Bluetooth Audio Device for Guitarists

I am seeking a skilled engineer to develop a simplified Bluetooth device capable of streaming audio. Primarily used by guitarists, the device should be able to efficiently transmit sound to headphones, focusing only on this main function. Your task would be devoid of incorporating features like voice control, noise cancellation and multi-device connection. Your experience with audio technology and understanding of guitar-based audio will serve as an added perk.

Ideal Skills:
-BT Audio Engineering
-Understanding of Musician Needs
-Experience with Audio Transmission Technology
