Sony ULT FIELD 5 Portable Wireless Bluetooth Speaker (White)

I bought this on 30 Nov for Xmas and it is working well after 2 days, although was slightly bigger than expected. But it is a step up from the Bose Sound Link 3 that it is replacing. albeit not as conveniently sized. I think I did prefer the Bose for convenience and adequate quality - but let's see how we get on with the ULT Field over time :)

I purchased the Sony ULT Field 5 and I am really impressed with the sound quality. It looks great and is simple to set up & use. friends and family have all commented on how good it sounds / looks with the light effect.

Perfect bass, Perfect quality, Perfect price, Perfect sounds

Sound is good. Product looks and performs well. Battery life isn’t 25 hours though not even close

We purchased this Sony Field ULT 5 speaker for our daughter. Knowing the high quality sound & build quality already owning a Sony Field ULT 7 speaker myself I knew exactly how good these speakers really are. Heavy, built to last & capable of taking the occasional knock also IP67 rated making this speaker water & dust resistant ideal for indoor or outdoor use. A supplied shoulder strap is also a welcome addition, not forgetting up to 30 hours of playback. Sound quality is punchy, crisp & loud. Bluetooth connection is straight forward & when using the Sony Connect App offers more control over the sound output tailoring the sound to your liking. Overall this speaker offers years of great entertainment.

It is Amazing. Great sound quality, especially LDAC set with Lossless audio.

The speaker has a lot of software issues, starting special the wireless connection and starting at the beginning of this month, i have not been able to use the speaker at all because it keeps crashing when I turn it on, and it wouldn't allow me to turn it back off even if I press and hold the off button. So I would not recommend this speaker to anyone else. I have been trying to reach Sony with no luck

I bought the ULT field 5 hoping for a major upgrade from the field 1, and I was not disappointed! This is a great speaker with great sound clarity and outstanding bass. I also like the light upgrade compared to the SES XG300/500 and the ULT field 7. Overall, I highly recommend this speaker!

[This review was collected as part of a promotion.] I found the ULT Field 5 very easy to set up after unboxing. The Bluetooth connection was easy, with a fantastic range and the connection has been flawless so far. The speaker feels very well built, with the usual expected Sony build quality. The speaker feels so well built that it should easily handle any knocks and scrapes from most travel and outdoor scenarios. Sony advise the speaker is dust and IP67 water resistant, in turn also rust proof. The weight of the speaker is over 3KG but it is quite portable as there is a handy detachable shoulder strap within the box. I really like the way the strap connects to the speaker, but I think the strap could have had a little padding fitted, to avoid rubbing the shoulder if carrying it for a while. The Sony ULT Field 5 considerably surprised me when it comes to sound quality and its ability to fill an outdoor space or room with it's powerful sound, for the size of the speaker. Sony advise another speaker can be connected to form a stereo pair, which I haven't tried but I must admit I'm tempted! One of the features I really like is that the inbuilt LED lights change to the beat of the music being played around the ends of the speaker. This is really good for party nights, but you can turn the lights off if you prefer to do so. The speaker works on its side or end but seems more natural to be placed in a horizontal position. The ULT button has 2 settings. ULT 1 is for those that like a "deep bass" feel but I found it doesn’t seem to spoil clarity at all. I this setting very good for Drum and Bass and also Rock music. The ULT 2 setting is known as "attack bass" and is more suitable for playing live music and this setting does fill a larger space with the feel of being in a live setting. With either ULT button setting there is no noticeable distortion, and both settings don't seem overpowering at all. With the ULT button switched off, the speaker gives more clarity for music genres that require more mid and high settings and anyone not looking for a "Bass fix" should find the speaker of very good general sound quality. It is worth noting there is in built sound field optimisation, which provides clarity of sound in noisy environments, perfect for those trying to listen to quieter music when the world around prefers to be noisy. The Sony connect app, allows the user to customise the 10 band EQ (and change other settings) of the speaker even further, although I haven’t really felt the need to use it too much yet myself. Battery life has been exceptional so far, as I have been getting around 25 hours from one full charge. The speaker also has a quick charge feature and with 10 minutes charging, you can be up and running again with around 100 minutes of playback time. It's also worth noting with the correct cable, the speaker can also act as a powerbank and charge a mobile phone, which is very handy for camping or days at the beach. Overall, the ULT Field 5 is a powerful well built hard wearing outdoor speaker and come rain wind or shine, it is a fantastic choice for most outdoor music listening scenarios.

