Bose SoundLink Bluetooth wireless headphones in black/blue. Compatible with any Bluetooth device. Also, has 3.5mm Jack and cable, and can hold up to 15 hr. playtime charge with rechargeable lithium-ion battery. Bought new a couple years ago from warehouse store (Costco , Sam’s, BJ’s) but never opened. Plastic wrapper was torn when I pulled out of storage so I took out and charged and tested. Everything works as it should. Charge holds as normal. Nice headphones and good reviews on other sites. I just don’t have a use for anymore.
