I'm reaching out to gather more info about your headsets, particularly ones that come with a transmitter and receiver. I'm keen to understand the pricing options available, as well as any additional features or variations that you might offer. Could you please provide a detailed breakdown of the costs, including any package deals or bulk pricing available? I'm also interested in learning about the accessories that accompany the headsets and how they might enhance usability. Looking forward to your prompt response!
