than several times the music was interrupted by a quick burst of a fast busy signal . After completing the clear coat I noticed the LEDs were flashing red . So what's that , like 1:10 after starting to use it & I'm thinkin it's a low battery indication already , what happened to the 9 hours playtime on a louder setting . So I cleaned up & brought it in & put it on the charger & NO charging indicated on the LEDs . I verified the charger was indeed working by plugging my cellphone . I moved it to another room/charger & the same thing . OBTW it wouldn't turn on either & the thought that maybe it was too hot from being in the garage which the garage must have been 80 degrees . So I left it plugged in & about 20 minutes later it had flashing red lights & was in charging mode & responded to turning on & connected to my phone . We went out for dinner & about an hour later it again was fully charged . Out to the garage to sand ,& re coat the workbench top after 8PM & played it again while listening to 1080s greatest hits at slightly less then 1/2 volume & had no problem at all .. Either it somehow updated or downloaded an newer version or maybe it Exorcized a demon I'll never know . So hopefully it's now AOK . Possible Act3 to follow ; Well you guessed it , while having a late breakfast 9/15/24 I decided to reset the speaker by turning it on & holding down both volume buttons for more then 10 seconds . Of course it had to be paired again with my Google Pixel 7Pro XL . After pairing I played it on low volume for over an hour & no problems . I took it out to the garage & cranked it up to about 3/4 volume & everytime the LEDs turned red I thought it was going to low battery & die again . Only difference was the red lights were blinking & not solid . So I ended up playing it for a total of 4 plus hours & NO interruptions & no more what sounds like a couple seconds fast busy signals as I had before . In other words , I'm thinking we're all good now . As long as it performs as it is doing NOW , I'd definitely recommend it .

The sound quality is great, I think that the quality is above and beyond that of most if not all the other speakers in this price range. I could spend a little more money and get louder, but I would have to spend a lot more money to get more clarity. Or maybe I would be wasting my money to spend more. I will definitely buy again. I'll probably buy the next size bigger from Trelab for louder.

Bluetooth speakers are fairly simple. This one started out OK but after a while it began turning itself off after 15 minutes. It seemed as though it wasn’t charged so I changed cables and USB outlet connector and it turned blue appeared to be charged but it kept turning off. I to far out to return to Amazon so I called customer service but am yet to hear from them. It is useless as is. I will add another review if/when I hear from Customer service but would not recommend this unit! I gave it one star as zero is not an option. Later: Customer service called me and sent an email with trouble shooting options. This resolved the problem and i have had no issue since. The sound is very good. It is not an acoustic nervana but more than adequate for my shop. I have changed my grade to 4 stars and would recomend this speaker

Great sound and long lasting battery on a reasonably priced Bluetooth speaker. This sturdy little unit gets a very good sound and even has a good bass sound for it's size. I was impressed with the build quality and excellent sound from such a little speaker.I don't think you can go wrong buying this speaker.

The sound on this speaker is absolutely awesome. For its size it puts out so good sound. I like the color of blue so this fits me. It of awesome quality

I bought this is 2021 and use it almost daily. It has been a great speaker from the start. There was a system glitch with charging but once you figured out the work around the speaker works beautifully. It has been put to the test. Dropped many times over, including in a lake and the shower. I haven't noticed any battery issues or sound quality problems. I am still able to make calls with no trouble connecting and both parties are able to hear the other clearly.

Bought my first one about a month ago after borrowing & listening to the one my brother purchased some months back. This old lady in Augusta, GA says this is an excellent speaker. I use it while working in my back yard. Terrific sound. Bought one for my dear friend, too, because it's that great. So two thumbs up. You'll be glad you listened to me if you get your own. It shipped quickly. It also comes with two cables & instructions. One of the features is you can advance to the next song using only the speaker as the control.⁰p pop l

This is my best favorite speaker. We use this at the work place. Once you turn this on, it will automatically connected to my iPad mini from the next room. For the sound quality, we enjoy the loud volume with absolutly NO braking noise at all. I bought the different color (black) a year ago and it's still sounds great, but I wanted to buy one more for my kitchen crew. They love the quality of sound as well.
