Sony’s original design (BA) Driver unit
The unique T-shaped Balanced Armature directly drives the diaphragm for a more linear motion and clean, faithful high notes.
Integrated magnesium alloy inner housing
The BA units are held firmly in an integrated, high-rigidity housing. This helps to eliminate vibration and keeps sound clear and clean without losing even a micro nuance of sound.
Preformed ear hanger for ease and stability
The IER-M7 In-ear headphones stably fit your ears through the universally shaped ear hanger. With firm fit and optimal housing shape, each ear bud stays in the right position.
13 variation of ear buds
Our earbuds come in thirteen variations – six triple comfort and seven hybrid silicon. So you can find a snug fit for all kinds of ear shape. Combining hard silicone rubber and specially-developed formed silicone, they are comfortable to wear for long lengths of time.
