ikanzi wireless earphones with charging case. The ikanzi T22 are ultra-compact, high-quality, and feature powerful bass, true wireless earphones. - Brand: ikanzi - Type: Wireless Earphones - Color: Black - Accessories: Charging case, USB cable I bought these, but I'm not a fan of earphones in general, and I use bone conduction earphones, so I no longer need these. I only tried them on once and charged them. I've uploaded an image of the same product page on Amazon where I purchased them. The design seems to have changed slightly. Please refer to it. Only the main unit, case, and USB cable are included. There is no instruction manual, but it seems you can find it on the website. Thank you for looking.
