Looks well made, connected to my phone with no problems. Plenty loud enough. One component damaged but device still working. My only concern is the range, I can barely get across the room without the signal starting to break up. Looking at the PCB I can see that there is a ground plane under the antenna track. Now all guide lines I have seen state that this area must be kept clear of all tracks. This is a design fault. So I'm not surprised about the range. This could be resolved by replacing the PCB track antenna with a short 1/4 wavelength piece of wire.

Brandon Holt Have you tried this fix as of yet? I am very curious how much improvement can be achieved on this board.
