just got them this morning and started by not updating the firmware. I did immediately use the equalizer to import QR from DMS (LTT LABS). As an old man with tinnitus, I can honestly say these are my new favorite way to listen to music. Extremely comfortable to wear even with glasses even after more than 3 hours. Transparency mode allows me to hear my wife and surroundings very clearly.
Only issue I have noticed is a left channel drop on my LG tv in my bedroom. No issues with big LG in my living room though so it may be a minor issue. All other devices have come through very clearly with no interference, even with multiple people listening to different devices simultaneously. Over all I am extremely happy with my purchase. 😎
