I was wondering if the Shure PA235 Level Attenuator is neccessary for both the Shure E3 as well as the E3c or does it only apply to the E3 model? I have the white E3c which has no volume control on it and I don't want to be on a flight and find out then that I need the PA235 if the lowest level of the seat headphone output is still too loud. Can anyone advise further please?
The Shure E3 is, AFAIK, exactly the same as the E3c with the exception that the E3c has the more iPod friendly white color. Here is a review of the E3 where the reviewer states that the E3 and E3c are the same. So, the level attenuator applies to both models. Having used the E3 on a plane before, it is almost a necessity to have the attenuator if you want to use them to listen to the inflight music/movie. The output is already increased to account for the ambient noise, and can be damaging (and painful) without the attenuation.
