I'm currently looking to source a specific model of headphones and would love to get more information regarding the pricing options. Could you please provide me with your competitive rates, along with any available bulk purchase discounts? Additionally, I'd appreciate details on the minimum order quantity, lead times, and any warranty or service support that comes with the headphones. If you have a product catalog or a specification sheet, that would be great too!