[This review was collected as part of a promotion.] Mobile disco! I’ve had a number of portable music systems over the years, most have connected via Bluetooth and this has to be the easiest and quickest I’ve ever used. It connected very quickly to my phone and the app (Sound Connect) has a good interface that was very intuitive. I’ve used the speakers a couple of times at family barbecues and it’s been great. Most importantly they sound fantastic with a great range and awesome bass. Initially I found the flashing lights to be great, especially with the app controlling the moods but it took me quite a long time to figure out how to switch them off. There is a switch near to the input port labelled lights but this didn’t appear to do a lot, (Work in progress). You can turn them off in the app by selecting the very edge of a colour in custom. It’s heavy! It’s got great battery life but weight is the penalty you have to pay. If you haven’t got far to lug it, you will love it. If you have got far you need to start building up those muscles.

[This review was collected as part of a promotion.] 🎶 Sound Quality & Performance • Powerful, bass-rich sound: Dual woofers, two tweeters, and side passive radiators deliver a bold, room-filling soundstage. The signature “ULT” button toggles two bass modes—ULT 1 for deep, thumpy lows and ULT 2 for punchy energy. Reviewers agree it “packs in party-level lows,” with minimal distortion even at high volumes • Stereo capability: Can be paired wirelessly with a second Field 5 for stereo separation, or linked with up to 100 Sony Party Connect-compatible speakers • Tuning & clarity: Includes a 10-band EQ accessible via app, letting you dial down harsh treble or mid scoops (though some find mids a bit recessed without tweaking). ________________________________________ 🔋 Battery & Portability • Long endurance: Sony claims up to 25 hours of playback (studio conditions, lighting off). Real-world use at moderate volume shows roughly 23 hours; heavy lighting or bass reduce that to ~15 hours • Quick-charge & power bank: A 10-minute quick charge gives ~100 minutes of playback, with full charge in ~4 hours The USB-C port also doubles as an output to charge your phone. • Weight & design: Heavy at ~7.3 lb (3.3 kg) with optional shoulder strap, it’s portable for outdoor events but impractical for bags. ________________________________________ 💧 Build, Durability & Features • Rugged and splash proof: Sporty IP66/67 rating, durable fabric, rubber end caps, and recessed radiators mean it stands up to dust, drops, and even full submersion for 30 minutes. • 360° LED party lights: LEDs pulse to music and are customizable via app or buttons. Some find them gimmicky or battery-taxing; app-controlled lighting drains battery to ~10 hours, and lights at max volume drop runtime to ~2.5 hours. • Convenience extras: Physical controls, AUX-in, Bluetooth 5.3 with multipoint pairing, and long-term battery modes (“Battery Care” caps charging at 90%) .________________________________________ ✅ Pros & 👎 Cons Quick-List ✅ Pros 👎 Cons Huge bass and loud output Heavy – not bag-friendly 25 hr battery + rapid quick-charge Mids can get muddy in ULT mode Rugged, IP67 waterproof build LED lights drain battery fast USB-C power bank feature Bulkiness may be something to consider ________________________________________ Summary: The ULT Field 5 shines when it comes to sound power, endurance, and ruggedness—perfect for outdoor events and pumping bass lovers. Just be aware it demands space, drains power with lighting, and needs EQ tweaks for clarity.

[This review was collected as part of a promotion.] An exciting compact product that I tested both at a small birthday gathering and also while outdoors. Its size was enough to hold in a hand while the strap provided also helped it to be mobile. Pushing the ULT button is the additional base function and listening to my various genres was easy. The light show is also impressive. USB-C charging makes it easy to plug in anywhere so I found that super convenient. I absolutely recommend this product for wireless speaker enthusiasts
