ソニー ULT FIELD 5 ポータブルBluetoothスピーカー（オフホワイト）

Good bass,loud and well mad. Good on special for $299

This was a birthday present from my wife..she’s very particular in choosing and paying for substantial items.. she’s listened to most other brands before deciding on the Sony.. I’m glad she did..

Not great. With most Bluetooth speakers, the minute I turn them on, they connect with whatever device they are used to connecting with. Not the ULT Field 5. I have to go to my Bluetooth connections, try to connect, it doesn't work, I have to turn off Bluetooth, turn it back on, etc. Each time, I have to fiddle to connect the speaker. It's also not loud enough for my purposes even though it should be according to its dB info.

Bought it a few months ago and has been exelent for having outdoor jams.

Ult Field 5 what a great buy and love the great sound and bass that it makes, great quality product, love it.

I love my speaker i wish it had more settings for adjusting bass and etc. And I noticed that the nfc feature wasn't available on this speaker bit love the shoulder strap

I have recently purchased 2 of the Sony ULT Field 5 Bluetooth speaker's they have great sound output & I like that they have dual Bluetooth connectivity so I can have them connected to 2 Bluetooth devices and swap between them. The phone app is great as it gives you a graphic equaliser along with other adjustments

Very happy with the sound. Only thing I found misleading was that it could be turned on remotely but it actually turns itself off after a while and can only be restarted manually

Great sound for its size. Lights are ok. More of a novelty than a feature. Only bugbear is that I bought two of these with the intention of using Sony Connect for stereo sound. Sony Connect is very buggy. Often lots of static and doesn’t work well. Hopefully this is rectified in a Firmware update.

We were absolutely thrilled with this bluetooth sound box. My partner is a seasoned musician and really rated it excellent.

Upto 60% volume, music is good to hear but any further increase you will not enjoy the music as you notice bass reducing, distortion of sound and music is not really enjoyable.

The Sony ULT Field 5 absolutely blew me away. This speaker is an audio beast; powerful, clear, and loaded with bass that you can feel in your chest. The ULT (Ultimate) bass mode really lives up to its name, giving your music that punchy low-end without muddying the mids or highs. What stands out most is the crystal-clear sound quality even at high volumes. It doesn’t distort or lose detail, which is rare in portable Bluetooth speakers. Whether you’re playing rock, EDM, hip-hop, or acoustic sets, it handles everything with depth and richness. The battery life is stellar; easily hitting the advertised 25+ hours depending on usage. The build is rugged and waterproof (IP67), so it’s perfect for beach days, road trips, or parties. The LED lighting adds a cool visual flair without being over the top. Bluetooth pairing is quick, and the companion app lets you customize sound profiles, lighting, and firmware updates. You can also pair multiple units for a wider stereo effect, which is great for larger gatherings. ✅ Pros: • Deep, thumping bass with ULT mode • Loud, clear, distortion-free sound • Excellent battery life • Rugged and waterproof • Stylish design with lights • Great app control ❌ Cons: • A bit bulky for some backpacks • Lights can be cycled through the device but you need to fiddle with it which is which Overall, the Sony ULT Field 5 is a top-tier portable speaker—ideal for anyone who wants premium sound, durability, and features in one device. Highly recommended!
