Thanks to the provided universal mount, the Stylus 305 can also be mounted on standard half-inch tonearms. This allows it to be used on a wider variety of turntables.

Ortofon Quality Manufacturing

Like all Ortofon products, the Stylus 305 benefits from high-precision craftsmanship at the brand’s factory in Denmark. Each diamond is meticulously inspected and tested before shipping to ensure optimal performance. The natural diamond tip is hand-cut and polished with the utmost care.
