Sony ULT Field 3
Reviews
SoundGuys
While the ULT Field 3 packs a decent low-end punch in ULT mode, it’s a bit of a one-trick pony, sound-wise. If you’re not a fan of the ULT EQ setting, your only option is to use the custom EQ, which won’t give you the same bass-heavy performance—leaving you with a less-than-satisfying overall sound.
