By comparison my Etymotic E6's are rated at 48Ω but their E6i, designed specifically for "iPods" is also rated at 16Ω—the lower impedance helps eek a little more oomph out of the low-powered amplifiers in portable electronics—not a bad thing if that's the device you're driving them with. Bottom line, try increasing the impedance, or use different "cans" with your Macbook. | |

Fixed multiple misspellings of "impedance" before someone pulls my card

| Mar 6, 2012 at 22:10 | comment | added | Tuesday | I'm using the MEElectronics M9-BK (quite cheap, but quite good). Is there any kind of software method of increasing impedance? As far as I can tell, it would need to be hardware, but I wouldn't mind being pleasantly surprised. ;) | |

Added one more potential solution
