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.

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.

Fashion Enthusiast
Music Lover
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.
Driver Size
This refers to the diameter of the driver (speaker) on each side of the headphone.
Driver Type
The physical design of the driver in the headphones.
Primary Color
This is the main color of the item.
Secondary Color
A color that compliments the main color of the product.

I bought the Soul by Ludacris SL99 a few months ago as a gift for my friend, and as what he said the ear piece is really nice.

The headphones are almost good as I expected. Pros great for the price cons: would recommend Dr. Dre beats if you have the money. Experience: I own a pair of both.

I bought these over a month ago, and these are by far, the best headphones I ever owned! I like Beats by Dr Dre, but I was sick and tired of seeing everyone using them. The SL99s are geared more towards sound quality, and if you listen to all kinds of music and not just hip-hop, this will be the best $99 spent for earbuds. The SL69 is geared more towards those who like super deep bass.
The only downside is getting them to stay in my ears when I'm lifting weights in the gym. But if you're gonna use them to just sit and listen, you'll have no problem at all. Especially if you're on a bus trip, train, airplane, etc! And when they mean isolation earbuds, they mean it. Someone can have a loud conversation with somoene else next to you, and you won't hear ANYTHING.
If you're looking for an alternative to Beats by Dr Dre at a decent price, look no further because Soul by Ludacris is definitely a WIN!!!
