Optimal fit and sound reproduction

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.

For more than 50 years, Ortofon has been designing and manufacturing Moving Magnet cartridges. Along with our well-regarded Moving Coil cartridges, Moving Magnet models have established a good reputation among music lovers and Hi-Fi enthusiasts the world over.

The new Ortofon OM 5 series encompasses three basic cartridges: OM 5S, OM 5E and Super OM 5E.

• The series is the lowest-mass range of moving magnet cartridges offered by Ortofon.
• The OM cartridges bodies have been designed to provide easy mounting and alignment on both top mount and bottom mount headshells.
• The OM 5 Series provides excellent compatibility when used in an assortment of playback systems and with a wide variety of phono preamps.
