Hey, I need an IEM!
I'll be powering this via my laptop or my iPhone 4. I want to keep it less than $50.
I listen to a lot of music. I'd prefer something that has great bass, but is also good for vocals and guitar. I listen to Hip Hop, Acoustic, Trap/Dubstep, Pop.
Also, isolation isn't super important, but I'd prefer if it didn't leak too much sound.
Right now, the only IEM that I've been able to find that matches my criteria is the Brainwavz M4. Thoughts on that? Any other suggestions?
