I have decided to spend $30 on in ear earphones and try them out personally, after all the people I saw on YouTube praising the new kind of earphones that go directly inside your ear. My choice were the SONY MDR-XB50AP with Extra Bass. The box looks great, it's glossy with a sort velvet feel. The materials and building quality are excellent, And this is it. Apart of cool design, they are useless for humans.
As soon as I've put the earphones inside my ears, I have discovered that this kind of design simply doesn't work. First of all, being inside the ear, you start feeling discomfort after about 10 - 15 minutes. Second, being inside the ear, every time the cables touch anything, you hear it loud inside your ears. The audio is completely shitty. All you hear is distorted bass spectrum, without hearing the high spectrum.
Verdict: Now I have $30 useless in ear earphones with cool design. Stick to classic earphones.
