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.

On-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.

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.
No
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.

Yes
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.
No
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.
No
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).
10 - 24,000 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".
104 dB
Driver Size
This refers to the diameter of the driver (speaker) on each side of the headphone.
40 mm
Driver Type
The physical design of the driver in the headphones.
Dynamic
Impedance
The opposition to electric current, a higher impedance means a higher electrical resistance. This is measured in ohms.
36 ohms
Primary Color
This is the main color of the item.
Black
Secondary Color
A color that compliments the main color of the product.

Don't let the low price fool you. These are incredible!

May 16, 2014

I own two sets of $300 Seinheisers, and some pricy ATH cans, but when I really want to hear incredible detail, these are the headphones I use. In fact, I just bought a second pair, and don't even intend to take them out of the package for a year or two. They are good enough, I want to make sure I've got another set when the first one wears out. These phones are very clean and detailed, they have a very strong and tight bass, and they kick out twice the volume level as most most headphones. These are the best value headphones I've ever found.

Excellent budget headphones

May 13, 2014

These are about as good as it gets for the price and type of headphones. Comfort is pretty good and sonics are great for the cost.

Best headphone value, period!

April 14, 2014

I learned about these headphones while looking for some good phones for my recording studio. I bought these the same time as I bought some $299 Seinheisers (I also have expensive Audio Technica phones) . I've not found a set of cans yet that beat the detail and definition of these. You'll hear nuances and details in recordings you've never heard before. They are also very sensitive, in that they will give you a high level of volume from low power sources. It's hard to be believe, but in terms of detail, these beat my expensive cans. They also have a very solid and well defined low end. My only concern is that the low end may be a bit stronger than I want. But its still very precise, so it's not a significant problem. It's not mushy on the low end like may headphones. At $29.00, they compare favorably with sets costing ten times that much. I like them so much, I'm ordering more.

Big dissapointment

July 29, 2013

From reading all the reviews I expected more. Don't kid yourself. It is still a cheap pair of earbuds and they sound cheap too. I own several earbuds and while some of them show their strong side in either treble, mids or bass, the 400B has no such qualities.
