Okay, the best IEM's I ever had were the Sleek SA6's, I loved those. I most currently bought some Phonak Audeo's, but the eartips did not stay on and I've lost them. I'm not looking to replace the eartips as I didn't really care for them that much. But according the filters of the Phonak's, I prefer mids above the rest, but I loved being able to have a punchy bass with the Sleek's and have guitars brought out too, and I hate vocals being lost. My musical taste is all in rock and metal from Paul Simon to Cradle of Filth and I love acoustic music. I'm not sure what mp3 player I will be using, I'm asking about that currently 'cause I need a new one of them as well. I would like to try and keep my budget at no more that $500USD but I'm willing to look into more expensive options if they suit me better. Any help is greatly appreciated and I thank you in advance.
