The Shure ULXD2/KSM9 is by far the best wireless microphone overall, but it comes at a hefty cost. For the average person, a microphone of this cost is not going to be necessary, but if you've got the budget for it & your focus is on quality above all else, this might be the one for you.

Shure ULXD2/KSM9 Handheld Wireless Microphone

The ULXD2 is probably my favorite wireless transmitter, using AES 256-bit encryption for secure audio transmission & a whole other range of features. The proprietary Shure Gain Ranging optimizes the dynamic range, removing the need for transmitter gain adjustments, saving you many headaches.

The Shure ULXD2/KSM9 uses the Shure SB900A lithium-ion rechargeable battery pack, which boasts a high 12-hour battery life, with digital metering on the mic! The transmitter mute mode takes an on/off button and changes it to a mute button, which has the same effect while keeping the RF channel presence.

The last feature that I find outstanding is the backlit LCD display. The navigation menu & controls are among some of the most advanced in a wireless microphone. Hands down the best cordless microphone on this list.
