And "push-to-not-hear" when you don't want to hear them explaining for the millionth time how to fasten your safety belt.

I would think the "clear" phones could be better because they're less obvious. Both are obviously better than the Bose.

Do any of you know why the rule to turn off electronic devices at take-off and landing actually exists?

I seem to remember someone telling me that it was because with laptops, they could become projecticles and injure passengers (during the more dicey periods of flight) but this doesn't make much sense to me. It sounds like something that a bunch of lawyers working for the airline created to prevent the airline being sued. (I know that's the reason for the safety belt announcement)

All electronic devices generate electro-magnetic interference. Some very little; others a lot. The concern is that the interference could interfere with electronic aircraft systems, which is most critical during take-off and landing.

The electronic systems on the aircraft (e.g., aircraft audio system) have been tested for interference, but your personal device obviously has not been tested by the airline or FAA.

Under FAA regs, an electronic device can only be used during take-off and landing if it is certified as not producing interfering levels of electro-magnetic interference.

I posted a relatively good deal on E2Cs (2 pairs for $110) in SPAM

Do the triple-flange sleeves fit the E2C? The Shure website states the following:


Triple-Flange Sleeves

These reusable, silicone sleeves form a tighter seal than flex sleeves while holding the earphones firmly in place. Triple-flange sleeves provided as part of the Fit Kit with E5c earphones only.
