Short answer: the Sony ULT Field 3 for better sound quality, the Ortizan X10 for the lower price. The Sony ULT Field 3 ranks #64 of 150 medium speakers, rated 3.4/5, at $208. The Ortizan X10 ranks #134, rated 2.2/5, at $29.97, $178.03 cheaper.
Why pick the Sony ULT Field 3: IP67 rated, dustproof and water resistant. The tradeoff: Sounds a bit hollow, a bit boosted in the treble.
Why pick the Ortizan X10: IPX7 rated and pairs with a second X10 for stereo (TWS). The catch: Not much bass, very rolled off treble.
Buy the Sony ULT Field 3 if sound quality is the priority over the price, or the Ortizan X10 if the price is the priority over sound quality.

The Two Speakers In Full
Sony ULT Field 3: $208.00 Amazon eBay
Older models: the Sony XB33 (ranked lower, rated 3.4/5), the Sony SRS-XE300 (ranked lower, rated 2.8/5) and the Sony SRS-XB30 (ranked lower, rated 2.6/5).
Pros: IP67 rated, dustproof and water resistant. 24 hour battery life. App with 10-band EQ. Party Connect with up to 100 speakers. USB-C in/out for charging your phone.
Cons: Sounds a bit hollow, a bit boosted in the treble. Custom EQ and the ULT bass-boost button can’t be used together: turning on ULT disables the EQ. Bass is very weak with ULT off. Lost to the JBL Charge 6 in a side-by-side comparison despite being the larger speaker.
