The difference between headphones with 250 ohms and 600 ohms lies in their impedance levels. Headphones with higher impedance, such as 600 ohms, require more power to drive them and are better suited for professional audio equipment or headphone amplifiers. On the other hand, headphones with lower impedance, like 250 ohms, can be driven by portable devices such as smartphones or laptops. The choice between the two depends on the intended use and the equipment available to drive the headphones. **

The better variant of the beyerdynamic dt 990 depends on the specific use case and the equipment it will be paired with. The 250 ohm version is generally more versatile and can be easily driven by most devices such as laptops, smartphones, and audio interfaces. On the other hand, the 600 ohm version is better suited for professional audio equipment and high-end headphone amplifiers, offering potentially better sound quality and more dynamic range. Ultimately, the choice between the two variants should be based on the intended use and the available equipment for driving the headphones. **
