    Headphone Design

    Headphone Type

    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
    Headband 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
    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
    Headphone Application

    This is the application that the headphones are designed for. Each application has unique features that make it perfect for particular uses.

    DJ: These headphones are durable, loud, and will often allow for one ear listening.

    Gaming Delivers explosive sound and allows you to communicate with others.

    Home Hi-Fi: These audiophile headphones are engineered to produce high fidelity and accurate audio.

    Home/Office: These headphones are designed to produce rich, brilliant sounds that the artists would appreciate.

    Sports: Designed for active use. These headphones are made to stay in (or on) the ear during workouts.

    Kids: Feature noise limiting technology so that your little ones don't damage their ears listening to music too loud.

    On-the-Go: On-the-go headphones are lightweight and often fold up for easy storage and portability.

    Student: Compact and rugged enough to survive life in a backpack; inexpensive enough to not hurt the wallet of a student.

    Studio: Reproduce music perfectly without any coloration. Look here for reference quality studio monitoring headphones.

    Traveler/Airplane: These headphones are compact, lightweight, and have a portable design.

    Gaming
    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.
    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.
    Boom Mic
    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.

    Bluetooth means that the audio signal is transmitted from your device to the headphones via a Bluetooth connection.

    Corded or Bluetooth means that the headphones can be used as corded headphones or as Bluetooth headphones. They have an input in one or both earcups for use as a corded headphone while they also have a built-in battery for use as Bluetooth wireless headphones.

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

    Corded
    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
    Connector Type
    The type of connection the headphones use to connect to receive the audio signal from a music source. Traditional headphones use an analog 3.5mm headphone jack. Newer technology has allowed digital signals to be sent directly to the headphone using an Apple Lightning or USB-C cable.
    Jack Size
    Refers to whether the headphones use a 3.5mm or 1/4" headphone jack connection.
    3.5mm

    Audio Features

    Driver Type

    The physical design of the driver in the headphones.

    Balanced Armature:
    A balanced armature driver uses a coil wrapped around an armature which is held in between two magnets until it is stimulated by an electrical current. When stimulated, this armature is magnetized which causes it to rotate one way or the other around a pivot point which moves the diaphragm to create sound. Balanced armature driver headphones are generally earbuds and can have multiple drivers in each earbud.

    Dynamic:
    Dynamic drivers are the most common driver type. They feature a permanent magnet, usually neodymium, a voice coil and a conical diaphragm to drive your music. A dynamic headphone driver looks pretty much identical to any typical home theater speaker.

    Electrostatic:
    Electrostatic drivers are made up of an extremely thin membrane, usually a coated PET film, stretched between two metal plates. An electrical signal is applied to the metal plates to create an electrical field which, depending on its polarity, draws the speaker diaphragm toward one of the plates which forces air through the perforations in the diaphragm which generates the sound wave.

    Planar Magnetic:
    A planar magnetic driver is made up of a large membrane suspended between two sets of oppositely aligned magnets. An electric charge is applied to the membrane to induce movement and produce sound waves.

    Dynamic
    Impedance
    The opposition to electric current, a higher impedance means a higher electrical resistance. This is measured in ohms.
    32 ohms
    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".
    96 dB
    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).
    5 - 30000 Hz
    Audiophile
    Audiophile headphones represent some of the finest headphones available. Audiophile headphones produce genuinely outstanding sound quality as well as extraordinary build quality, components and comfort. They are truly the finest headphones available.
    No
    Built-in Amplifier
    This refers to whether the headphones have an amplifier built-in.
    No
