Sony ULT Field 5 Wireless Bluetooth Speaker – An Ultimate Breakdown
Here’s a closer look at everything the Sony ULT Field 5 Speaker has to offer, from design and sound performance to battery life and real-world usability.
1. First Impressions and Design
Out of the box, the Sony ULT Field 5 Wireless Bluetooth Speaker feels solid. Sony went for a boxy, robust shell with a shoulder-strap option that makes hauling it to a rooftop easier than you’d expect from a speaker this size.
The controls are straightforward: power, Bluetooth, party connect, and the new ULT button that immediately signals this is tuned for bass-forward fun. It also features a 360° party light array that’s subtle enough for home use and lively enough to boost a small gathering.
As a Sony wireless speaker, the Field 5 balances portable convenience with a premium fit-and-finish, which is a step up from Sony’s smaller pocket speakers and slightly more grown-up than some flashy “party-only” competitors.
Key specs at a glance
- Battery: ~25 hours (with lights off, typical usage) — great for day-long outdoor hangs.
- Water and dust resistance: IP67-rated, so splash, dust, and short submersion are accounted for.
- Size/Weight: Portable-but-substantial — light enough to carry with a strap, heavy enough to sit steady.
- Special features: ULT button for bass boost, Party Connect to link speakers, built-in powerbank, and 360° Party Light.
Those specs make it obvious why many people in India are eyeballing this model for outdoor use and parties.
2. Sound: Bass-first with Clarity
The Sony ULT Field 5 Wireless Bluetooth Speaker is tuned for fun. Press the ULT button and the low end gets emphasized, not just louder, but altered to feel punchier and fuller. This is exactly what you want from a speaker that bills itself as part of Sony’s ULT Power Sound line: impactful mid-bass that hits hard on pop, EDM, and hip-hop.
Reviewers found that while the speaker doesn’t recreate chest-rattling sub-bass (that’s physically very hard for a compact portable). It delivers excellent low-mid punch and clear treble that keeps vocals and guitars audible and lively.
If you prefer studio-flat sound, the Sony ULT Field 5 may feel a touch coloration-heavy, but if you want “party performance,” it nails the brief. In short, it’s a Sony wireless speaker built to excite crowds while staying usable for everyday listening.
Experience powerful bass with the ULT button, up to 25 hrs battery life with fast charging, IP67 rugged protection, ambient lighting, shoulder strap portability, Party Connect, and a 10-band EQ for custom sound.
Features that stand out
- ULT button: Instant bass shaping that gives the speaker two ULT modes to choose from. Great when you want a room-shaking presence without maxing volume.
- 360° Party Light: More tasteful than gaudy; it adds atmosphere without blinding bright strobe madness.
- Party Connect: Pair multiple Sony wireless Bluetooth speaker units to fill bigger spaces. This makes the Field 5 scalable for bigger backyard parties.
- Built-in powerbank and quick charge: Handy for topped-up phones when you’re outdoors and off-grid.
These features position the Field 5 well among other Sony wireless speakers that blend portability with party functionality.
3. Battery Life and Real-world Usage
Sony claims up to 25 hours of battery life under typical conditions with lights off. However, the real-world reviews confirm long runtimes that make weekend trips and all-day barbecues trivial.
Quick-charge support also gives a short surge of playback from a 10-minute top-up, useful for last-minute outings. If you want a Bluetooth speaker that won’t die mid-ceremony or picnic, the Field 5 is a reliable bet.
Rough Edges: What to Watch Out For?
- The speaker is not featherlight. Portability is reasonable, but this is more a “take on the shoulder” unit than a pocket speaker.
- Deep sub-bass (the kind you feel in your chest) is limited by physics; the ULT modes enhance perceived bass but can’t replace a big woofer. Reviewers note this is expected for the size.
- Even with those caveats, for users searching specifically for a Sony Extra Bass Wireless Speaker style experience (big presence, lively low-end), the Field 5 delivers what matters most.

How it Compares to Other Sony Picks (All Available on Amazon India)
If you’re comparing the Sony ULT Field 5 Wireless Bluetooth Speaker to other Sony options, here are three Amazon-available alternatives that target slightly different needs.

Great as a lightweight everyday or travel speaker that you can hang with the included strap.

- Sony ULT Field 3: A rugged, bass-focused outdoor speaker that’s bigger and louder than ULT Field 1. It offers around 24 hrs of battery, a strong ULT bass mode, IP67 toughness, fast-charging support, and versatile positioning for parties or outdoor activities
All three models above are available on Amazon and make excellent comparison points if you’re weighing the Field 5’s balance of portability, lights, and tuned bass versus raw loudness or extreme portability.
