Best For
The Sony ULT FIELD 1 and Bose SoundLink Flex Portable are compact IP67-rated Bluetooth speakers designed for portable listening, but they take slightly different approaches. Sony stands out with a 20 W RMS output, dedicated ULT bass button, AAC support and a 30-meter Bluetooth range, making it appealing for users who want stronger, more energetic sound outdoors. Bose focuses on balanced, high-fidelity audio in a lighter and slimmer body, along with multipoint connectivity. Both offer Bluetooth 5.3 and up to 12 hours of battery life, so the better choice depends largely on whether you prioritize bass and output or a compact, balanced listening experience.
Verdict
The Sony ULT FIELD 1 is the stronger choice for users who want higher listed output, bass-focused listening and a longer Bluetooth range. Its ULT button also gives bass-heavy music an extra boost. The Bose SoundLink Flex Portable is better suited to listeners who prefer a compact speaker with balanced, high-fidelity audio and multipoint connectivity. Both are IP67 rated and offer up to 12 hours of battery life, making either suitable for travel and outdoor use.
