A detailed teardown (via PopMech) of a pair of Beats’ immensely popular Solo headphones conducted by hardware-focused venture capital firm Bolt has some answers buried beneath. The headphones are incredibly cheaply made. The company cuts corners everywhere it can; gluing pieces together instead of using screws, and reducing the amount of tooling wherever possible. Amazingly, for all the company’s claims about precision sound design, the headphones use freaking off-the-shelf drivers!
As if this wasn't reason enough?! I still can't believe that Apple was tricked into buying such a shitty product! And yes, I Have tested and spent spent $399 on their Stuido Pro but promptly returned them one hour later. Trash!
Do yourself a favor and go with some Grados. The best $100 on headphones you can spend are on the Prestige Series SR80e.
Also of not, their "award winning" Beats Solo are essentially filled with extra metal for added weight to trick you into thinking they are substantial.
