Hello everyone. I am on the road quite a bit and take business calls from my LG Thrill. I was using a bluetooth headset before but decided to switch to a corded headset so that I wouldn't have to worry about charging the bluetooth, pairing, etc. I just got the Plantronics M175 headset (which I have owned in the past and has excellent sound quality). The headset has a 2.5 mm connector so I got a 2.5mm -> 3.5 mm adaptor from ebay. Everything works great except: when I'm using my Thrill, the inline mute button on the headset does not work! Even if I turn the headset on mute, people on the other end can still hear me. Note, the mute button on the phone still works but it's a pain to operate the touch screen while driving to turn mute on and off (one of the reasons I got the Plantronics was because of the inline mute and volume control built into the cord of the headset). However, when i use the Plantronics headset at home with my cordless phone which has a 2.5 mm jack, the mute button on the headset works perfectly! So my question is this: is the mute function on the headset not working because of the adaptor (2.5 mm - > 3.5 mm) or is this an LG Thrill issue where it does not for some reason recognize the mute functionality on wired headsets. Thanks in advance!
