Here's a review from Turntable Lab (Grado - GR8 In-Ear Headphones - Turntablelab.com):

the lab review

Grado enters the in-ear market with the GR8. The GR8's feature Grado's renowned quality and top notch sound reproduction as well as a proprietary wide bandwidth moving armature design providing the listener with unsurpassed performance. The small size allows earphone to nestle well within the ear canal, maintaining an excellent air seal for improved bass and reduction of outside noise without causing discomfort. Includes 3 pair ear tips (small, medium, large; proprietary blend of two silicon rubber materials) for a custom fit, 4 ear wax proof cloths, and 2 ear wax proof cloth rings. Recommended.

The review doesn't say much. In fact, from looking just now, Turntable Lab just copied it from Grado's site... but they must be GR8 if they're recommended at $300.
