Short answer: the Vanatoo Transparent Zero Plus for better sound quality, the Edifier R1700BT for the lower price. The Vanatoo Transparent Zero Plus ranks #14 of 58 powered bookshelf speakers at $499.99. The Edifier R1700BT ranks #48 at $186.99, $313 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. 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. 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. 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.
What the Edifier R1700BT offers: Watch for: more V shaped, not quite as neutral sounding as the Edifier MR4
Buy the Vanatoo Transparent Zero Plus if sound quality matters more than the price. Buy the Edifier R1700BT if the price matters more than sound quality.
