I'm thinking of picking up some 600ohm earbuds, just need to figure out how I'm going to drive them. haha
Has anyone tried any?
The most I've tried is a few 300 ohm buds, yeah they do need amping, but most desktop amps should be powerful enough. Though I realize that actually the sensitivity is the more important component in drivability, the impedance is of a lesser importance for drivability, and maybe another variable is the driver type.
Maybe some physics experts can advise, but I've tried a few IEMs that have sub 100 dB/MW sensitivity, and they were quite a pain to drive eg Final Audio E5000 - Sensitivity: 93dB, but impedance 14Ω, and let's not mention some planars like the Tin P1. On paper the E5000's 14 ohm impedance looks like a pushover to drive, but the low sensitivity is probably the one that is the power hungry component.
Buds are mostly DD, so maybe less variable in driver types, but even among DD they do use different materials, assuming they ain't marketing gimmicks.
