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.

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.

This is the lifestyle that the headphones are designed for. Each style has unique features that make it perfect for particular people.

Designed for those that are active. These headphones are made to stay in the ear during workouts. Whether you frequent the gym a lot or go running outside in the fresh air, these active style headphones will be your best friend.

For those that need the best in music quality. These audiophile headphones are engineered to produce high fidelity and accurate audio replication.

Disc Jockeys (DJs) require a special type of headphone that can meet their professional needs. These headphones are durable, loud, and will often allow for one ear listening.

Fashion Enthusiast:
For those that want to make a fashion statement with their headphones. Not only are these headphones designed with great sound quality in mind, but also great looks!

This lifestyle speaks for itself! If you love video games and want a pair of headphones that will deliver explosive sound and allow you to communicate with others, this is where you need to shop!

Music Lover:
These headphones are made to sound great. They are designed to produce rich, brilliant sounds that will play your music in a manner that the artists would appreciate. These headphones are for those that love music.

Musical Production / Recording Artists:
You're a music creator. Whether you're producing and mixing it down or in the studio recording yourself, you need a pair of headphones that will reproduce the music perfectly without any coloration. Look here for reference quality studio monitoring headphones.

Headphones need to be affordable and durable to keep up with the student lifestyle. A variety of styles can be considered a pair of student headphones.

Those that often find themselves on planes or on the road a lot. These headphones are compact, lightweight, and have a portable design. Some of the headphones in this lifestyle will feature noise cancellation technology that will help shut out outside noise.

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.

General Features

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.
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.

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.

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.
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.
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).
30 - 20000 Hz
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".
102 dB
Driver Size
This refers to the diameter of the driver (speaker) on each side of the headphone.
30 mm
Driver Type
The physical design of the driver in the headphones.
The opposition to electric current, a higher impedance means a higher electrical resistance. This is measured in ohms.
33 ohms
Primary Color
This is the main color of the item.
Secondary Color
A color that compliments the main color of the product.

I have owned two sets and the audio is great. The plastic where the 'R' and 'L' are breaks easily. Two sets are useless because the plastic broke.

Good one

September 18, 2013

I've had two of these headsets and would buy another if necessary. The price is very good, and the sound (I watch movies) is great. The sound cancelling feature leaves a bit to be desired, but this headset is very affordable. Also, this headset is very "floppy", but it is comfortable to wear for long periods, and is easy to adjust. Why is this my second identical headset? I broke a plastic piece that holds one ear phone on the first one.

Great Headphones

March 12, 2013

My husband got these for me for work. When we have the printers going for hours it's nice to slip these on with or without music to drown out the whine of the printers.
Need another pair for home!
