Hi,
Not science but I have been using the HF-5 (and pre-cursor) for airplane travel for the last 15 years and I love them.
I also have the much more expensive Bose NC headphones but I find the Etymotics are much better for listening to a movie on the plane.
I use the foam tips mostly.
(as the in-ears are most effective in higher frequency but the active noise cancellation is more effect in the lows, putting
the Bose OVER the HF-5s is amazingly quiet J)
BW,
Bas

Subject: Re: [AUDITORY] Noise cancellation earbuds
We evaluated the attenuation provided by Etymotic HF5 noise-isolating earphone (cost < $150) in a sound-attenuating chamber using three different ear tips provided by the manufacturer. We measured speech recognition thresholds (SRTs) using
spondee words in the sound field with both ears of the subject plugged by the ear tips. Four participants were evaluated. The eartips evaluated were the Etymotic Research ER38-15SM 3-Flange Ear tips (size small), ER38-18 Large 3-Flange Ear tips, and the ER38-14F
Standard Black Foam Ear tips. The foam ear tips provided the most attenuation, which is approximately 20 dB.
Hope this is helpful.

Hi, my sister is very easily distracted by noise, esp. in the office where she works, and she wants some suggestions for good noise cancellation earphones. She'd like to spend less $150, and is willing to get used ones. So if any of you know of some good models, and places to get them for under that amount, please let me know!
Thanks in advance,
Brian Gygi
