Query: Stunningly BAD design and function - avoid at all costs

I bought this for watching TV late at night. Any of these 3 problems would have made me return it. But 3 out of 3?! Wow, what a bad product. What you will get if you buy this:1) a volume level that (at max) is barely audible. No way to adjust the levels, all you can do is max out the TV volume, but not enough to hear.2) a prominent electronic hum that never stops.3) a charging base that is cheap and poorly designed, so that it is hard to keep the headphones on the electrical contacts to get them charged.Really, save yourself frustration, just try another product.
