These are not really the same size class, and that is the honest framing here. The JBL Partybox 130 ranks #7 of 40 party speakers by sound quality at $449.95; the Sony ULT Field 7 ranks #43 of 76 boombox speakers by sound quality at $400.
What the JBL Partybox 130 does well: A relatively manageable 11.3kg PartyBox with removable battery, foldable handle, light show, USB audio and modern JBL connectivity. The tradeoff: It is still bass-forward and less clear than the PartyBox 120 in direct comparisons.
The case for the Sony ULT Field 7: Sony ULT Field 7 uses 2x 114mm x 114mm X-Balanced woofers + 2x 46mm (1.9”) tweeters. The catch: Bass is limited by its ~52Hz specification.
Buy the JBL Partybox 130 at $449.95 if you want a party speaker. Buy the Sony ULT Field 7 at $400 if you want a boombox speaker instead.
Battery life favors the Sony ULT Field 7: rated for 30 hours against 15 hours for the JBL Partybox 130.
Water resistance is not close: the Sony ULT Field 7 is rated at IP67 (brief submersion), well ahead of the JBL Partybox 130 at IPX4 (splashing).

The Two Speakers In Full
JBL Partybox 130: $449.95 Amazon eBay
Pros: A relatively manageable 11.3kg PartyBox with removable battery, foldable handle, light show, USB audio and modern JBL connectivity. Independent reviews describe it as unusually balanced and powerful for its format, while owner feedback praises clear voices and deep bass.
Cons: It is still bass-forward and less clear than the PartyBox 120 in direct comparisons. The smaller battery and stripped-back controls/features make it a questionable upgrade when the 120 is similarly priced. JBL’s wired daisy chain only works with other JBL speakers.

Sony ULT Field 7: $400 Amazon eBay
Older model: the Sony SRS-XG500 (rated 3/5).
Pros: Sony ULT Field 7 uses 2x 114mm x 114mm X-Balanced woofers + 2x 46mm (1.9”) tweeters. Its 6.3 kg, claimed 30 hours (Manufacturer specified) battery life, IP67 protection, aux input and stereo playback make it a practical option for its intended room or portable use. Measured bass extension of ~52Hz (-10dB).
Cons: Bass is limited by its ~52Hz specification. There is no companion app. A peak around 8kHz, and bass does not reach as deep as the top-ranked speakers.
