I came across your listing for headsets and I'm curious to know more about them. At Lexound, we specialize in producing high-quality headsets designed specifically for call centers and office environments. Could you let me know if these headsets are proprietary to your brand? Additionally, I'd appreciate any info on specifications, pricing, and minimum order quantities. Looking forward to your response!
