Customer feedback:

1. I was looking for phones that would pack plenty of punch without sacrificing any of the qualities of their full-grown, ostentatious siblings. Anyone who's even moderately serious about headphones knows that the smallest improvements come at a price. In the case of these phones, the cost is easily justified. I've compared them with several portables in the $5-10 range along with some full-sized models weighing in at $50-100. Conclusion: these are worthy of being your "front-line," and perhaps only, pair of phones. They're up to the task of distinguishing each of the instruments in a jazz rhythm section or reproducing the spacious quality of an entire string section. The treble is distinct and "alive"; the bass is, if anything, more than I require (and the PX 200's are supposedly the bass-heavy models). Comfort? They feel the same as any $2 pair of portable headphones--until the music begins, at which point "wearability" is not even an issue.

2. The PX100s are small, unobstrusive phones. They're suited to portable music players (portable CD and MP3 players), as they are relatively efficient and drive well for the most part. They are small and thin, so you won't look like a complete geek or goofball wearing them in public, and they fold up cleanly and could easily fit in a shirt or pant pocket. They also include a carrying case. The build feels flimsy, but they are actually far more durable than one would imagine. The cord is thin, so beware snagging it too sharply, and short (these are not for use with a home system). They are also extremely comfortable, with a large "sweet spot" and light weight.

Denon AHD1001K On-Ear Headphones (Black)

Denon is the company that invented digital recording over thirty years ago. They have led the audio world with leading edge technologies in audio and video sound reproduction. Now you they have taken that same attention to detail and put it into the design of an incredible series of headphones. The Denon AHD1001K On-Ear Headphones are designed to reproduce all of the nuances of the digital music you listen to. The microfiber diaphragm with acoustic optimizer provides superior sound quality from 8 to 37,000 Hz. High-quality, oxygen-free copper cabling ensures only the cleanest sound. This headphone also features an attached 5-foot cable and 11.5-foot extension cable.

Technical Details :
* On-ear headphone design.
* Black metallic finished molded housing and light weight magnesium frame structure.
* Microfiber diaphragm with acoustic optimizer.
* High-quality oxygen-free copper cabling.
* Cloth mesh cable jacket and carry pouch with L-type connector included.



CUSTOMER FEEDBACK :
- Clarity and detail is very good.
- Midrange is solid and not too forward, it works well for both female and male vocals. - Everything from the mid-bass on up is well represented. Kick drums sound realistic with good punch and authority.
- The placement of performers in the recording is precise and fairly spacious.
- The slightly elevated highs means this headphone can sound a bit forward if the music is recorded on the "bright" side.

The bad thing: Although these are sealed headphones that should block out some noise, they barely block out any noise at all. They only block out 10dB of noise which means you hear the noise at half the intensity, which is not enough for reducing the noise of my noisy cubicle mates.

Sennheiser HD800 Premier Headphone

The Sennheiser HD-800 is the headphone that has been specifically engineered in replicating the basic acoustic conditions of natural hearing.The HD-800 is the ultimate headphone to deliver nature.
The impression of spatial listening is created by a minute time lapse with which one and the same sound wave arrives at the inner ear. Ideally, the sound waves produced by a hi-fi sound system reach the listener at an angle of 60 degrees. The sound waves do not reach the ear straight on, but through a slightly angled sound front. This causes some of the sound impulses to reach the nerve ends of the inner ear earlier than others. The resulting time lapse is a matter of split seconds, but it is exactly this phenomenon that gives the impression of spatial listening.

Technical Details
* Natural hearing experience - realistic and natural sound field with minimal resonance.
* Biggest transducers ever used in headphones up to today - new innovative dynamic transducer design.

The transducer is designed in the shape of a ring. Basically, the larger the surface of the transducer the purer the sound—particularly when it comes to the low notes. A large surface area, however, also generates disruptive spurious oscillation at higher frequencies, so-called eigenmodes. This is primarily due to the fact that conventional-sized transducers do not have a satisfactory way of controlling high-frequency oscillations. The ringed shape of the new transducer effectively solves this dilemma: Its broad area oscillates in an extremely controlled way due to the large coil and the two supporting surfaces. This results in a previously unheard-of degree of freedom from distortion and thus the greatest purity and brilliance of sound.
The ring-shaped transducer utilized in the HD 800 greatly enhances the control of the oscillating surface. This results in a more voluminous sound wave and thus far greater clarity. In a conventional transducer, unwanted spurious oscillation can occur due to eigenmodes. Even improvements such as increasingly sophisticated Duofol laminations are unable to completely negate these physical limitations.
The symmetrical cords are designed with twin-core, high-performance, Teflon-insulated connections on each side. They are additionally covered with high-quality material for better shielding from oscillations caused by ambient noise. The jacks are exclusively produced for the HD 800 in Switzerland and feature gold-plated bunches. Gold has the highly positive property of having a very low transfer resistance, thus guaranteeing excellent contact without interference.
The headband consists of a sandwich design in which a metal layer is covered with several layers of plastic. The high-tech plastic possesses incredible attenuation characteristics and ensures that oscillations are not transmitted to the headphone mountings.The headphones of the HD 800 are only mounted on one side, to make sure they fit optimally over the ear. The relocation of their point of balance towards the back of the head also enhances comfort for the wearer.
