孟加拉采购需求：联络中心耳机、无线耳机、带麦克风的降噪耳机、USB 耳机、呼叫中心耳机、办公耳机

I'm interested in obtaining a specific model of USB headphones and a webcam for our upcoming projects. We're looking for products that offer high-quality audio and video performance, as these will be used for virtual meetings and online training sessions. It's essential that the items are compatible with multiple devices and user-friendly, especially for those who may not be tech-savvy. Additionally, could you provide details on the pricing, availability, and lead time for these products? I'm also keen to know about any bulk purchase discounts, warranty options, and after-sales support you might offer. This information will help us make a well-informed decision moving forward. Looking forward to your prompt response!
