Hey So I'm here to talk about ways to connect things to an A50 or A40 headset. Things like powered high end subwoofers using optical audio cables. I'm talking without using an auto audio receiver. Just plugging into a wall and connecting to the mixamp. Also a dongle to use your phone and still hear it ring see if you're playing something with loud audio, while you have headset on you will miss the phone call or text. End goal is to play the notification or ringtone through headset. Using your Bluetooth for example. These are things that we could greatly benefit from and improve the gaming experience while multitasking and giving you that actual subwoofer feel rather than adding just bass to your ears.
