UwayKey Amplifiers Editorial Review
The Whuzi Mini Bluetooth Amplifier has been well received by customers who were impressed by its power output and sound quality for such a tiny amp. It is compact, easy to assemble and comes with a laser cut protective plates and screwdriver. While some felt that the Bluetooth connection range could have been better, others used a homemade antenna to improve it. Customers recommended using an old laptop brick and higher voltages for best performance. The amp was paired with various speakers, from 5in bookshelf speakers to huge old 80s style stereo speakers, and overall, customers were pleased with the sound quality for the price. However, some recommended installing a separate power switch to conserve battery life when using as a portable Bluetooth speaker. Finally, a few customers received units without heat sinks, which could be a concern when using for prolonged periods at high volume.
