– Sony ULT FIELD 1 - Wireless Bluetooth Portable Speaker with ULT POWER SOUND, Ultimate Deep Bass, IP67, Waterproof, Dustproof, Shockproof, 12hr Battery, Clear Call Quality, Outdoor, Travel - Black

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.

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.

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.

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.

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.

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.

Como alguien que viaja constantemente por trabajo, entre conferencias, eventos y exposiciones, he probado decenas de altavoces Bluetooth con la esperanza de encontrar uno que verdaderamente se adapte a mis exigencias: calidad de sonido, resistencia, autonomía y portabilidad real. Lo primero que noté al sacarlo de la caja fue su robustez. No es el altavoz más ligero que he tenido (pesa poco más de 1 kg), pero se nota sólido, bien construido, y el acabado transmite confianza. La correa desmontable para el hombro no es solo estética: realmente hace más cómodo el transporte cuando llevo mochila, portátil y equipo de presentación al hombro. Su tamaño es compacto (aproximadamente 24 cm de largo), y cabe sin problema en la mochila junto al portátil. Lo llevé recientemente a una presentación en Madrid y tenía que mostrar un vídeo con sonido ambiental y efectos para ilustrar una experiencia inmersiva. Conecté el altavoz al portátil por Bluetooth (la conexión fue estable y rápida) y activé el modo ULT. El salto de calidad fue inmediato. Los graves cobraron una profundidad que llenó la sala sin necesidad de subir el volumen al máximo, y las voces se mantuvieron claras gracias al equilibrio del tweeter. Este modo ULT no es marketing vacío: el sonido se siente más envolvente y con una presión acústica considerable para su tamaño aunque en mi opinión le falten un punto de agudos. El ecualizador de la app Sony Sound Connect me permitió ajustar los agudos y medios a mi gusto. En una habitación de hotel más pequeña, por ejemplo, suelo bajar un poco los graves para evitar saturaciones, algo que con muchos otros altavoces no puedo hacer sin sacrificar calidad. Por cierto, nada más emparejarlo con su app, me pidió para actualizar su firmware y me sorprendió que incluía una función tipo DJ para meter efectos sonidos durante la reproducción. En cuanto a autonomía, cumple lo prometido y me ha gustado la función de carga rápida (2 horas de música por solo 10 minutos de carga) mediante cable USB-C incluido. Sin duda un gran compañero de eventos, fiestas y viajes!

Excelente

Enceinte de petite taille mais de grande qualité, avec un son et des basses super puissantes. Pour un prix raisonnable. C'est du pur Sony!

Bardzo udany zakup.. super brzmienie. Sony nie zawiódł moich oczekiwań, na zewnątrz też dobrze brzmi.

Ho regalato questo speaker a mio fratello per Natale e ne è rimasto entusiasta! Il suono è davvero potente grazie alla funzione ULT POWER SOUND, con bassi profondi e puliti che si sentono anche all’aperto. La batteria dura tantissimo — lo ha usato tutto il giorno senza doverlo ricaricare. È compatto ma super resistente: impermeabile, antipolvere e antiurto, perfetto anche per le giornate in spiaggia o in montagna. La tracolla staccabile è comoda per portarlo ovunque. Il colore Foresta Grigia è elegante e moderno. Un regalo azzeccatissimo!
