I'm reaching out to inquire if your factory produces microphones with a 9.7mm diameter. We're currently exploring options for high-quality audio equipment and are particularly interested in this specific size. If you do manufacture this type of mic, could you please provide more details regarding available models, specifications, and pricing? We're looking to understand your offerings better to see if they align with our needs. Thanks!
