How to evaluate earbud specs?..

post #1 of 4
Thread Starter 
I know most people don't pay attention to them, but I try to. I was wondering though, as an example, I've listed three pairs of different specs, what I need to know is, which pair would give better sound quality. Some have told me that the larger the driver size in the unit the better the sound, but I've also been told it's impedance. Can someone help me on this?..-confused-..I know that the human hearing range is in the 20hz to 20,000khz range (correct me if I'm mistaken), so is 17-23 khz a good range, meaning that the sound would be heard clearer with less distortion and not off into a distance?..

Driver Unit: 15mm
Impedance: 32Ω
Sensitivity: 105dB/1mW(S.P.L at 1KHz)
Frequency response 17-23kHz

Driver Unit: 9mm
Impedance: 32Ω
Sensitivity: 107dB/1mW(S.P.L at 1KHz)
Frequency response: 17-23kHz

Driver Size: 10 mm
Magnet Type: 3.5 x 1.5 mm NdFeB
Frequency Range: 30 Hz ~ 20 KHz
Impedance: 16 ohms +/-15%
Max Input Power: 10 mW
Output Sensitivity: 112 db +/- 3 db at 1 KHz

You can not determine the SQ by simply looking at the spec. The only way to determine the SQ is by your ears (hence why so many of us don't pay too much attention to spec) - If it sounds good, it is good .

About all you can hope to get from specs is whether or not the phones will be easy for your rig to drive taking their impedance and sensitivity into account. Beyond that, they don't mean all the much.

i've never taken numbers or charts seriously when it comes to headphone equipment
