Only a "Stereo" system in "Stereo" setting will output in both ears. "Microphone is intermittent. There is a delay in communicating." Check first that the squelch on the plane's system is tuned properly to match the noise level. It needs to be adjusted lower if it's not transmitting the first words. Does the headset fit comfortably over glasses? Yes, the headset fits comfortably over glasses. Does the headset require batteries, and if so, how long do they last? The headset does NOT require batteries. It features passive noise cancellation through high-density acoustic foam earcups and gel ear seals.
