How does impedance effect headphones? Answered
I've decided that I want to buy Beyerdynamic DT 990 Pro Headphones but they come in three different impedances (and unimportant aesthetic variations). It comes in 32 ohms ($349), 250 ohms ($260), and 600 ohms ($369). I've already looked on the internet and it basically said that impedance does not effect sound quality but the MSRP on these differ up to 100+ dollars between models, what gives? I will mostly be driving these headphones off a laptop and occasionally an ipod.
