Replacing triple a batteries

[SykoXhadow]

Hi everyone! I am newish to wiring electronics. I have a set of wireless Turtle beaches that run on 2 triple a batteries. They devour batteries faster than i can charge them. I would like to power them with a standard USB cord but I have no idea how to safely do this. I really don't want to fry a $150 headset. Any help would be greatly appreciated.
P. S. I have some experience with electronic repairs but I don't really know much about circuits outside of splicing.

Welcome to EP!
How much current does the headset require?

 

[SykoXhadow]

It runs on 2 AAA and my rechargeables say 1.2 v/800mAh but a regular alkaline triple is 1.5

Turtle Beach headphones work perfectly off USB.
No problem.

You don't think 5v would be too much? I know it's only 2 more volts but i just want to be sure

Quite possibly....
But my son's have been working through PS3 And PS4. So over 3 years without a problem.

His was powered by triple a's? Just want to be extra sure. Thanks for the help.

Be careful Martin, there might well be different models, some of which run off USB and others off batteries.

To the OP:

The correct way to do this is to use a 3V regulator between the 5V USB port and the headphones. It is a fairly simple circuit. Do you have any experience with building circuits on perfboard?

No I don't. I'm sure i could handle the project, though. I do repair my electronics and I've wired lights into my car so wiring isn't an issue. I just don't have knowledge about resistors and more technical things in circuits.

The other solution is to get a 3V wall wart. No assembly required, just connecting 2 wires to the battery holder.

Good point Bob. My son's old pair did have two AAA's. His new ones (2 years) have 2 AAA's too. So I was blindly leading the blind as per usual!.
But both the headphones sets have been working without a problem ever since.
So I will say to the OP, follow Bob's advice and stick a 3 volt regulator in-line.

Thanks for the help guys! Will check into getting the regulator. Hopefully some place sells it locally
