I have been looking but I haven't come close. I had a set of headphones that my wife could plug her IPOD-like player into. They were like earmuffs (blocked outside noise) with a battery powered amp in them. She used them while mowing the grass, etc. I think I paid around $30 for something similar in Harbor Freight but they no longer sell them.

I'm looking for something that looks like this:



Not this:

 

What terms are you searching?

Edit: This sort of thing is popping up, not sure if this fits your needs or not. Rechargeable internal battery. Pretty good reviews.

My last search was:

headset mp3 batteries -tablet -wireless

 

Were they noise-cancelling headphones? All the ones I've seen with a battery were for the purpose of outside noise reduction.

I'm guessing the ones you are talking about have the in-line battery like this?

 

No, the battery was for amplification. The ones she has now (the broken ones) have a built in AM/FM radio. I think I paid $40 for them but I should be able to get something cheaper. The lack of a radio would be a good thing (would hopefully mean that the manufacturing expenses went into a quality amp).

 

Like yay?

I think it'll be hard to find a set that is powered, no am/fm an not for noise cancelling. There are amplified headsets for gaming though...but I think most of those use USB for power and not battery.

Edit- Found a set...though they are $60
