Don't Need to be Confused just Buy This
Don't get Confused just buy it, you won't regret. Sound quality is top notch, great clarity for a bluetooth speaker. It supports HIRes bluetooth codec like LDAC not many speakers have these although you need to be a android user. For better experience and comparison i suggest to visit store to experience the by yourself. For portability, it is heavy like 3.3kg but solder strap is given and with solder strap the portability is not an issue. Battery life of this speaker is also good and you can use external power source like ac adaptor also with type c and get extra boost on bass and volume. Party light is also very cool. Overall is a great speaker total value for money in this price, (better sound than JBL xtreme 4). Build quality of this very top notch, have ip67 rating. In the functionality, the Sony's party connect is there if you have Sony's other speakers which have this feature. Can connect two same speakers as in stereo although the speaker it self is stereo. In the back io panel there is also a aux in port for audio and the speaker can be a powerbank to charge your phone. All these things which make this speaker great in functionality.

Powerful Sound in a Rugged, Compact Package
The SONY ULT Field 1 really surprised me with how much power it packs into such a compact, portable design. If you’re looking for a tough, travel-friendly speaker with serious bass, this one delivers — almost perfectly. 🔊 Sound Quality & Bass The sound is clear and punchy, with well-balanced mids and highs. But what really stands out is the ULT button — once pressed, the bass gets a serious boost without muddying the overall audio. Great for outdoor use or bass-heavy tracks. It’s loud enough to fill a room or fuel a picnic vibe. 🔋 Battery Life Sony claims up to 12 hours of battery, and that holds up well under moderate volume. If you crank it up or keep the ULT mode on all the time, expect slightly less, but still very respectable. 💪 Durability With IP67 rating, it’s waterproof, dustproof, and shockproof — ideal for hikes, beach trips, or poolside lounging. The build feels sturdy and premium, and the detachable strap is a thoughtful touch for carrying or hanging. 📶 Connectivity Bluetooth connectivity is fast and stable. It paired instantly with my phone and stayed connected with zero dropouts during use. There's also support for stereo pairing if you have a second unit. ✅ Pros: Compact and very portable Impressive bass with ULT mode Durable, waterproof, and dustproof Solid battery life Stylish, rugged design ❌ Cons: No AUX input (Bluetooth-only) Bass can be a bit overpowering for some genres No app support for EQ customization Final Verdict: The SONY ULT Field 1 is a fantastic speaker for bass lovers and outdoor adventurers. It's not perfect — some might want more sound customization or wired options — but for what it offers, it's a reliable, well-built speaker that sounds great and travels even better.

Powerful Sound and Solid Build
The Sony ULT 1 hits harder than a TIE fighter in hyperspace. Bass so deep even Darth Vader would nod in approval. Highs slice through like a lightsaber, mids stay calm like Yoda meditating, and the whole thing feels built to survive a Death Star blast. Connectivity is smooth, battery life goes the distance, and the build quality feels rock solid. Compact yet mighty, it’s the Jedi of portable speakers, balanced, powerful, and wise. Warning: play it loud and your neighbors might join the Rebel Alliance. Verdict: The Force isn’t just strong with this one, it is this one.

Ult field 5 & Ult field 3
Excellent sound quality, but Party Connect does not work with Laptop or TV at all I purchased two Sony ULT Field 5 speakers and one Sony ULT Field 3 speaker. The sound quality on all speakers is excellent. The bass is very powerful with ULT mode enabled, and the audio is clear, loud, and premium. Build quality is solid, and the lighting effects on the ULT Field 5 look very good. Battery backup is also impressive. However, there is a major issue with Party Connect mode. When I connect the speakers to a mobile phone or tablet using the Sony app, Party Connect works perfectly, and all speakers play audio together. But when I connect the speakers to a laptop or TV via Bluetooth and enable Party Connect, no speakers play audio at all. The audio completely stops, and none of the connected speakers produce sound. This makes Party Connect unusable with laptops and TVs. This is very disappointing, especially after investing in multiple Sony speakers expecting them to work together across different devices. Sony should clearly mention this limitation or provide a firmware update to fix Party Connect compatibility with laptops and TVs. Overall, the speakers are excellent in sound and build quality, but Party Connect functionality is limited to mobile devices only.

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 3.5 Line 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 reasonable Portability. 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 lesser Quality 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!
