Audiophile, Premium, Best In-Class, Sennheiser

Sennheiser is a name that is synonymous with audiophile products. They have been viewed as a premium, top-tier (dare we say "The" top-tier?) brand since the beginning of time. Laboratorium Wennebostel's time that is. In 1945, Prof. Dr. Fritz Sennheiser founded Laboratorium Wennebostel's, or "Lab W" in a pleasant half-timbered house. Fritz Sennheiser was born with a gift. When he was 11 years old, he saw an early radio that inspired him to build a crystal radio. Again, he was 11 years old. There was no turning back from that day. The following year after founding "Lab W", Sennheiser produced his microphone. From that point on, it was one success story after the other. Sennheiser's technology continued to improve, and "The Bar" continued to rise. In the mid 60's, Sennheiser released the HD 414, the world's first "Open Headphones". That very day changed the future of headphones forever. That very same headphone, the HD 414, not only helped establish Sennheiser as a leading headphone manufacturer, but it sold over 10 million units. It is the best selling headphone of all time, and Sennheiser had just gotten started.

Headphone Design

Headphone Type

Headphone type refers to the construction of the headphones.

Around the Ear means that the headphones wrap around the ear to provide a secure fit. This is most often seen in active and sports headphones.

Around the Neck means that the headphones wrap around the neck. This is also seen in active and sports headphones.

Earbuds means that the right and left sides of the headphones are separated and will fit securely into the ear. These are small, compact, and user friendly.

Over the Head headphones mean that the right and left speakers are connected with a support that goes over the head and rests on top. This is the typical headphone type.

Over the Head
Earpiece Design

This is the design of the earpieces on the headphones. Some headphones go inside the ear, while others rest on the outside of the ear. This helps you know exactly what type of headphones you will be receiving.

In-Ear: The ear buds go into the ear. Most often, the right and left ear buds are two separate pieces.

Enclosed-Ear: Usually are found on the larger headphones. They rest on top of the ear and have padding for comfort, as well as enclosing the ear to the speaker. This type of headphone helps to filter out surrounding noise.

On-Ear: This type of headphone involves the speaker sitting gently on the ear without going in the ear or sealing it off.

Enclosed-Ear
Specifically For
Some headphones can use an IR Transmitter in your vehicle, while some can be plugged into your media device and be used on the go or at home.
Home/Portable

Acoustic Principle
The basic design of the headphones. There are 3 different types: Open: Have ports that allow air through the back of the diaphragms, enabling the headphones to sound like the music is coming from an outside source. Closed: Completely sealed and have no air passing through the diaphragms. Sounds like you are in a closed off room. Semi-open: Have slots or ports in the back of the cup and are partially open. This allows for a mixed sound between an open and closed headphone.
Closed

General Features

Noise-Canceling
Noise Reduction technology removes unwanted noise from a signal. Background or ambient noise can be removed to produce clearer speech and enhanced hearing. Typically these Active Noise Canceling (ANC) headphones are powered and use batteries to activate the noise canceling technology. Also referred to as Noise Reduction or Noise Cancellation.
Yes
Headphone Connection
This is how the headphones connect to the audio source.

Corded means that the headphones use a cord to transfer the audio signal.

Wireless means that the audio signal is transmitted wirelessly to the headphones.

Corded
1/4" Stereo Jack Adapter
Some headphones will come with a 1/4" stereo jack adapter to connect the usual 3.5mm jack to a 1/4" stereo plug.

1/4" Stereo jack is a larger audio jack that select electronics have.

No
Volume Adjustment
Volume Adjustment means that the headphone (independent of the source) can adjust the playback volume. Many headphones and ear buds have in-line volume control, which allows adjusting the audible volume from a switch on the headphones cord. Other headphones have a volume knob on the headphone can.
Yes
Built-In Microphone
This means that the headphones or earbuds have a built-in microphone. This can be a microphone on the cord, built into the headphone, or even a boom microphone. These mics can be used for music devices like iPods, for Smartphones to make and receive calls, or for gaming purposes.
Yes
Frequency Response
The range of frequencies the speaker will reproduce (lowest frequency to the highest). Bigger is better, meaning the wider the range, the better. The optimal range is 20 - 20,000 Hz (which is the range of human hearing).
8 - 28000 Hz
Sensitivity
An efficiency or sensitivity rating tells you how effectively a speaker converts power into sound. The higher the number, the more efficient the speaker and the louder it will play with the same input power. An efficient speaker helps you maximize your available power. Most sensitivity ratings measure the speaker's output with 1 watt of input, 1 meter from the speaker. Some speakers' sensitivity is measured with 2.83 volts of input, instead of 1 watt.
 
Efficiency (1w/1m) is not an accurate indicator of a subwoofer's output capability and should not be used as a comparison to other speakers or subwoofers to determine which one is "louder".
108 dB

Only The Best!

May 11, 2014

I purchased these to replace an old pair of Sennheiser NR phones I've had for about 15 years. While I liked my old ones these are far better both in design and operation. The battery is internal, the ear cups swivel 90 degrees for storage, they come with a case (a very nice case) and the cord is detachable. Those are all changes for the better, but the fact that these leave the Bose in the dust is the real reason to buy them. They are only the best!

Superb sound quality

March 14, 2014

Sennheiser quality sound comes through with and without noise cancellation on. The Talk-Through button is useful when you need to speak to flight attendants. Comfortable to wear and the volume control is convenient. Noise cancellation is at 80% which may not cut out all airline noise but definitely worthwhile.

Superb product

December 5, 2013

I have used these in train trips with great satisfaction. Above all, comfortable to wear for long period of time (4 Hrs +), gone is the "ear fatigue" I used to have with my previous (not as expensive) headphones. Sound superb too. Good value considering the built and sound quality you get.
