Ortofon OM Q-bert and Technics headshells. Set of 2, tested and working. There is a small chip in the third photo, but it does not affect the operation or sound. Please refrain from purchasing if you are sensitive to used items. Quoted from the official website: Battle DJ specifications with high output and durability, supervised by DJ Qbert. DJ Qbert himself was involved in the development at Ortofon A/S Denmark, and succeeded in minimizing needle skipping during scratching and back-cueing. And it achieves "an amazing 11mV," the highest output in the world for DJ cartridges and MM cartridges. This specification ensures reliable input even with Phono, which has a lower output signal than Line. It's an ultra-powerful sound that can be obtained because of the "amazing output." ● Output voltage: 11mV ● Channel separation: 22dB (@1kHz) ● Frequency range (-3dB): 20～18,000Hz ● Stylus: Spherical ● Recommended tracking force: 3g ● Weight: 5g ● JAN: 5705796020748 ● Replacement needle Stylus Q.Bert ● JAN: 5705796140309 Ortofon DJ Q-Bert OM Needle Set ISP
