Short answer: the Edifier MR3. It ranks #8 of 24 powered bookshelf speakers by sound quality, rated 3.8/5, at $109.99; the Fluid Audio C35BT ranks #19, rated 3.0/5, and costs $139, so there is little reason to consider the other one.
What the Edifier MR3 does well: Erin’s measurements show little overall tilt across the listening window, helping voices retain a broadly natural balance at a desk. 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: Balanced TRS inputs, Bluetooth, front volume control and a headphone output make this inexpensive pair practical for a basic desktop 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 than the Fluid Audio C35BT and costs less, which makes it the one to get unless you need something the other one does better.

Edifier MR3: $109.99 per pair Amazon eBay
Pros: Erin’s measurements show little overall tilt across the listening window, helping voices retain a broadly natural balance at a desk. Scores of 3.91 standalone and 6.53 with an ideal subwoofer support it as a useful budget nearfield option rather than a reference monitor. Tone controls and app-based EQ provide unusually flexible adjustment, and its bass extends farther than the Fostex PM03’s. Measured bass extension of 70Hz (-3dB), with a measured sensitivity of 83.3dB.
Cons: Local response ripples remain: the measured 300Hz-5kHz span is 4.5dB and listening-window narrow-band deviation is 0.538. Bass reaches -3dB at about 70Hz. The limiter protects the drivers but prevents much extra loudness when pushed; existing compression testing puts effective single-speaker output around 86-87dB at 1m. Vertical crossover interference makes tweeter height and tilt important.

Fluid Audio C35BT: $139 per pair Amazon eBay
Pros: Balanced TRS inputs, Bluetooth, front volume control and a headphone output make this inexpensive pair practical for a basic desktop setup. ASR’s measured -3dB point is about 78Hz, so it covers more upper bass than the shallowest-reaching mini speakers.
Cons: Preference scores of 2.57 standalone and 5.57 with an ideal subwoofer indicate that the limitations are not just missing bass. Listening-window narrow-band deviation of 0.555 and sound-power deviation of 0.657 show that response irregularities affect both direct and room-reflected sound. A subwoofer cannot correct those tonal problems, and the small drivers are not a basis for expecting high clean output.
