Warning: Do not repeat what I've done in this video. Teardown may puncture battery, parts, and kill an amplifier or speaker driver.
This video shows what inside of the Edifier MP85 bluetooth speaker.
Edifier MP85 speaker enclosure is a sealed box. Most of the chinese speakers rather than buying Edifier speakers have fake seal enclosure inside the speakers that make the air enter or exit from the ports. But this speaker has a real sealed box speaker enclosure. This speaker doesn't have a bass port, just like the Logitech Z120 (Wired speakers).
