Minirig mk2 with subwoofer vs Sony ULT Field 5

Last updated: November 2, 2026

Short answer: the Minirig 2 with subwoofer for sound, the Sony ULT Field 5 for the outdoors. The Minirig is very balanced but not stereo and its app is buggy, and it costs $88 more. The Sony is IP67 rated, dustproof and water resistant, yet its bass is not as deep as others in the category and the sound is just okay.
