Westone W40 Quad Driver Earphone

The Westone W40 is packed with four symmetrically balanced armature drivers that will take your listening experience to an entirely different level. The internal three-way crossover network helps to deliver breathtaking clarity, realism and imaging while Westone’s True-Fit technology, and patented Star Tips provide superb ergonomics and comfort. The Epic Removable Cable with a low profile audiophile grade connector has high-strength and an ultra-low resistance tensile wire design with Aramid fiber, and Westone also throws in a 'G2 Round Cable' with built in 3-button Apple Control, volume and mic for calls.

Micro-Driver Balanced Armature Dual low frequency, single mid and single high frequency driver system put the W40 at the top of the heap in the generic fit in-ear world.  Here at HeadRoom we have found the Shure foam tips seem to bring out a bit more high end sparkle with the W40 and maybe a bit more comfortable to some.  Definitely consider purchasing a set for best results.
