Repair Sony MDR-100ABN active noise cancelling headphone

此耳機電池容易因為過放而耗盡, 因為產品線中止, 只能自己換電池

The battery will drain out easily. Due to product discontinued, you can only replace battery by yourself

拆開耳機需要 取下耳罩泡棉

之後拆開螺絲, 注意, 電池在沒有NFC icon的另一側

unmount screwes on the side w/o NFC icon

然後你就會看到電池, 型號SP-70/A

Then you see the battery. Model SP-70

該型號已經停產, 因此需要找個相容品, 在台灣最適合的相容品為NP-BK1

The battery discontinued too, so you need a compatible product. The best option you can get in Taiwan is NP-BK1. (In the US, there's SP70A compatible battery on Amazon)

你只需要多塞一點泡棉,以及膠帶固定, 接點完全相容

All you need is to insert foam & tape it. Battery pads dimension/position is totally the same
