SAVE $42.04: As of June 18, the Sony ULT Field 1 speaker in off-white is down to just $87.95, down from $129.99, at Amazon. That's 32% off and a new best price ever by 5 cents.

We're just a few weeks from Amazon Prime Day 2025, which is now four days long and runs from July 8 through 11. That means standout deals are already appearing, like a 32% price drop on the Sony ULT Field 1 portable speaker.

As of June 18, the Sony ULT Field 1 is down to just $87.95 at Amazon in the off-white shade. That's 32% or $42.04 in savings. Previously, we've seen it drop to $88, so this is a new best-ever price for the speaker by about 5 cents. We'll be keeping an eye out as Prime Day gets closer, as the speaker might drop even more. But if you're in the market for a new Bluetooth speaker, we can say with certainty that this is a great deal worth grabbing.

Mashable's Miller Kern tested the speaker last year when it launched and gave it not only a glowing 4.5 out of 5 stars review, but also a Mashable Choice badge of honor. Short for "ultimate," the ULT series of speakers was designed for the bass lovers. Thus, there's an "ULT" button on the side of the ULT Field 1 that boosts the bass power to "provide that extra oomph you don’t get from other portable speakers."

The speaker is waterproof, dustproof, rustproof, and shockproof, making it virtually indestructible for outdoor use. Plus, it can get loud AF. "I can’t imagine ever playing music at full volume in my apartment. This speaker would be amazing for beach days or barbecues, though," Kern writes in her review. Battery life is fine at 12 hours (but could certainly be better), sound quality is punchy and full, and the design is simple and sleek. Ultimately, for less than $100, it's a total steal.

If you don't feel like waiting until Prime Day to upgrade your Bluetooth speaker, we encourage snagging the ULT Field 1 at its biggest discount yet.
