Been looking for an upgrade Bluetooth speaker from my old JBL clip. This speaker sounds amazing. Loud and clear vocals. Fills up the room. Only used it for 4 hrs but everyone at the party was impressed with the sound quality and lights.

This is the ultimate portable Bluetooth speaker. It is sized, perhaps the be a party speaker. It has the capability to be loud, really loud and without distortion. It is built, arguably, to be a party machine, but for me, it is just a quality sound machine. Beautiful, detailed, delicate, defined, accurate and pleasing sound machine. This sounds beautiful. The reproduction and musical accuracy is remarkable. This speaker is definitely hefty, but with well made detachable shoulder strap it is very portable. The sound is incredible. The music detail is remarkable at normal room volume. The reproduction rivals a high quality stereo speaker. It is mono, but the sound of instruments and vocals is as clear and defined. The sound out of this Sony ULT Field 5 rivals a high quality stereo system. This Sony is made with all the quality construction, design and innovation promised by its name, but still, I was surprised to find such quality sound in a portable Bluetooth speaker. This sound great. Really. The Sony ULT Field 5 can certainly please those who love a booming bass sound. The top mounted ULT button will make those who want to impress with thunderous sound and extra bass happy. One button certainly powers a big bass hit. The power is there. The sound is there. The woofers, tweeters and side radiators must be doing their work to produce this total sound reaction. This is a hefty machine. This was made to produce sound and it does. I tried to peer into this, unsuccessfully, to figure out what was producing the powerful sound. I could see nothing through the grill. Apparently, there is a dedicated tweeter and woofer in addition to the two side passive radiator panels. The whole thing weighs about 7 pounds but I thought it was heavier. But only 7. I thought it was bigger too, but is only about 13inch long and 5 inches deep. It comes with a detachable shoulder strap that is easy to attach and remove. The easily removable strap ensures the UTL Field 5 keeps its refined good looks when not being moved about. I suppose I figure it must be bigger and heavier because of the sound it produces. It certainly sounds bigger than it is. It is made to be safe and secure for outdoor party and holiday use. It has a IP67 rating which ensures the highest level protection from dust and sand band very high level of protection from water damage. This will survive both parties and thunderstorms. What is remarkable for me is that this provides such a high level of sound quality and protection from dirt and water too. The dust and waterproof so not at all to my ear compromise the sound quality. The input/output charging ports are accessible via a small, secure gasket protected door on the back. The back panel is where you will find the light control button to turn off if you wish the discreet and lovely light strips that illuminate this UTL Field 5. Also, the back panel contains the dual function USB-C charging port and DC output if you wish to charge a cell phone for example. Also is a 3.5mm Aux audio in port. It charges fast too via USB-C and a 10 minute charging boost will provide for more than an hour of sound if needed. The Bluetooth functions perfectly too as expected from the most recent BT version. This is a quality machine that produces great sound. The electronics in this machine are state of the art and meet all the expectations the Sony name promises. This ULT Field 5 delivers the promise and provies it with the sound it makes and the reproduction it delivers. This Field 5 is a whole level beyond the standard Bluetooth speaker. This produces beautiful sound for daily listening but has the ability to move outside the home or office to produce the musical backdrop for any party setting, poolside event or at the seashore for picnic. One push of the ULT button boosts the base and another push boosts the power. Sound and Power both. This Field 5 can go anywhere and has the power to deliver sound for an all-night event. Rain or shine too. No fears taking this anywhere. It will deliver party pleasing sound indoors or outdoors.

Anyone familiar with Sony's product know they don't make junk. Actually this would be my 3rd Sony speaker product. I would consider this portable speaker a medium size unit. It charges via USB Type-C on the back port that has a solid rubberized cover. The top portion of the speaker is where all the controls are. Setting up and pairing the speaker to my laptop or smartphone was painless and super easy. Though I didn't download and install the app. I was able to control the volume from either the laptop or phone. So how was does it sound? Well for a medium size. It gets loud but for some reason, this one unit get a little bit distorted when the volume reaches around 80%. The high and mids excellent. The bass, once you turn it up and even after messing with the ULT settings is a little disappointing. If you listen to rock with a lot of bass. Don't expect this speaker to have that solid tight bass. If you like pop and especially classical. This is the one speaker you want. The mids and high are clear and there literally no distortion even when the volume is maxed out at 100% So far I been using the speaker extensively for over hours listening to classical music on medium and the battery lift is great. Pairing is fast and simple. The sounds overall is again, great for pop and classical music. In fact I personal think it sounds better than the "J" brand. Overall the speaker is well made though the cloth type grill the wraps around the speaker. I might think it might drag and snag on things if you use this outdoor. Again, another great product from Sony as always. Knocking 1 star off for the cloth type cover and the lack of a solid bass.
