Sony wants your next party speaker to hit hard. The company’s new ULT POWER SOUND series has just landed in South Africa, and whether you’re looking to power an actual house party or just want your music to rattle your bedroom windows, there’s probably a box here with your name on it.
There’s also Post Malone. Yes, that Post Malone — now the face of Sony’s “For The Music” campaign and the guy whose moody stadium sound makes a lot more sense once you’ve heard it blaring through one of these things.
The lineup includes two tower-style party speakers, a pair of portable field speakers, and a karaoke mic for those last-ten-minutes-of-the-night situations. Across the board, the branding is loud (literally), the bass is front and centre, and the design language is somewhere between “neon-lit Tokyo club” and “durable enough for a muddy music fest.”

The TOWER 9 is basically a subwoofer disguised as a speaker
The flagship ULT TOWER 9 is massive, both in physical footprint and sound output. It’s got four tweeters, two midrange drivers, a dual-woofer setup with Sony’s X-Balanced Speaker Unit tech, and a giant “ULT” button that acts like a shortcut to flipping your sound from loud to festival-grade. Battery life? A solid 25 hours if you go wireless. There’s also an AC-only version — the TOWER 9AC — that trades mobility for pure power.
What’s new here is that Sony’s not pretending this is a hi-fi product. It’s not trying to be subtle. The ULT button gives you two bass modes: one for deep sub-bass, the other for more punch. They’re labelled ULT1 and ULT2, which honestly sounds like difficulty settings for how much your neighbours will hate you.
You can plug in a guitar, go full karaoke, or hook it up to your TV — though if you’re pairing this with Netflix, maybe sit back a few metres.
The FIELD 5 and FIELD 3 are rugged enough for real life
If you’d rather take your sound on the go, the FIELD 5 and FIELD 3 are more practical. The FIELD 5 is the bigger of the two — 25-hour battery, IP66-rated water and dust resistance, and a shoulder strap that actually makes it feel portable. There’s also lighting and dual bass modes, because subtlety is not in this range’s vocabulary.
The FIELD 3 is slightly more chill. It’s got 24-hour battery life, stereo output via a full-range driver and tweeter setup, and the same ULT button for instant bass. And if you’re the type who likes your speakers to match your outfit (or your car), it comes in three colours: Off White, Black, and a forest-y green Sony’s calling Forest Grey.
And because this is a party lineup, there are microphones
Sony’s bundling the ULT POWER SOUND range with wireless microphones — the ULTMIC1 — which connect effortlessly and sound clean enough to survive bad renditions of “Circles” or whatever else ends up in the karaoke queue. They’re tuned for vocals and made to pair seamlessly with the TOWER speakers.
So, what’s this really about?
Sony’s clearly making a play here for lifestyle audio — and not just in a vague “music is life” way. Between the Post Malone partnership and the aggressive ULT branding, this is Sony saying: we make headphones for audiophiles, yes, but we can also build speakers for messy, loud, vibe-first music moments.
And if that’s your thing? These might just slap.
