Mashable's shopping team loves the Sony ULT Field speaker lineup, so we were thrilled to see many of the top models on sale for Prime Day. One of our favorites, however, was missing from the deals list: the ULT Field 7. Fortunately, after the sale wrapped up, the party speaker got a steep discount and you can save 30% if you act fast.

As of July 8, the Sony ULT Field 7 Bluetooth party speaker is on sale at Amazon for just $348. That's $151.99 or 30% off its list price of $499.99 and its best price all year. But stock is running low, so you'll have to add it to your cart ASAP if you want to secure the deal.

As our reviewer puts it, the ULT Field 7 features a boombox aesthetic that "exudes old-school swagger." But its looks are just a small party of why it earned a spot on our best Bluetooth speakers list. At around 13.9 pounds, you can still carry around the ULT Field 7, but it's more powerful than your average portable speaker. It's ideal for both indoor and outdoor listening, has a battery life up to 30 hours, is loaded with controls, inputs, and settings, and even features multipoint technology to pair it with multiple audio sources at once.

Beyond serving as a Bluetooth speaker, it can also connect to microphones and guitars for live performances. With the Fiesta app, the ULT Field 7 can even serve as a karaoke machine and pump out sound and lighting effects. It's essentially a party in a speaker-shaped package. As for the sound itself, our reviewer says it "fills any room with loud, engaging sound."

It's not the cheapest speaker in Sony's lineup, but at 30% off, it's much more palatable.
