- The TG-X 930 achieves neutral transmission of even the subtlest vocal nuances while a slight treble boost ensures an open and accurate sound without ever being overbearing. The stainless steel basket with multilayer gauze and additional inner basket, already used in the interchangeable microphone capsules of the Opus 900 wireless series, provides excellent protection against pop sounds. It is not only easy to clean, but also significantly improves rear-attenuation and hence increases feedback reduction.
