Sennheiser ie800s

in-ear answer for those that love their 800 series open-back full-size
headphones but want something with better isolation from outside noise and that
is more portable.

From the Sennheiser website:

IE 800 S

Sleek and compact, the IE 800 S is a giant where it really
matters: in reproducing music. Featuring a refined version of our proprietary
Extra Wide Band (XWB) drivers, it redefines the benchmark for crisp and clear
in-ear sound performance. The extraordinary musical capabilities of the IE 800
S are complemented by a perfect fit thanks to Comply™ foam ear tips. A cool and
attractive look tops off this handcrafted piece of aural excellence.

An in-ear masterpiece

Incorporating the next evolutionary step after the
groundbreaking IE 800 ear-canal headphones, the IE 800 S contains great
technology within a very confined space. Fitted with pioneering solutions like
the proprietary 7-mm transducers that create an almost unbelievable sound stage
and our patented dual-chamber absorber (D2CA) system, the IE 800 S conquers new
aural territory for high-end in-ear headphones.

The music unfolds inside your mind

Strikingly rich in detail, the IE 800 S generates a
stunningly lifelike sound image. Offering brilliant trebles as well as a
precise and improved bass sound, these in-ear headphones create the most
beautiful musical landscapes for your mind to wander around in. Explore your
music in all its glorious depth.

A brilliantly engineered sound experience

The IE 800 S features our patented dual-chamber absorber (D2CA)
system. This innovation overcomes the "masking effect", where
low-volume components of a sound are obscured by much louder sounds in a lower
frequency range occurring at the same time. Removing the energy from any
masking resonances to prevent unwanted peaks, the absorber system makes sure
even the finest nuances of sound become audible – enabling a truly high-end
listening experience.

Custom-made wearing comfort

Supreme sound can be best enjoyed when it comes with supreme
comfort. Thus, with the IE 800 S we introduced ergonomically designed
viscoelastic memory foam ear tips from Comply™. They shape themselves to each
individual’s ear canal for a custom fit, providing great comfort as well as
excellent attenuation of external sound.

Attractively handcrafted in Germany

Engineered and handcrafted in Germany, the IE 800 S looks as
immaculate as you would expect: modern, elegant aesthetics with an attractive
matt black finish to its premium scratch-resistant ceramic housing. The IE 800
S even shows its style when it’s not in use, with the newly designed premium
leather case for easy storage on the move.
