Review: Excellent Speaker!!! - I looked at a lot of Bluetooth speakers at a local big box store to "test drive" them before purchasing. This model was neither the cheapest nor the most expensive, but it certainly checked all the boxes for me. I use it to "open up" my Martin guitars - the vibration of music simulates playing the guitar, which advances the maturity of the wood. The tone is deep and vibrant, battery seems pretty good, it pairs seamlessly with one of my old phones, it's portability makes it a great size, and it is ridiculously easy to use. They make devices that do this that cost upwards of around $300; this speaker is just as effective, more versatile, and way less expensive!
Review: Great little speaker - Great little speaker. The sound is amazing quality and it connected to my phone automatically when I opened the Sony app. It came with 60% charge so I could use it right away. The ULT bass boost is amazing. My friend had this speaker and it made me want to get it. She had the green, I bought it in white. I hope I never have to find out if it is waterproof or not. But so far it's been very easy to use and has been better than my last speaker which barely held a charge. I do miss my rbg lights on the sides with my other speaker, but I will get over it because this one has a better sound quality and better battery life so far. A much better choice, worth the price.

### ⭐⭐⭐⭐⭐ Excellent Speaker!!!
*by K***T on February 28, 2026*

This model was neither the cheapest nor the most expensive, but it certainly checked all the boxes for me.

Great little speaker. The sound is amazing quality and it connected to my phone automatically when I opened the Sony app. It came with 60% charge so I could use it right away. The ULT bass boost is amazing. My friend had this speaker and it made me want to get it. She had the green, I bought it in white. I hope I never have to find out if it is waterproof or not.

### ⭐⭐⭐⭐⭐ Things I wish I knew before I bought this.
*by P***T on May 20, 2024*

So, yes 5 stars, and I mean that. To cut to the chase, this is an excellent speaker, and you should get one! Now, I usually do not post reviews, but I thought if you knew all this, it would help you understand why I gave it 5 stars and recommend it so highly! SOUND It sounds way bigger than it looks. The ULT button adds a lot of bass and I love that! It is great for EDM, Hip hop, R&B, 80s, 90s,... I tried basically everything I could, and it all sounded great. Even added a little more depth to a classical cello playlist I listen to while I am working. If you like a less bass-heavy sound, just turn the ULT feature off, and it will sound excellent. If that does not suit you, there is a 3-band EQ in the app. OH, and it sounds just as good standing up as it does lying down!! APP As mentioned, there is an EQ in there!! You can also change other settings and even see the battery life, which I could not believe was still 60% after a couple of days of me casually using it! Super surprised because I never charged it when I got it! Oh, I also noticed the "group with other speakers," and apparently, you can pair another one of these and get stereo sound out of them.... I have not tried that, but I will as soon as I get my second one! STRAP This was one I was really unsure about when looking at it online. The strap is genius! It can tighten or loosen and then stay in place. My little one liked to carry it around like a purse, but it is really versatile, and I found I could hang it one way or another everywhere I went. DESIGN Again the design is great, it is very stable standing up or lying down. The buttons are easy to use and because they are raised, you can use them without even looking at them. The SONY logo on the front looks silver most of the time but actually has some... I don't know what, but it changes color, which is a nice touch. See pics. Love the Forest Grey color, it is exactly as expected. A subtle green/grey that I have gotten a lot more comments on than I ever though I would. LIFE/KID-PROOF! Ok, so I like music in the shower, and let me tell you... this thing delivers, even when it got wet it still sounded clear. I did not need to have it at full volume either. Of course, my girls heard it, and when it was bath time, they wanted to have it with them. That is when I discovered it could float!! Now it does not sound great that way, but it still played even after multiple "accidental" dunks in the tub! They also loved to see what they could put on the woofer part, and see it dance and fall out. Lastly it is stink proof, as well as mud, sand and waterproof... My daughters and I clean the pond behind our house, usually after big storms, and pick up plastic and other garbage we find. My 6 yo, who likes to hold the speaker as a purse, thought it would be a great idea to bring "Ultra" (that is what they named it) with us while we did so. As expected, it dropped into the stinky pond muck when a dragonfly landed on it, and she screamed and tossed it like a live grenade...after fishing it out, I rinsed it off with some dawn and the water hose and it was good as new. To say this has held up remarkably well is an understatement. It looks great, sounds great, and I would recommend it to anyone looking for a portable speaker. Hope this review helps!!!
