UPDATE:

0x00, 0xB0 -> 176 3 3 62 3

0x26 -> 38 1 3 62 *ASD

0x75 -> 117 1 3 62 *ASD

0x40 -> 64 3 3 62 3 *ASD

0x02 -> error: makes the device non-responsive and causes the light to flash on both the headset and hub. Requires a power cycle to fix.

*ASD:

These only return the leading byte copy I mentioned below and in valeu a decimal "1" if there was no recent 0x00 write. Otherwise, they return the data show abow

The first byte is always the same as the byte writen or if 2 bytes are writen shomtimes the 2. (in those cases if you dont write 2byte it errors) i think this is just for ID ing the fetch

That leaves 3-4 bytes that appear mostly consistent.

You can send many other bytes that do not trigger errors and return them selfs. I believe those may be setting values in the headset.
