Short answer: the Sony ULT Field 1 for better sound quality, the Ortizan X10 for the lower price. The Sony ULT Field 1 ranks #86 of 150 medium speakers, rated 3.1/5, at $138. The Ortizan X10 ranks #134, rated 2.2/5, at $29.97, $108.03 cheaper.
The case for the Sony ULT Field 1: IP67 rated, survives drops and 1m submersion. Watch for: Upper midrange peak, rolled off treble.
The case for 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 1 when sound quality outweighs the price for you, and the Ortizan X10 when the price outweighs sound quality instead.
There is a real battery-life gap here: the Ortizan X10 is rated for 30 hours, the Sony ULT Field 1 only 12 hours.
