Shure SM58 is Industry Standard Mic - Beware of Fakes!
3 of 3 people found this review helpful.
The SHURE SM-58 is the industry standard workhorse. Every pro musician, sound engineer and DJ should have at least one of these in their toolbox.
Unfortunately, since SHURE's SM58 is so popular, it is commonly counterfeited and many are sold to unsuspecting buyers. Buyer beware of new SM58 mics offered for sale below $99 (the current Shure minimum advertised price). More often than not, these are not authentic. Be especially careful of microphones shipping from the following countries: China, Hong Kong, Singapore and Japan. Sellers will often list 1-day auctions with low starting prices or buy-it-now options. Another common scam is for counterfeiters to sell "slightly used" or "like new" mics as a justification for the low pricing.
Here are a few keys to identifying an authentic SHURE SM58:
Packaging: Counterfeits have convincing packaging! Make sure the label matches the mic. The SM58LC is does not have an on/off switch and does not include a cord (it does include a Velcro cable tie). The SM85S has an on/off switch. If the label says it is an SM58LC & also lists on/off switch on feature list (regardless of what is in the box), it is a fake. The SM58-CN is the only SM58 mic that includes the cable. The authentic SHURE mics do not have stickers all over the box or mic that say "genuine Shure." The mic clip on an authentic SM58 only has the SHURE logo on the side of the mic clip; fakes may have writing on the underside that indicated it was manufactured by Shure in Mexico.
Weight: authentic mic feels sturdy. Imitations are often lighter weight.
XLR3 connector: authentic has each pin labeled 1, 2, 3; it also has a Shure logo on the XLR3 connector. DC resistance between pins 2 & 3 should be ~17.8 ohms. Imitations may be missing pin labels, Shure labels, etc. One fake I tested had a DC resistance of 0.2 ohms between pins 1 & 3 and an open circuit between pins 2 & 3. Yikes!
SM58 logo: On the SM58, underneath the windscreen, there's a printed "Shure SM58" logo. A sticker wrapped around the mic is a counterfeit.
Windscreen: bottom of the metal windscreen has a rounded edge. Many fakes have a flat lip.
Mic element: Fake SM58 commonly has a "CAUTION" sticker wrapped around the mic head. This sticker is not on authentic microphones.
Circuit board under mic element: authentic mics have a red quality control stamp. This stamp is often missing on fakes.
Wire color: The wires that connect the mic element to the transformer are yellow and green. If they are any other color, it is either a repaired mic or a fake. Some fakes use the correct wire color.
Included accessories: authentic includes the following: mic, mic clip, zippered pouch with SHURE embossed surface, Velcro cable tie with SHURE logo, SHURE bumper sticker. Many fakes are very good at replicating the box, paperwork, etc.
Buyer beware! Good Luck!
