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 quality portable speaker
Got a good base kick.. looks good and is exactly what I wanted... Loud but not oppressively so for my ears.. Might not be loud enough for some if you want it banging... But for me was well worth the money.. Good clarity and with the bass boost off you can really hear the treble .. I haven't yet tested the durability but it is rated high and the rubber is thick over the ports .. So I imagine it will be quite durable.

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.

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.

Super impressive and great battery life
Really impressed with the build quality and sound. I have an ULT 7 but wanted something a bit more portable. The sound quality is exceptional with good separation and clarity. Punches above its weight for bass quality. Only negativities I haven’t managed to pair it with the ULT 7 but that’s not too much of an issue. Would completely recommend this exceeds expectations and I’ve found it suitable for small performance venues as packs plenty of Power.

It's Loud
Wow! An outstanding piece of kit, the video I posted doesn't do it justice, as to just how loud and clear this speaker is. The quality is amazing, very rich, full of bass. It's hard to believe the sound is coming from something so small. Music by Kryfold Sky Track 'Someday' Album 'Gazing The Obsidian Mirror' for those interested.

Altavoz fabricado con materiales de muy buena calidad. Al abrir la caja ya te das cuenta de que todo está cuidado hasta el mínimo detalle. Sony se ha unido a las compañías que apuestan por no usar el plástico en su packaging. El altavoz es más grande de lo que esperaba y ahora entiendo el sentido de llevarlo colgando. Resulta muy útil tanto el sistema de anclaje del asa como su transporte. Puedes llevarlo colgado y sin problemas. El emparejamiento se realiza de forma rápida y cuando lo vuelves a encender tarda un segundo en conectarse a tu dispositivo. En cuanto al sonido, es sencillamente muy bueno. Si conectas la opción ULT, amplificación de graves, el sonido es sencillamente espectacular, poderoso. Me ha dejado sorprendido. Los agudos y medios suenan muy nítidos a cualquier volumen. Lo he probado con mis canciones referencia de todos los estilos y géneros y realmente me ha encantado. La música electrónica suena espectacular, pero el jazz no se queda corto. La batería de duración de hasta 24 horas es una pasada, es ideal para llevarlo a fiestas y durante horas crear un ambiente agradable. En resumen, un producto muy bien fabricado, con materiales de calidad y lo más importante, un sonido realmente muy bueno.

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
