Most built-in microphones for cameras produce less than stellar outputs. For people wanting to upgrade but don’t care to spend too much, the Azden SMX-10 is a welcome solution. It’s a small mic that’s ideal for consumer handheld cameras, measuring 7” in length with a 3/4" diameter. The SMX-10 is powered by one AAA battery that can last up to 400 hours according to the manufacturer. The reviewer tested the unit and, true enough, it did perform very well. With its low price and notable performance, the reviewer recommends the Azden SMX-10 for those wanting cleaner and more polished recordings.
