Sony’s total commitment

“With Sony, the whole company is involved in making a single product. Many people’s opinions, even on small details, are consulted before reaching a conclusion based on the data. It’s the expression of each person’s confidence and sense of responsibility in bearing the Sony brand.”

Headphones, an expression of style

“For example, glasses are a tool that aid eyesight, but they are also a part of that person’s personality. Furthermore, people who wear glasses look for glasses that suit their face and they create their own look. I think it would be nice if headphones were on that kind of level.”

The best fit for you

“The shapes of people’s ears are very different. It isn’t simply that the size of the ear holes, but the direction and angle of the hole varies between the right ear and the left ear. There is an endless variety of ear shapes. If the earpiece is loose and air leaks, then you aren’t likely to get the sound quality that the engineer is aiming for. You will get better sound quality if you choose an earpiece that fits your ears.”

Tomohiro Matsuo, Headphone Designer & Fifth Master Ear Molder
