Short answer: the Soundcore Boom 2 Plus is the lighter, more adaptable boombox; the Sony ULT Field 7 is the larger Sony option with a modest sound-quality edge over the older XG500. Neither begins with neutral tuning, so the intended use should settle the decision.
The Boom 2 Plus is easier to carry than most speakers in its class and offers reasonably deep bass. Its warm default sound adds upper bass and softens treble, but it can benefit substantially from a good EQ tune.
The ULT Field 7 is an improvement on Sony’s XG500, yet its bass still does not reach as deeply as the top-ranked speakers. It is the better Sony choice for listeners who prefer its format and want an upgraded sound, not a clear value win.
Buy the Soundcore Boom 2 Plus if a lighter boombox and adjustable tuning are more useful than a larger Sony design.
Buy the Sony ULT Field 7 if you prefer the Sony ecosystem and want its step up from the XG500.
There is a real battery-life gap here: the Sony ULT Field 7 is rated for 30 hours, the Soundcore Boom 2 Plus only 20 hours.

The Two Speakers In Full
Soundcore Boom 2 Plus: $179.99 Amazon B&H Photo Video eBay
Older model: the Soundcore Motion Boom+ (ranked lower, rated 2.9/5).
Pros: Quite a bit lighter than most of the other boombox size speakers. This speaker will likely move up as we get a good EQ tune that makes it a lot more neutral. Measured bass extension of 39Hz (-10dB).
Cons: Warm tuning meaning a rolled off treble and some upper bass boost. Reasonably deep bass, but not as good as the top ranked.
