Looking for some advice..

post #1 of 6
Thread Starter 

I just received my ~~Audio Technica ATH-ANC23 in-ear phones after reading a lot of positive reviews on them, Got them to replace a pair of scullcandy inkd  I"ve been using for about 2 yrs.  I am not a Headphone authority or an Audio expert in any way-Hence the reason why I am here,,As ordinary as the Skullcandys are, They worked fine for me-even had them hooked to a FIIO E5 Amp for some better "kick if you will" sound. My problem is when I plugged in the ANC-23 into the little Fiio amp, they sound down right horrible. Very low in volume, When I try to raise the volume I get a lot of distortion-static. I also tried them without the amp, sounded a little cleaner but still low volume. The scullcandys sound way better than these Audio Technica ,  which is a problem because that's like comparing a volkswagon to a Ferrari. Can somebody tell me why these headphones aren't working like they should? Is the Fiio E5 not strong enough to push these? Is the Impedance an issue? (Sculls are  16 ohms- ANC23 are 32 ohms) I have them on an Optimus F3 with Poweramp if that means anything. Any advice would be helpful,, Also considering if the ~~Klipsch Image S4 would be a better alternative..Thank you gentleman.

They are active noise cancelling earphones.

Yes they are, Can that be the problem?

Noise cancelling headphones tend to not sound as good. Also you're paying partly for the noise cancelling so don't expect quality close to other earphones within the same price range. You should try normal audio technica earphones. I really don't see the point of getting noise cancelling IEMs since they passively cancel most of the noise already.

Does impedance have anything to do with how "loud"  a Headphone can go?

That's sort of like asking does power have more voltage or current?  Strictly speaking, efficiency governs how loud a headphone can go with a given amount of power.  However, impedance dictates how much of the power from an amplifier is successfully applied to the headphone.


A headphone wants power to produce sound.  However, the impedance of the headphones determines the ratio of voltage to current needed to result in that power (Power = Voltage X Current).  Given the same efficiency (or sensitivity), a higher impedance headphone will need more voltage to use a given amount of power than a lower impedance headphone, which will need more current for the same amount of power.


Most amplifiers tend to favor one or the other: voltage (tube amps) or current (solid-state).  Of course, there are examples of exceptions to this generalization - solid-state amps that supply lots of voltage, or tube amps that supply lots of current.  That is not the norm, however.
