Benefits of technology

This patented technology allows an audio playback system (Bluetooth) player that works on both BT modems and wireless networks to have two separate chips - one called handheld chip while another uses blinds instead of lamps at all times during call setup sessions. These earpieces help reduce noise from loudspeakers used by other devices like smartphones without being noticed over their own ears. Additionally, this design includes a USB port connected through computers for internet access. Overall these technical features improve sound quality compared to traditional speakers.

Problems solved by technology

This patented technical problem addressed in this patents relates to how many times individuals want their own device or accessory like earbuds that can communicate over Bluetooth without being able to work together on one another when they only require talking from them individually.
