Short answer: the JBL 305P MKII. It ranks #9 of 42 powered bookshelf speakers by sound quality at $319; the Vanatoo Transparent Zero Plus ranks #12 and costs $499.99, so there is not much of a tradeoff to weigh.
What the JBL 305P MKII offers: A fantastic value in studio monitors. Watch for: Possible slight hissing from the amps at low levels.
On the Vanatoo Transparent Zero Plus side: Genuinely neutral tonal balance in a small desktop-class powered speaker - a rarity in this size and price range, where the reviewer says most competitors have a scooped mid-range, one-note bass. Set against that: An 8th-order Butterworth high-pass at 58Hz sharply limits bass below that point - F3 measures 92Hz and F10 53Hz, so kick drum fundamentals and true low end need a subwoofer.
Buy the JBL 305P MKII. It ranks higher for sound quality than the Vanatoo Transparent Zero Plus and costs less, so there is no real case for the other one.

The Two Speakers In Full
JBL 305P MKII: $319.00 Amazon
Pros: A fantastic value in studio monitors. Extremely close to the Focal Alpha 50 EVO, almost indistinguishable. Surprisingly deep and wide soundstage. Good horizontal dispersion (~70 degrees). Has a proper limiter that controls output cleanly rather than crudely cutting bass, and holds up well under sustained loud playback with minimal thermal compression.
Cons: Possible slight hissing from the amps at low levels. Rear ported, can be an issue close to walls. A port resonance around 1.6kHz is audible and distracting on some tracks. Midrange is somewhat scooped rather than flat for a studio monitor, and treble runs about 1.5dB hot - Erin’s Audio Corner recommends using the -2dB treble shelf switch. Vertical dispersion narrows around the crossover, so try to stay within about 10 degrees of the tweeter axis.

Vanatoo Transparent Zero Plus: $499.99 Amazon
Pros: Genuinely neutral tonal balance in a small desktop-class powered speaker - a rarity in this size and price range, where the reviewer says most competitors have a scooped mid-range, one-note bass, and piercing V-shaped highs. Flexible mounting: flip the cabinet orientation to angle the tweeter up for flat-desktop placement or level for stand-mount ear height. Subwoofer output with auto-sense, so it engages automatically when a sub is connected. Wide input selection - Bluetooth aptX HD, USB (24-bit/96kHz), Toslink, and 3.5mm analog. Distortion stays reasonable (below 3%) up to about 88dB, and multitone distortion at max output (96dB) is the only real weak point.
Cons: An 8th-order Butterworth high-pass at 58Hz sharply limits bass below that point - F3 measures 92Hz and F10 53Hz, so kick drum fundamentals and true low end need a subwoofer. Very sensitive to ear height relative to the tweeter: sitting even slightly above the tweeter axis scoops out the 2-4kHz upper mid-range. Multitone distortion at maximum output (96dB) is high enough to add noticeable vocal graininess - stick closer to 88dB for clean output. The reviewer’s only real gripe is wishing it extended lower, which he acknowledges is an unreasonable ask for a speaker this size.
