Short answer: the Vanatoo Transparent Zero Plus for better sound quality, the Neumi BS5P for the lower price. The Vanatoo Transparent Zero Plus ranks #13 of 36 powered bookshelf speakers at $499.99. The Neumi BS5P ranks #35 at $150, $349.99 cheaper.
What the Vanatoo Transparent Zero Plus offers: 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. Watch for: 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.
What the Neumi BS5P offers: Exceptionally broad connectivity for the price: Bluetooth, optical, coaxial and RCA inputs, remote control and 75W total amplification. Watch for: The original firmware Erin reviewed produces a pronounced V-curve—excess midbass and treble with recessed dialogue/midrange—and is a fidelity step backward from the passive BS5.
Buy the Vanatoo Transparent Zero Plus if sound quality matters more than the price. Buy the Neumi BS5P if the price matters more than sound quality.
If sound quality matters at all to you, skip the Neumi BS5P. It ranks near the bottom of the 36 powered bookshelf speakers, so look higher up the list instead.

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.

Neumi BS5P: $150/pair Amazon
Pros: Exceptionally broad connectivity for the price: Bluetooth, optical, coaxial and RCA inputs, remote control and 75W total amplification. The 5-inch fiberglass woofer/1-inch silk-dome platform has generally useful directivity outside port resonances and therefore responds well to corrective EQ. Compact dimensions and ample nearfield volume make it practical for a desk or small room.
Cons: The original firmware Erin reviewed produces a pronounced V-curve—excess midbass and treble with recessed dialogue/midrange—and is a fidelity step backward from the passive BS5. Nearfield treble above 8kHz rises as much as 4dB relative to farfield, distortion is already substantial at 86dB, and compression becomes severe above 96dB. Port resonances further contaminate the response. Erin later measured improved firmware, but buyers must confirm revision. Passive sensitivity and impedance are not applicable.
