This may seem slightly silly, but is there any harm in connecting a set of powered/wireless headphones (such as the Wireless Momentums, or Plantronics Backbeat Pro) to an amplifier? What actually happens? 
 
Any help much appreciated.

I asked the same question a few weeks ago. Here is a link to the thread:

Just a side note, any Bluetooth headphones you have were made to be used wirelessly, therefore they will sound better wireless.

There is no problem unless you turn it up loud, you won't kill your headphones you'll just increase the gain, and it will sound bad.

If it even has a cable that can make it work that way, then you'll send a louder (ie higher voltage) signal due to the amplified signal. If you turn down the volume on the built in amp, then no harm. Otherwise, there isn't any benefit because the amplifier that still drives the headphone will be the built-in amplifier, so apart from getting a much louder signal (which assuming it wasn't getting an EQ effect from the amp or the interaction between the first amp and the internal amp), it's the capabilities of that amplifier that still matters, in which case the drivers on these are selected with high sensitivity to begin with thus even those that can bypass the internal amp (ex so as not to use up the charge) barely benefit from a better amplifier because even the built-in amp barely gets to a point where it's already piling on distortion.
 
Basically I'm saying that audio amplifiers do not work like fictional energy weapons where a giant robot can connect his two rifles in series so the output rises exponentially allowing the giant robot to either punch through a battleship with an energy shield.

That's parallel. I actually linked an example there in that link - the ZGMF-X20A Strike Freedom, OS Generation Unsubdued Nuclear Drive Assault Module (GUNDAM), with the relevant weapon system being the MA-M21KF high output energy rifles.

Actually it's a joke, or that's what I meant for it to be. XD

I know it is, I'm just clarifying that the use of two amps in this case is in series and that that's the kind of example I used, and the photos of a seemingly unrelated thing similarly posted in jest regarding how electronics are mostly misunderstood. Kind of like how portable rigs during the iPod era got ridiculously large, not simply because of an iPod, iPod-compatible DAC and one amp, but Ive seen a few that used two amps in series.
