Portable usb power supply for turtle beach X12 headset.

I recently acquired a pair of X12's and they require usb power to run, I would love to be able to use them for applications outside sitting at my computer. I very little real experience with electrical power supplies, but I am almost sure that  most of the portable usb batteries that I have found put out too much for them too handle.
Here are the full specs for them;
50mm diameter speakers with neodymium magnets
Speaker Frequency Response: 20Hz - 20kHz, >120dB SPL @ 1kHz
Condenser Microphone Frequency Response: 50Hz - 15kHz
Cable length: 16 ft. (4.87m)
Weight: 6.4 oz (233g)
       In-line Amplifier
Headphone Amplifier: Stereo DC-coupled, 35mW/ch, THD <1%, Frequency Response: DC - 30kHz
Bass Boost: Variable up to +12dB@150Hz
Mic mute switch
Maximum analog input level with volume control on maximum setting: 2Vpp (700mV rms)
3.5mm plug for line input
3.5mm plug for mic output
2.5mm XBOX 360® controller input jack
USB connector for power (5VDC @ <60mA max)

"USB connector for power (5VDC @ <60mA max)" - That's the line that you need to pay attention to. Basically your power source should provide 5v, maybe a little less to be safe, and at least 60mA.
You only have to really worry about the voltage because the headphones should only draw as much current as they can handle.

Just search for "USB Charger" here on Instructables or on Google. Also most any off the self USB charger shouldn't provide more than 5v.

WHat the current rating tells you is how fast it will drain a battery. Simply divide the capacity of your chosen charger, lets say 120mAh, by the current drawn by the headphones, 60mA. 120mAh/60mA = ~2 hours of play time per charge.
