For sale Backbeat wearable subwoofer

Due to some expensive upcoming surgery, I'm trying to raise cash to help offset medical costs so this is FOR SALE ONLY no trade offers, thanks. As most know, the Backbeat is a wearable subwoofer that can be attached to your strap or worn on your belt. It matches the pitch & intensity of the notes you play with a powerful rumble. No external amp or power is needed and unit is rechargeable. Complete your IEM experience on stage or use it to practice at home. I used it exactly once for a live gig before Covid made live music come to a screeching halt. Everything pictured is included. Unit, 1/4" input cord, charger, instructions, sticker, and carrying case ($20 option) ships with original box. New from BB this would run $328. $240 gets it shipped TYD.
