What is the difference between the Aria Pro and the Pro 2 ?

Apart from all the features Aria Pro offers including dual link support, Aria Pro 2 boasts about its advanced microphone array noise cancellation technology so you can use it in a noisy environment. It cancels up to 99% of the environment noise so you can work from a noisy airport or the food court of a busy shopping mall. Even better, from time to time, we will release firmware updates with enhanced calling features to meet the needs of using in different scenarios. 

It also has Sidetone feature so you can hear yourself speak. Instead of talking loud, you can whisper to the microphone and others still can hear you well.

The cons part of Pro 2 is that it doesn't support Faststream codec. If you want to play games and talk on discord, or listen to music and take the conference call at the same time, the sound will become mono even if you use a dongle that supports Faststream codec.
