Query: Great Headset, Battery & Charging Problems

I used this product and was impressed with the volume. However, the connection for the charger is iffy at best. Mine lasted about two months. Now the battery will not hold a charge. I tried all the memory reduction tricks I know to make this battery last, but to no avail. The price is right, the volume is good, the power button is difficult to use and the battery is gone after a short while. If the power supply was better, I'd buy another one. For now, it's back to the wired headset.
