I am selling this item because I purchased it for my elderly parent, but they never used it. I tested it to check the power and functionality, but it has not been used for daily use. I believe this would be helpful for elderly people who have difficulty hearing the TV or other sounds unless the volume is very loud. Everything that came with the purchase is included. * High-performance digital rechargeable hearing aid for the elderly and those with moderate hearing loss * Easy to wear, over-the-ear type hearing aid, suitable for both left and right ears * Approximately 5 hours of charging provides up to 36 hours of use * Equipped with both low and high-frequency modes, allowing for sound quality adjustment * Made of high-quality silicone for comfortable wear even over extended periods
