Even with nothing between the adapter and the source, the effective range was 15 to 20 feet. To make sure it wasn't a JBL Flip speaker, I connected the speaker to my iPhone via Bluetooth and had someone walk about 45 feet across the street and the music played and didn't skip a second and there was no sign of it that this was near the maximum range. The computer in question was one I built for my mother. It runs on Windows 7 64-bit and all drivers and firmware have been installed and/or updated for the StarTech Bluetooth adapter.
