The updated Sony MDR-EX700LP earbud headphones sport new 16mm drivers to give you ear-drum-shattering action (108dB) with "more precise sound" (4-28KHz) than before. Sony says the magnesium-housed MDR-EX700LP earbuds have a new "multi-layer diaphragm for reproducing high resolution sound." For $300, that better be a lot of layers and a lot of high-res sounds.
