Audible noise from device.

This attachment is awesome. The adapter raises the possibility of the Headphones. Audio sounds great coming from the adapter, but the volume is not as loud as it is wired. One big con is their is some type of sound that the adapter makes. It sounds like there is a bit of frequency. Another con of the adapter is the price. The way the buttons click and the adapter feel is not what you would expect from something that cost $50. If this product was between $30-40 it would be fair. Another con is the batter life is on the short range. It is not terrible but if it could last 2hrs longer it would be perfect.
