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.

Unmatched Sound and Portability – Sony Nails It!
I recently picked up the Sony ULT Field 1, and I have to say—this speaker is on another level! The sound quality is absolutely phenomenal, with deep bass, clear mids, and crisp highs. Whether indoors or outdoors, it delivers a powerful and immersive audio experience that easily outperforms both the JBL Flip 6 and Flip 7. What really sets the ULT Field 1 apart is its portability. It’s compact, lightweight, and has a rugged design that’s perfect for travel, picnics, or beach days. The battery life is solid, and the water-resistant build gives me peace of mind no matter where I take it. Sony has done an excellent job blending style, durability, and top-notch sound in one speaker. If you're torn between this and a JBL, trust me—go with the Sony ULT Field 1. It’s a total winner! 🔥🎶

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.

Ultimate sound
Better than any other in this segment. The design is practical and portable, thanks to the strap. Battery life is top notch and sound is superb. A little low on bass than jbl series but the clarity is levels ahead

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.

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!
