Wrong choice…
I bought Tribit for 65$ first, thought higher price means higher quality, returned as it was a mess of all sounds, terrible. Then right after Amazon returned my guldens I bought Sony ULT Field 1. I am trying it third day in a row and i’m not happy at all. All these video reviews on tube and feedbacks on Amazon worth nothing. Why? Because you don’t know who has what experience, interests or anything else…age, income… So, ling story short- I have LG speaker PL7 and JBL C5 and Sony F1 is falls short compared to previous two. Ugly, very ugly bass, especially when you press ULT button in the middle of the song it spews on you weird sound, very disturbing and disappointing….Sometimes, when I see stuff like these, dashboard of Camry and hull design of Nissan Centra… I am thinking this these guys must have taken something strong…. Do not waste your money for ULT field 1, Tribits and rest …. Go for clear, soft almost perfect voice of PL7-you won’t be regret! Last advice- test first, then buy !

Received 2 different colors
I have no problem with the product Itself, i ordered 2 black speakers, i received one gray speaker. Why? I ordered 2 black speakers. What can i do with 2 speakers of different colors? I was in a hurry i wanted to use them for outdoor camping trip, i could order them elsewhere but they had only one black speakers. now i have to wait to return and replace, it is just a bad experience, all because the seller decided to send me a different color. Bad experience, the speaker sounds nice though

The Sony ULT 1 hits harder than a TIE fighter in hyperspace. Bass so deep even Darth Vader would nod in approval. Highs slice through like a lightsaber, mids stay calm like Yoda meditating, and the whole thing feels built to survive a Death Star blast. Connectivity is smooth, battery life goes the distance, and the build quality feels rock solid. Compact yet mighty, it’s the Jedi of portable speakers, balanced, powerful, and wise. Warning: play it loud and your neighbors might join the Rebel Alliance. Verdict: The Force isn’t just strong with this one, it is this one.

The SONY ULT Field 1 really surprised me with how much power it packs into such a compact, portable design. If you’re looking for a tough, travel-friendly speaker with serious bass, this one delivers — almost perfectly. 🔊 Sound Quality & Bass The sound is clear and punchy, with well-balanced mids and highs. But what really stands out is the ULT button — once pressed, the bass gets a serious boost without muddying the overall audio. Great for outdoor use or bass-heavy tracks. It’s loud enough to fill a room or fuel a picnic vibe. 🔋 Battery Life Sony claims up to 12 hours of battery, and that holds up well under moderate volume. If you crank it up or keep the ULT mode on all the time, expect slightly less, but still very respectable. 💪 Durability With IP67 rating, it’s waterproof, dustproof, and shockproof — ideal for hikes, beach trips, or poolside lounging. The build feels sturdy and premium, and the detachable strap is a thoughtful touch for carrying or hanging. 📶 Connectivity Bluetooth connectivity is fast and stable. It paired instantly with my phone and stayed connected with zero dropouts during use. There's also support for stereo pairing if you have a second unit. ✅ Pros: Compact and very portable Impressive bass with ULT mode Durable, waterproof, and dustproof Solid battery life Stylish, rugged design ❌ Cons: No AUX input (Bluetooth-only) Bass can be a bit overpowering for some genres No app support for EQ customization Final Verdict: The SONY ULT Field 1 is a fantastic speaker for bass lovers and outdoor adventurers. It's not perfect — some might want more sound customization or wired options — but for what it offers, it's a reliable, well-built speaker that sounds great and travels even better.
