I've decided on getting the dt 990 pros and I don't have an amp, but read that there is a 80 ohm version of the 990 pros, but can't find them anywhere. And it is easy to drive will work pretty much on any device, even a phone dongle. Music on the other hand is down to preference I'd say just get the 250 ohm 990 but that's only because there is more documentation and info about the positive sound changes that come from their pad break in, where as the 600ohm just has less info available Pretty much all beyer 250 ohm variants are the worst. While the Beyerdynamic get more bass, they also sound a bit sharp and piercing. Open comment sort The 990 also fit better and are easier on the ears. If you have a nice amp though and dont need portable listening you can go higher impedance. oj fq rv rz dh pr uo fr im mq
