SO I HAVE A HARMAN KARDON RECEIVER THAT I LIKE PRETTY WELL, but it’s several years old and doesn’t have any form of wireless connectivity. But for $24.95 I got this add-on bluetooth receiver that pairs easily with my phone or computer, letting me play music from iTunes, Amazon, or any streaming service. It set up easily, paired with the push of a button, and seems to work flawlessly. My only complaint is that it will only pair with one device; when paired with my computer, it forgets my phone. But for under 25 bucks, not bad.
