Prologue 14L mics are low impedance dynamics. The wiring can accommodate either balanced or unbalanced use. The 14L is appreciably better than the rest of the range in subjective terms. Its frequency response reaches up to 13kHz, only 2kHz lower than the SM58, (which costs roughly four times as much) though it has a high frequency dip just above the presence peak that characterises all the dynamic mics in the Prologue range. This microphone is better suited to more serious vocal use and can be used to achieve results of a very high standard in the small studio. It also has a lockable on/off switch.
In conclusion, these mics offer good value for money. Retailing for only a fraction of the price of original Shure microphones, the only indication of reduction in quality is slight tonal loss at the top end, slight handling noise and a slightly coloured tonality due to the less than flat response curves. They seem very rugged and are easy to service. Definitely a range not to be overlooked if finances are tight. Useful for work with vocals, electric guitars and some mid-range percussion, but unsuitable for use with bass instruments where punch is required.
