hello! i have been producing electronic music for some time now, and i bought monitor speakers (samspn rubicon r6a) at the beginning of the year. the monitors sound great in my opinion, there's only the problem: the bass/subbass. since the speakers don't go down to very low frequencies, i have always had problems to mix the bass and the subbass accurately and in my finished songs this frequencies do not sound perfectly right... now i am thinking about buying a woofer for my monitors, but it costs too much right now and i also think a woofer would not sound that good in my room. so i thought i could buy a good pair of headphones which i can use to get the low frequencies right. i only don't know which ones to buy... because i am producing electronic music like house or techno, they should be good for use in mixing the bass and the subbass! can anyone suggest headphones that would work for me? i thougt about a price between 150 and 250 euros (about 200-350 dollars). i already looked at the akg 271 mk2 (some say, they don't have much bass), beyer dynamics dt 770 pro (some say too much bass and not linear) and the audio technica ath m50 (good, but also maybe too much bass...). that's only what i have read on the internet, i had no chance to listen to them until now... does anybody know these headphones and can tell me if they are good? or are there other ones, that would be a better fit for me? hope you can help me! thank you!
