摘要:
Provided is a method of efficiently producing an epoxy compound from an allyl ether having an aromatic ring under mild conditions by using hydrogen peroxide as an oxidizing agent without using an organic solvent. The method of producing an epoxy compound comprises reacting an allyl ether having an aromatic ring with hydrogen peroxide to epoxidize a carbon-carbon double bond of an allyl group to thereby produce a corresponding epoxy compound having an aromatic ring, wherein water only is used as a solvent without using an organic solvent, and a tungsten compound, and a tertiary amine and/or a quaternary ammonium salt, are used as a reaction catalyst.

A headphone set has a housing to contain a speaker unit, with a sound emitting surface through which sounds given off by the speaker unit are emitted out, and an ear pad attached to the housing to surround the sound emitting surface. The ear pad has a protruding member and an arc-like member sticking out in opposite directions. The degree of sticking out for the arc-like member is smaller than the degree of sticking out for the protruding member. The protruding member has an inner space interposed between a top section and an opposing bottom section closer than the top section to the sound emitting section. The arc-like member has a top section and an opposing bottom section closer than the top section to the sound emitting surface. The top section of the protruding member is positioned farther than that of the arc-like member from the sound emitting surface.
