Ten years ago, I splurged on a premium Bluetooth speaker that cost me over two thousand dollars. A few years later, its battery gave out, reducing it to a wired-only device. On a sudden impulse, I took matters into my own hands and ordered a replacement battery. After carefully disassembling the speaker and installing the new power source, to my amazement, it sprang back to life like new.
This experience taught me a valuable lesson—it’s not about innate talent, but rather how necessity (and a tight budget) can transform anyone into a DIY expert.

That’s a great DIY guide! I’ve been thinking about restoring some old B&O speakers I have at home. The step-by-step approach in your post definitely makes it seem doable. I’ll check those part costs first since 80 yuan is a steal for a good revival!
