The Shure Microflex® MX153 is a professional subminiature earset microphone ideal for speech and other applications requiring low-profile discreet placement where improved gain before feedback over lavalier microphones is desired. Delivering exceptional speech clarity, the MX153 is ideal for corporate presentations, houses of worship, A/V conferencing and live sound reinforcement. Additionally, CommShield® Technology offers superior RF immunity from cellular devices and digital bodypack transmitters. Available in three color options and direct TA4F connectivity to Shure bodypacks, the MX153 provides outstanding clarity in an extremely comfortable, over the ear design.

The furnished windscreen provides plosive and wind protection.
When connecting the microphone to anything other than a Shure wireless bodypack, make sure the device provides a regulated +5 V DC (130 µA minimum).
To connect the MX153 earset to an XLR microphone input, use the RK100PK preamplifier (see Optional Accessories).
The RK100PK preamplifier requires phantom power and performs best with a 48 Vdc supply (IEC-61938). However, it will operate with slightly decreased headroom and sensitivity with supplies as low as 11 Vdc.
Most modern mixers provide phantom power. You must use a balanced microphone cable: XLR-to-XLR or XLR-to-TRS.
This microphone features CommShield® Technology for superior RF filtering. For best results in hostile RF environments, always use the RK100PK preamp (see Optional Accessories).
Fit the earset over the ear with the ear support piece placed behind the earlobe. The wire extends over the ear to the tip of the mouth. Adjust the earset with small bends. Do not bend the boom arm beyond 20°.
