About
Parasound
In the complicated landscape of audio, many companies put stratospheric price tags on great performance. Our mission couldn't be more different. Simply put, we offer the most performance for the money by finding the sweetest spot between price and diminishing returns. We've all been on the consumer side: music lovers, musicians, and audio enthusiasts looking for top-tier sound without breaking the bank.
Everything we do at Parasound is customer-centric because that's how we define value. Most of our customers don't have trust funds and have to work for their money — so we give them their money's worth and then some. Every time another expert compares our product to equipment that costs three times as much, we have succeeded.
