If you’re on a strict budget and can’t spend more then Sennheiser HD 202 II is the best fit. I have been using this product for 6 months now the build quality is decent, the most important thing the sound quality is really good and I’ve used 5-6 headphones under 3000 this is one of the best. I have used them for mixing and they have accuracy and detail needed. They aren’t perfect tough, they can make your ears sore after a few hours. The frequency range is quite good 18 Hz to 18Khz
