You can select between a genuine Shure N111E or the Radio Shack version R16X also made by Shure in the dropdown menu. Both have the same technical specs in the literature. The Black guard in the N111E and the white guard in the R16X are believed simply to represent different marketing channels of the exact same needle.

• Replaces: SHURE N111E needle
• Used In: SHURE M111E cartridge
• Original needle color is usually: BLACK
• NOTE: Because this needle is designed for use specifically with SHURE cartridges, it can be found in numerous brands of turntables. In some cases the cartridges for this needle may be original equipment supplied with a new turntable, but was also likely to have been selected at time of sale to complete a turntable sold without a cartridge or later as an upgrade to the original cartridge supplied by the turntable manufacturer. This needle should be matched primarily to the SHURE cartridge type not necessarily the turntable.
