Thank you guys, the thing is the winter is approaching and i will be growing my potato roots on the coach more often and listening to music with my headphones, and to be honest, i am getting very tired of controlling the volume with my phone, doesnt add much to the experience, i prefer much much better the feeling of a volume knob and not having to open my eyes and scroll through the screen, specially in the semidark.
Sure i can keep on doing that, but if one of those things exists, i would definitely want to give it a try.
A simple remote could be a not so bad substitute, but a nice round knob with a decent feeling would make me a happy potato.
Thanks!
