Sumiko Oyster Moving Magnet Phono Cartridge

What You Need to Know

The Cartridge That Started It All

The Sumiko Oyster Moving Magnet Phono Cartridge is the namesake of Sumiko’s entire Oyster Series—a rugged, musical, and famously reliable design that has introduced generations of listeners to better vinyl sound. Handcrafted in Japan, the Oyster is built to deliver satisfying, fatigue-free playback day in and day out.

If you’re replacing a worn or broken stock cartridge, or setting up a classic turntable, the Oyster is a proven, affordable solution.

Durable Spherical Stylus

The Oyster uses a 0.7 mil spherical diamond stylus—a forgiving profile that’s easy to set up, gentle on records in less-than-perfect condition, and highly resistant to wear. It’s an ideal choice for casual listening, well-loved record collections, and DJ-adjacent duty.

Strong Output for Any System

With a robust 5.0mV output, the Oyster drives any standard MM phono input with ease—including the modest built-in phono stages found in vintage receivers and all-in-one systems. Its smooth, warm balance makes every record enjoyable.

Confident, Secure Tracking

The Oyster’s slightly higher recommended tracking force of 2.3 grams keeps the stylus planted securely in the groove, delivering stable, skip-resistant playback even on turntables with basic tonearms.

User-Replaceable Stylus

When the time comes, the Oyster’s stylus replaces in seconds with no tools—just snap in a genuine Sumiko RS Oyster replacement and keep the music playing.

Handcrafted in Japan

Every Sumiko Oyster is individually assembled, adjusted, and tested by experienced cartridge craftsmen in Yokohama, Japan.

Building Your System

The Oyster is an excellent match for entry-level, vintage, and all-in-one turntables with any standard MM phono input.

It’s the easy, dependable choice when you want good sound without fuss.
