Deal alert: The Sony ULT Field 5 Bluetooth speaker is available for $248 at Amazon. That’s equivalent to 25% off or a savings of $82. We named this newcomer the best midrange Bluetooth speaker available, and this discount puts it in a much more appealing price range.
If you were to ask me what my favorite new portable Bluetooth speaker of 2025 is so far, I’d have to say Sony’s ULT Field 5 speaker. When it launched back in April, I called it one of the best-sounding Bluetooth speakers I’ve tested in its size class. However, it cost $330, which is pretty pricey, though I suspected we’d see it discounted in due time. That has come true a few times already. The speaker has been marked down a couple of times since launch, first for Memorial Day and again for Amazon Prime Day. Now it’s on sale again, albeit at a smaller discount than during those big sale events.

In fact, a few other Sony Bluetooth speakers are on sale for good prices, including the new ULT Field 3 ($149 or $51 off) and the compact ULT Field 1 ($98 or $32 off). They’re all good portable speakers, but the ULT Field 5 has the best sound of the bunch and is arguably the best overall.
ULT is short for ultimate or, as Sony says, “The ultimate step into the evolution of its portable audio products.” Power represents “dynamic sound pressure and deep bass.” Sound translates to “as if you were in the front row at a concert.”
