Extra Bass Series

Designers’ Interview

Pump up the bass

Discover the explosive, exciting and totally exhilarating XB Series headphones. Designed for those who love their music

with serious amounts of bass, it’s all about feeling the rich, deep thumping bass line - without crushing the mids and highs along the way. And you can enjoy all this extra “oomph” in extreme comfort and total sound isolation because of the thick squashy, king-size ear cushions. Get ready to for a bass attack.

Recreating the dancefloor experience

“A key feature of the XB series is that they deliver a deep, thumping bass line. They were originally developed based on the assumption that they would recreate the sound field of a club dance floor because both Matsuo and I belong to the generation that grew up listening to club music, so we are familiar not only with the sound that you hear from the best se at in a concert hall, but also with the sound that washes over you from speakers that are taller than you are.”

Atsushi Komiyama, Headphone Designer

Perfect fit for anyone

“Sony’s headphones have an ‘ear-conscious design’. The shape of the housing and the movable range are determined by detailed calculation of the angle of the ears, the shape of the face, etc. With ordinary headphones, the movable part is bigger to allow them to suit all angles, but with these headphones, the ear pads are so thick and soft that, to a certain extent, they fit any angle.”

Tomohiro Matsuo, Headphone Engineer

The bigger the better

“When we were making the headphones, the first thing we did was to come up with these king-size ear pads. When we were thinking about how to visually express the sound reproduced by the headphones, one of the engineers said he wanted to make some fun ear pads. No existing ear pads expressed the deep bass sound and beat that you feel on club dance floors by their very existence and we thought it would be fun to do that.”

Atsushi Komiyama, Headphone Designer

Feel the bass, mids and highs

“We gathered the best of the technologies accumulated during our long history in the field of headphones and devoted them all to these headphones. Of course, it was important to produce deep bass tones, but we didn’t forget the high tones too. On a club dance floor, you can feel the width, depth and movement of the sound all at the same time, so we thought it was very important to hear and feel the high frequency tones too. In that sense, I think we have achieved balanced sound creation.”

Tomohiro Matsuo, Headphone Engineer
