What makes AKM different ?

There are many audio ICs other than Asahi Kasei Microdevices (AKM) around the world. So which IC should be selected?
One of the important factors is the sense of security that cannot be offered only from the specifications in the data sheet when customers are examining a product. 
Here, we will introduce the reasons why AKM audio ICs are so popular.

True Wireless Stereo (TWS)

The market loves True Wireless Stereo (TWS) products. It's great to be able to listen to music and watch video wherever you are, but why stop there?
Why not add Internet-enabled voice assistants, or even health care features to your favorite portable audio devices?
The demand for multi-functional TWS products requires an ever-shrinking form factor and ever-decreasing power consumption for longer battery life.
This content introduces our solution for TWS.
