During the past year, Respeaker Mic Array V2.0  has been sold out for more than 10K units in the format of the development board. Customers keep requesting a complete device with an enclosure, which is challenging for them to design it, considering the acoustic principles.   

 And here Seeed provides the answer with ReSpeaker USB Mic Array:

• An out-of-box device with a well-designed acoustic structure brings the flexibility for the customer to build in their solution. 
• Mold injected enclosure available, saves the time to go to the market and the mold cost.
