JDS Labs Subjective 3 三頻段等化器

Tried the mid-band control first—it pulled vocals forward just enough to make old recordings feel fresh, though the treble knob is a bit touchy near its max. A fun little box for when you want to color the sound without overhauling your setup.

The bass knob gives a noticeable thump without muddying the mids, which is exactly what I wanted for my jazz records. It’s a straightforward EQ that’s fun to play with, and it’s made my headphones sound more alive.

The knobs have a satisfying, smooth resistance that makes fine-tuning the bass, mids, and treble feel precise rather than fiddly. It's brought a fun new dimension to my headphone setup without any noticeable noise floor.
