I bought the Pioneer SE-MS7BT headset a little over five years ago and it has worked well the whole time. But now the surface of the ear pads has peeled off. Fortunately, these pads are available as replacements from various manufacturers.
Attaching the new pads is a bit cumbersome because the headphones do not have a flat surface, but are slightly curved in one place. But the result is convincing – the headset is now like new and the new cushions also fit very well.
