looking to score some cheack XB-700's I noticed Sony just unveiled their new MDR-XB1000   More info to come. Would love to see how these compare to other bass heavy phones.  Based on the difference between xb300 500 and 700 I expect the 1000 to sound great.

Hello and thanks for reading.  I got a p-51 but no charger and I am wondering how to charge it.   Is there a replaceable battery in it?   Can I use any 5VDC power supply or what specs should I be looking for in a power supply.   Any help would be appreciated. Thanks.
