e series: The Grado e series represents the company's third
generation of headphones. Every aspect of the headphones; the drivers, cable, plug, even the
glue; has been upgraded for better sound quality and dynamics. As in the
previous series, the e series headphones are all made by hand at
the Grado Lab facility in Brooklyn, NY.
Reference Series: Grado's Reference Series of headphones
feature real Mahogany wood, which undergoes a proprietary curing process to
enhance its natural tone properties. Because wood is subject to variations in
density, the curing process ensures consistency of the signature Grado sound.
The Grado Labs use Rhodium, the most expensive precious metal on earth, to
prevent corrosion on the connectors. New driver cones and voice coil have been
fine-tuned to be consistent throughout the frequency range.
RS1e: The Grado RS1e on-ear headphones have an open back design,
and are hand-crafted from real Mahogany wood. The natural wood, and Grado Lab's
advance damping treatments, help control and dissipate unwanted resonances. The
headphones utilize UHPLC (Ultra-High Purity, Long Crystal) oxygen-free copper
voice coil wire and state-of-the-art driver design. The 50mm drivers in the RS1e
are matched to within 0.05dB for optimum stereo imaging. The headphones also
have a genuine top-grain leather padded head strap.
8-Conductor Audio Cable: The RS1e has a high-quality 67"
audio cable with a 3.5mm gold-plated plug. This new cable design exhibits
greater control over the low and high frequencies, and lets Grado's world-famous
midranges sing. The plug has a sturdy molded sleeve
with ample stress relief. Included in the box is a gold-plated, snap-on 6.5mm
(1/4") adapter that you can use with your home audio components, and a 15'
Note: The size of the plug sleeve may cause interference with
some smartphone cases.
Replaceable Cushions: The high-quality foam rubber circum-aural ear cushions can be
removed for cleaning, if needed. If they show signs of wear, you can replace
them with the GradoReplacement Cushion
Note: The headphone's ear cushions are not covered in the
manufacturer's one-year warranty.
