Hey I've had an Astro A50 for the last 2 months. Unfortunately, the Headset died yesterday. Now I'm interested in what are the differences of the A50 and the A40 TR. The cable doesn't bother me. But do they use the same sound drivers? Is the A40 just an A50 with wires? If so, I would buy an A40TR instead. Kind Regards, Nordik.
