Short answer: the Edifier MR3. It ranks #11 of 48 powered bookshelf speakers by sound quality, rated 3.8/5, at $149.99. The Fluid Audio C35BT ranks #35, rated 3.0/5, at $139, $10.99 cheaper, which does not close the gap in sound quality.
The Edifier MR3 is the more accurate pick. An affordable desk pair with balanced sound, Bluetooth, and tone controls, a good first set of monitors. Its measured preference score, a predictor of how neutral it sounds, is 3.91 against 2.57 for the Fluid Audio C35BT. Watch for: Local response ripples remain: the measured 300Hz-5kHz span is 4.5dB and listening-window narrow-band deviation is 0.538.
The case for the Fluid Audio C35BT: An inexpensive desktop pair with Bluetooth, balanced inputs, a front volume knob and a headphone jack for a basic computer setup. Watch for: Preference scores of 2.57 standalone and 5.57 with an ideal subwoofer indicate that the limitations are not just missing bass.
Buy the Edifier MR3. It is rated higher for sound quality, and the $10.99 saving on the Fluid Audio C35BT is not enough to make up the difference.
