The verdict

The Sony ULT Field 5 delivers great sound with a hefty bass response, especially in ULT 2 mode. But if you’re the type who likes to fine-tune your audio, the complete lack of customization for the ULT presets might be a dealbreaker. The 10-band EQ helps, but it can't fully replicate the low-end punch of the ULT 2 setting. The ULT Field 5 might not be the right fit for listeners who want more control over their sound.
