Plugging jack into devices -- or not -- for just using noise cancellation
If I just want to tune out my obnoxious upstairs neighbors and not listen to any music, can I simply turn on the noise canceling earbuds without plugging them into my iPhone (or any other device)? Will the active noise cancellation still work if not plugged into a music player or other device? My primary purpose will be noise cancellation (not music listening) and I want something I can comfortably wear around the house -- without always needing to be tethered to my iPhone -- while I count the months until my lease expires. Thanks. ... and never rent a downstairs apartment.
