Tellegloww Ghost Hunting Box Speaker, Ghost Hunting Equipment, Portable Speaker with 3.5mm Aux Audio Interface for Home Office Outdoor Paranormal Gift Supplies, Plug and Play for Phone Tablet

No idea why they market this as “ghost hunting equipment,” but this little $16 speaker has some surprising kick behind it. Just don't expect any exceptional audio quality, it has almost no bass. The back sits almost flush on an uncased 30, but feels light enough that I haven’t worried about strain on the aux jack. Perfect for listening in the shower or while doing dishes. Link for those interested.
