[Elecraft] Good 'Phones or 'Buds for KX-1?

[J. Coote]

I realized that I'm going to need some good earbuds or small phones for the
KX-1 I'm currently building.
I had in mind the following specs:
1.	Covers the ear (phones) or lays in the ear (buds), not ear plugs.
2.	Good sensitivity/volume output for use in noisy sites.
3.	Small size to fit Pelican or similar case with KX-1 and accessories, if
phones- folds up.
4.	Clean output- does not distort CW notes in 500-800 Hz
5.	Roll off-   (optional) rolls off useless noise/hiss above and below CW
audio and voiceband

Suggestions?

Thanks
Jay
