How we ranked these synthesizers
Every pick has at least 100 customer ratings on Amazon and a listing with real specifications. The order mixes two things: how each model compares on the specs below (higher share of the best value in this group scores more), and how widely it is bought. The spec score runs from 9.0 to 9.8 and only compares these picks with each other. A spec the listing does not state is left out and the other specs are re-weighted; a listing with fewer than 2 stated specs is scored at half. We do not test gear in person. Full method.

Buying advice: synthesizer under 500
Decide analog, digital or hybrid
The engine type shapes everything else. The CRAVE runs a pure analog signal path with a 3340 VCO, while the NTS-1 pairs analog modeling with digital effects and the REFACE DX runs 4-operator FM synthesis. The Pro VS Mini and MicroFreak are hybrids, mixing digital oscillators with analog filters. Pick the engine that matches the sounds you want to make.
Count keys and check the sequencer
Key count decides how you play. The REFACE DX has 37 mini keys, the Pro VS Mini has 27 and the MicroFreak has 25. For patterns, the CRAVE names a 32-step sequencer and the Pro VS Mini a 16-step sequencer, while the NTS-1 and MicroFreak each name an arpeggiator.
Look at power and connections
Power and ports decide where you can play. The REFACE DX and Pro VS Mini run on battery power, and the Pro VS Mini adds USB-C. The NTS-1 connects over USB Type B, the MicroFreak over 3.5mm and USB Type B, and the REFACE DX over 3.5mm. The CRAVE uses a 2.5mm jack. Match the ports to your mixer, interface or headphones.
