What's better than an electrostatic speaker, why, an electrostatic headphone, and what's better than an electrostatic headphone, well quite possibly an electrostatic element inside your head.  Enter the Stax SR-003MK2.  We dare you to find anything as delineating and pleasing near this price.  Stax has made in-ear monitors for some time but they are often over-looked due to the renown of their reference cans.  These in ear speakers come with three silicon molds to fit your ears, and with a choice of two drivers, (one for the road and one for the desk), you can have reference sound wherever you please.  You can also use the IEM's with or without a headband.

Below are descriptions of the two driver units:

The SRM-252S,  perfect for a desk at about the size of a cd jacket:

The SRM-252S is an exclusive driver unit (amplifier) for driving STAX ear speakers with PRO-bias 5 pins. Its line input can directly connect to the audio output terminal of CD player, portable audio player and PC. The SRM-252S has a simple design that excels in sound quality employing the carefully selected newest high-voltage transistors and low-noise FETs. The output stage featuring the emitter-follower configuration reinforces the driving performance and also realized the smooth sound quality. Moreover, the class-A amplification throughout the stages with no coupling capacitors reproduces exhaustively the finest nuance of music. Although the SRM-252S includes a class-A DC amplifier in a compact CD jacket size case, the internal heat is effectively dissipated through the chassis of aluminum extrusion material to improve the reliability over a long period of time. Also, the parallel output terminal was added to distribute the source signal so that a loud speaker may also be simultaneously used when source equipment has only a pair of output terminals.

AND...The battery powered SRM-002: for 'on the go' listener:

The SRM-002 is an exclusive driver unit (amplifier) for driving S-002 earspeaker. Newly designed power supply for extended listening on battery without performance loss. Switchable power mode between Normal (performance) or ECO (battery saving)

These should be shipping soon.  Really, headfi this good at this price is just very rare indeed.
