I've recently purchased the Beyerdynamic DT 990 Pro's 250 ohm version after doing a fair bit of research on what headphones would suit me best. The 990's were in my price range and from all the reviews about them, I've come to the conclusion that they would be the perfect fit for a basshead like me who listens to a lot of edm/pop. Out of the box they sound pretty amazing already compared to my previous closed headsets (steel series siberia V2/corsair vengeance 2000) but they're lacking the bass I've heard they're so famous for. My current setup is that I'm powering them straight from my laptop which doesn't really have an amazing sound card but the volumes loud enough for my liking. I am currently burning them in to see how much I like them unamped because I am a little hesitant about shelling about another $100 for an amp. I have tried tuning the EQ to increase bass to max levels but it seems like there should be more. My following questions regarding the bass are:
1) Could it just be me? I'm used to closed headphones where they are sealed and I could really feel the bass thump. Since these are my first real pair of "audiophile" grade headphones, I'm not sure if the bass is really already there and I'm just not used to it since they're open or if I should even be expecting more.
2) Would burning these headphones in for another couple hours really increase the bass? So far I've listened to them for 30 hours and I can say they sound somewhat better than they did right out of the box but I don't think listening to them for another 50+ would help with the bass.
3) Would an amp help tremendously? I've read mixed reviews on amps, some say they barely help at all while others have said that they make a day/night difference. In my case, would an amp significantly increase the
bass to where I want it?
4) Could these headphones be defective? I think they sound fine just except for the lacking bass. Are there any tests to determine if this is how they are intended to sound?
