I'm on a low budget so I bought some cheap Sennheiser CX300-B, but i'm trying them out right now and there seems to be some problems...
The left side seems "lacking" compared to the right... I tested the earphones with a solid sine oscillator at 50~100Hz, panned completely to one side then the other, and the left side definitely sounds... weaker. Then I switched sides and tested the left plug on my right ear... same results.
Is this normal with new products (albeit cheap)? Would it get better once I burn it in?
Oh and another thing that i noticed is that if i accidentally flick the cable, it creates a bassy kick-drum-like sound, but only when it's plugged in. And yes, the sound is actually coming out of the earbuds... I held the wire into a loop and at arm's length, under my desk. If it's plugged in when i do that, it makes a noise, but not when i try it unplugged.
Is that... normal?
