Sony ULT Field 5 Wireless Portable Bluetooth Speaker, IP67 Waterproof, Dustproof, and Rustproof with Enhanced Bass, 25 Hour Battery, 360° Party Light, and Shoulder Strap (SRSULT50B), Black

Super speaker
Super speaker. Purchased Sony ULT Field 1, JBL Flip 6, Bose SoundLink Flex and SoundLink Revolve +II for comparison (give away Bluetooth speaker at end of annual international trips, so I go through a few of them). Have also had several UE Boom 1-3 (unbeatable speakers, but no longer available), and a few cheaper Bluetooth speakers. My criteria include: battery life, weatherproof, sound quality (realism rather than bass-heavy, although good base is required for projection, especially outside or when on boats or with much noise), size, portability, volume without distortion, affordability (~$100). All are comparable in most aspects. Full volume level is very similar, none distort, bass is a little more distinct in JBL. Soundstage is absent with all, but mid- to high-volume compensates for this, and projection is good with all. Running two UE Booms was a good way around this, but I want to carry only one speaker (traveling, in the garden, fishing, etc) and not deal with proprietary apps required to run two in stereo. The JBL beats all for portability (size, shape, hanger), with the Sony right behind (just a bit larger). SoundLink Flex doesn’t project quite as well, but is still a great speaker (when on sale and cheaper than the other two). The Revolve +II sound quality, projection, soundstage and volume beats them all, but is too large and expensive to carry on trips, so was just used as a comparison to what a Bluetooth speaker could do (nothing even touches the sound quality of the Sonos Move, that I borrowed from a friend – out of curiosity only – doesn’t fit my criteria of portability or affordability). In short – you’ll be happy with any of these three, but I’ll stick with the JBL and Sony until no longer available.

Things I wish I knew before I bought this.
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!SOUNDIt 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!!APPAs 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!STRAPThis 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.DESIGNAgain 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!!!

Excellent!!I am an audiophile! Having said that, I pay attention to all things sound quality related. If you are like me,MP3 files etc don’t cut it. This model was made for the demanding listener. Not all Bluetooth codecs are the same My FiiO M11+ portable player has Ldac and a 3.5Line output. Both of these feature are able to be utilized on the Sony ult field 5. I play dsd and ripped cd files from my FiiO to the Sony. The sound of the Sony is often described as bass heavy. Nonsense. This speaker on the ult2 setting is rich full and natural.The speaker walks the fine line between just enough bass to sound natural,(bigger drivers) and reasonablePortability. The amplifier has decent power output to get to enthusiastic loudness, but still sounds very natural at modest levels as well, and a substantial sized lithium battery to have long all day listening sessions. Like other reviews have pointed out, the colour changing lights are a surprise. They are not too flashy, or over done. They add to the experience.The carry strap is very well made with the ends being metal and not plastic. The sound quality is very well tuned and musical. It is not boomy overblown bass.If you play lesser quality low bitrate files on a lesserQuality Bluetooth codecs, then perhaps you will have a different sound.But careful examination of this models features and build quality and its weight,(7lbs) will tell you the type of audio quality to expect at high bitrate playback over Ldac Bluetooth or direct line input, which is necessary for excellent sound quality. This is a portable Bluetooth speaker for the discerning listener.Well done Sony!

Suena bien

Muy buenos materiales de construcción, gran sonido, tal vez no es tan alto el volumen pero no se distorsiona el audio.
