The OM 5S is a moving magnet cartridge for general purpose application

If your tonearm has a standard headshell or a cartridge mount, then step up to optimal sound reproduction with OM’s. A glance at anyone of these cartridges will reveal Ortofon’s answer to perfect tonearm matching. Ingeniously tucked into the top of the mounting bracket is a tiny, removable weight-plate.

If your tonearm is an standard tonearm, just leave the weight-plate. If your tonearm is one of the low mass types, then simply remove the weight. The mass of your OM cartridge is now a mere 2.5 g.

The OM 5S features Spherical stylus, robust and economic solution for play back of vinyl records.
