Thinking about getting a pair of DT 770s. Not sure if I should go for the 80 or 250 ohm version. I found this in the FAQs section of Beyerdynamic's site. "The transducers of the 80 ohms versions are stronger and more powerful, a bit more low-mid accentuated and therefore this version is ideal for powerful reproducing of low-frequency material f.e. coming from a bass guitar. The 250 ohms version sounds more smooth and voluminous and can be used for mixing situations within the studio to analyse the whole mix." For me it they would be used for at home practice and at rehearsals through a headphone splitter(electric drums, one guitar, bass and vocals in the mix) when my band switces to "stealth mode" in order to rehearse after bedtime. Any opinions?
