#41 Sony ULT Field 5: $198 Amazon eBay

Pros: A tough 3.3kg portable with IP67 protection, LDAC/AAC support, aux input, a 10-band app EQ, Party Connect, USB-C power-bank output and a claimed 25-hour battery. Reviews find it energetic and dynamic with substantial bass, enough volume for a yard, and two ULT modes that let bass-focused listeners choose a deeper or punchier presentation.

Cons: It prioritizes bass and loudness over fidelity: reviews find the upper mids and highs subdued, with limited stereo separation and soundstage depth. Deep bass is less authoritative than the enclosure suggests, and the loud confirmation tone when pressing the ULT button is an unnecessary annoyance. Use the app EQ and audition it before buying for detail-focused music.

Related speakers: Sony ULT Field 1, Sony ULT Field 3, Sony ULT Field 7.

How it compares: Just above it: Devialet Mania - $701 more, 15 fewer hours of battery life. Just below it: Sony SRS-XB43 - $48 cheaper, 1 fewer hours of battery life.
