Great bit of kit
I wanted something that was simple but robust enough to take a few knocks when I’m working in the garage and this came out top in my research. It’s fair to say that I’m not disappointed. The speaker is waterproof, dustproof, and rustproof with an IP67 rating, which is ideal for the garage environment. It can be used vertically or horizontally, so it has a small footprint, and doesn’t take up much room in the workspace, but I can also hang it by the carrying handle. It paired with my phone, my partner’s phone, and a tablet with no issues at all. To me, the sound is brilliant. I was warned that the bass might not be great, but it has handled all of my special ‘test the speaker out’ tunes and although there could be more bass, what’s is there is more than adequate for the average person, especially if you use the ULT button. I do have the option to add an additional linked speaker in the future if I want to. The battery life is good, too, and I can get at least 2 or 3 evenings out of it before it needs to be charged. All-in-all, a great bit of kit that’s worth the money. Recommended.

Faultless Sony
Great product from Sony. If you're looking for a very affordable, good looking speaker - this is the one. The ease of setup is great, just a simple NFC connection with your phone and you're good to go. It has a basic range of functionality, but it's more than enough. The ULT button adds a richer and deeper bass to the music, the speaker sound easily fills a room the size of a classroom for example. Overall a top Sony product.

Good but could be better.
If you’re hunting for a portable Bluetooth speaker that really punches above its weight, the Sony ULT FIELD 1 is one of the most impressive compact speakers I’ve used in a long while. From its powerful sound to its rugged build, Sony has clearly designed this model for real-life use — indoors and outdoors alike. 🎧 Sound Quality & Performance Right out of the box, this speaker surprises with rich, loud sound and enhanced bass that feels much bigger than its compact body suggests. Thanks to Sony’s ULT Power Sound technology and the dedicated ULT button, you can switch into a boosted bass mode that adds weight and impact to your music, making genres like rap, EDM, or pop feel exciting and vibrant. It handles mids and highs competently too, although some reviewers note that the sound can feel a bit compressed or grainy at peak volume — especially compared with larger, more expensive speakers. The audio also plays in mono by default, so don’t expect a wide stereo field unless you pair two units together. 📱 Connectivity & Features Pairing is effortless thanks to Bluetooth 5.3 support, and Fast Pair works on compatible Android phones for near-instant connection. The speaker also supports hands-free calling with echo cancellation — a handy bonus if you want to use it as a speakerphone. Sony’s Music Center app gives you some control over EQ settings and lets you manage multiple speakers. Plus, with Stereo Pair, you can link two ULT FIELD 1s for a wider, more immersive soundstage. 💪 Durability & Portability Portability is a big strength here. The compact footprint and lightweight design (around 650 g) make it easy to grab and go, and the IP67 water and dust resistance means you don’t have to worry about rain, sandy beaches, or spilled drinks. A convenient multi-way strap is included for hanging the speaker from backpacks or handles. With up to around 12 hours of battery life, the ULT FIELD 1 will usually last through a full day of listening — though actual life can be shorter at high volume or with bass boost active. 👍 Pros Impressive sound and bass for its size — lively and engaging. Waterproof & dustproof IP67 build, ideal for outdoor adventures. Bluetooth 5.3 with fast pairing and hands-free call support. Stereo Pair feature allows richer sound with two units. Long battery life for all-day play. 👎 Cons Default mono sound can feel narrow compared to true stereo. Some compression at high volume on complex tracks. Bass boost mode can be intense for some tastes. 🏁 Final Verdict Overall, the Sony ULT FIELD 1 strikes a great balance between powerful sound, rugged design, and everyday convenience. It’s a standout choice if you want a go-anywhere Bluetooth speaker that delivers depth and excitement without weighing you down. Whether for backyard barbecues, park days, or everyday listening, it’s a versatile performer that deserves its strong reputation.

Punches above its weight!
As a seventies teenager, obsessed with and totally absorbed in music.. and with whatever hifi setup I could afford to play it through.. I’m a latecomer to this digital world and have always felt that anything less than a trusty hifi separates setup was akin to listening to tinny transistor radios (I know, what are those any more?) Anyway.. fast forward to the second decade of the new millennium and even this dinosaur has to concede that however saddened he might be by just how differently we listen to music these days, the digital age does offer some real benefits.. and this is deffo one of them. Imagine telling my spotty fifteen year old self that one day he would be able to access an entire library of music, and even store the entire contents of his beloved vinyl collection on his very own personal telephone.. and listen to them on a small, portable, rechargeable speaker that would sound far better than any of the used (and invariably ‘blown’) speakers he’d been able to buy off school friends or second hand shops..?! I digress.. this isn’t the cheapest Bluetooth speaker obviously, but value for money for the sound and tone (resonant bass, without sacrificing clarity of higher ranges) I’ve not heard it bettered by anything in the same price range (and working with young people I get to hear a lot of portable speakers) Quality at a fair price..

Great speakers
I watched a lot of YouTube videos on various bluetooth speakers around this size range. Most agreed that while the sound quality is good, the bass is not as powerful as some of its competitors. That suited me as although I like bass, I don't like it overpowering. You can give the bass a boost with the ULT button if you desire and it certainly is noticeable. I'm certainly not an audiophile, but I do appreciate good sound quality and in my opinion, these speakers deliver. I decided to buy 2 of them as I read they can be linked using the Sony Music Centre app for stereo sound. It was easy to set this up with the app and the results are great. I connected them to my TV and it sounds so much better than just coming through the TV. Being portable you can space them far apart for a better experience. They also link to my turntable, phone, and iPad with no problem. They feel quality, look quality, and sound quality. Can't go wrong with Sony.

È una cassa da portarsi sempre dietro in auto motorino zainetto L'aspetto è fantastico, bello il design e l'effetto al tatto,con plastica siliconate e tessuto acustico, qualità costruttiva ottima Comoda l'impugnatura e stile accattivante. Su questo aspetto non c'è nulla da dire. Riguardo al suono Nel complesso il suono appare piacevole, i bassi sono presenti e danno una timbrica morbida e rotonda, gli alti spingono e conferiscono brillantezza A colpo d'occhio, ma forse dovrei dire " colpo d'orecchio" sembra tutto piacevole Ma la definizione lascia a desiderare Il suono è impastato e sembra poco naturale Perde dettaglio e definizione Non è la cassa che ascolti per apprezzare le sfumature, mi viene da dire che la preferisco spenta Il prezzo in offerta di 80€ riesce a innalzare il rapporto qualità/prezzo fino a renderla conveniente, poiché nel complesso fa il suo dovere. Ha di buono che l'angolo di dispersione è molto ampio, la puoi ascoltare quasi di lato rispetto alla direzione degli altoparlanti. La potenza è apprezzabile. Notevole anche la durata della batteria Un'occasione mancata per essere un gioiello da parte di Sony Suono voto 7 Estetista voto 10 Potenza voto 8 Batteria voto 8 Qualità costruttiva voto 10 Specifico che la mia valutazione si basa sull'apparecchio che ho acquistato, non ho avuto modo di ascoltare altri apparecchi dello stesso modello Qualora avrò modo di ascoltarne altri e dovessi riscontrare differenze lo farò presente nella recensione
