印度采购需求：蓝牙音箱、游戏音箱、KTV音响、多媒体音箱、户外音箱、派对音箱

I'm looking for high-quality karaoke speakers that can deliver excellent sound performance for both home and professional use. It would be great if you could provide details about the various options available, including specifications like power output, frequency response, and connectivity features. I'm particularly interested in models that are lightweight and portable, as well as those that can connect via Bluetooth for added convenience. Additionally, I'd like to understand your pricing structure, including any bulk order discounts or shipping options. Please also share any relevant certifications or quality standards your products meet, as well as estimated lead times for order fulfillment. If you have any promotional materials or product catalogs, that would be really helpful too. Looking forward to your prompt response!
