The Astro A20 Gen 2 does require a dongle for wireless connectivity. The headset itself comes with a USB dongle that needs to be plugged into a compatible device in order to establish a wireless connection. This dongle is specifically designed for use with gaming consoles such as Xbox and PlayStation, as well as PC.
However, if you intend to use the Astro A20 for commuting or traveling, there are a few limitations to consider. Firstly, the headset does not have built-in Bluetooth capabilities, which means you cannot directly connect it to your phone or other Bluetooth-enabled devices. In order to use the A20 with your phone, you would need to purchase a separate Bluetooth adapter that is compatible with the USB dongle.
Using a dongle with an adapter can be quite cumbersome for on-the-go use. It adds extra bulk to your setup and may not be the most convenient option for traveling. Additionally, the Astro A20 Gen 2 is primarily designed for gaming purposes, so its features and design may not be optimized for portable use.
If you are looking for a headset specifically for commuting or traveling, there are other options available that are more suited to those needs. Wireless headphones or earbuds with built-in Bluetooth connectivity would be a more practical choice, as they eliminate the need for dongles and adapters.
While the Astro A20 Gen 2 is a great gaming headset, it is not ideal for commuting or traveling due to its lack of Bluetooth compatibility. If you do decide to use it for portable purposes, you will need to invest in a separate Bluetooth adapter to connect it to your phone or other Bluetooth-enabled devices.
